purchase of a Siemens ELMO-PackTM oil sealed liquid ringvacuum system.By carefully following the procedures outlined in this manual forinstallation and operation of your system, you will guarantee years of satisfactory systemperformance.The ELMO-Pack TM Oil Seal System is a liquid ring vacuum pump package with a self-contained cooling system. The system is designed to operate with a low viscosity sealingoil that is provided with the system. This oil will provide increased vacuum levels(deeper vacuum) at increased operating temperatures. The pump can operate at a highertemperature without cavitation and without loss of operating liquid due to evaporationbecause oil has a much lower vapor pressure and higher boiling point than water. Normaloperating temperature for the system is 150 -190F.The ELMO-Pack TM systems are available in a variety of sizes.They can be provided ina standard SIMPLEX configuration or an EXPANDABLE configuration.1.2 Operating PrinciplesThe ELMO-Pack TM oil seal liquid ring pump uses proven liquid ring technology toprovide a reliable mechanical vacuum system. The liquid ring pump is the most importantcomponent in the system.A rotating impeller is used to make the operating oil flowaround the inside of the pump casing.The oil forms a seal between the impeller blades,port plates and casing.The gas is compressed in this sealed chamber.Because heat is generated during the compression, the discharge of the pump is hotterthan the suction.The operating oil absorbs most of the heat.Since the oil and inlet gas(usually air) are mixed at the discharge, it is necessary to separate the two prior todischarging the gas to the atmosphere.To do this, a borosilicate gas coalescing filter isplaced in the discharge, which removes all of the visible oil from the gas beforedischarging.The filter is located in the upper portion of the discharge separator vessel.This vessel is large enough to hold about two minutes of oil supply, which is recirculatedback to the vacuum pump.The discharged oil is hot and must be cooled during normal operation by passing througha cooler.At start-up, however, the extra oil in the separator is relatively cool (roomtemperature).Since any water vapor in the suction stream could condense if thedischarge is too cool, it is desirable to heat the oil quickly.Therefore, a thermal bypassvalve is placed in the oil re-circulation line.This valve lets the oil bypass the cooler untilit gets to about 150F.Once it reaches 150F, the valve mechanically switches and theoil is passed through the cooler.7The cooler is designed to remove the thermal load, about equal to the motor horsepower,from the oil before it is sucked back into the pump.Since the cooler uses ambient air tooperate, the oil discharge temperature will be somewhat dependent on the local airdensity and temperature.CAUTIONOperating the system at altitudes above 3000 feet or more maycause discharge temperatures to be above therecommended maximum unless specially designed coolers are utilized.CAUTIONDo not operate the system in a closed room.Adequate ventilation is required to ensure proper operation.CAUTIONOperation of the system in ambienttemperatures greater than 104 F is not recommended.89Each system contains the following components described below.Refer to Figure 1-1 for relativeplacement in the systems.1.2.1 Siemens liquid ring vacuum pump.The Siemens liquid ring vacuum pump is the heart of the system. A liquid ring vacuumpump is a non-pulsating rotary vacuum pump that compresses gasses using liquid as acompressing medium. The Siemens liquid ring vacuum pump has a simple design forreliability. A single moving part, the impeller, rotates forcing the operating liquid to forma liquid ring within the casing. This liquid acts as a sealant, as a compressing media andas a coolant.Wear is minimized because there is no mechanical contact of moving parts.On the suction cycle, liquid recedes from the impellers hub, drawing gas to becompressed through the axial suction port.Because the impeller is off-center to the ringof rotating liquid, the liquid reciprocates into spaces between the blades much like theoperation of a cylinder, compressing the gas against the hub. After almost one revolution,the compressed gas is discharged through axial discharge ports.The Siemens variabledischarge port provides maximum efficiency at different vacuum levels.CAUTIONOn initial start up of the system, be sure to place the recommended (See Table 2-1) priming oil in the pump.This isin addition to the oil placed in the separator.Damage to thesystem is possible if this oil is not added on initial start-up.1.2.2 Electric MotorThe electric motor provides an efficient, reliable prime mover for the pump. A variety ofmotor designs can be provided including explosion proof motors and motors for a varietyof voltages. The correct motor voltage must be specified and is the responsibility of theuser.1.2.3 Air / Oil SeparatorThe liquid ring pump discharges both oil and air into a special discharge separator. Theseparator is designed to separate the oil from the air. The oil is separated and settles to thebottom of the separator tank where it is returned to the pump through the cooling system.The air is discharged through a fitting located at the top of the separator. The separatoralso has a port for convenient filling of the system.CAUTIONDo not fill the system through the discharge gas fitting.Use the oil fill port on the side of the separator.101.2.4 Coalescing FilterThe separator also has a replaceable internal coalescing filter. The air being vented toatmosphere must first pass through this filter. Almost all of the oil mist (99.97% of allparticles 0.3 microns or larger) is removed from the air stream and returned to the system.1.2.5 Heat ExchangerThe oil temperature is maintained by an air to oil heat exchanger with a motor driven fanand a thermal bypass valve.The heat exchanger fan motor passes ambient air over theradiator style heat exchanger and operates continuously. This cooling system is designedto operate in ambient temperatures up to 104F at altitudes of less than 3000 feet abovemean sea level.1.2.6 Inlet Check ValveThe inlet check valve provides a tight shut off and prolonged cycle life utilizing a uniquecontinuous elastomer around the valve bore.1.2.7 Inlet Vacuum GaugeThe inlet vacuum gauge is a bourdon tube type gauge and indicates the vacuum level atthe pump inlet relative to ambient pressure in inches Hg vacuum.The gauge is isolatedwith a convenient gauge cock to allow removal or replacement without affecting systemoperation.1.2.8 High Temperature SwitchA discharge temperature switch is provided to protect the pump from a high temperaturecondition. This switch has common and normally open contacts. This switch must be tiedinto the motor control panel. A high temperature condition will shut down the vacuumsystem. A high temperature condition can result in damage to the pump. The switch tripsat a temperature of approximately 200F.CAUTIONDo not operate the vacuum system unless thedischarge high temperature switch is connected.Operation at excessive temperaturescould damage the pump orcause early or excessive system wear.111.2.9 Thermal Bypass ValveThe oil temperature is maintained by an air to oil heat exchanger with a motor driven fanand a thermal bypass valve. The thermal bypass valve is a temperature-actuated valvethat allows the service oil to bypass the heat exchanger when its temperature is below150F.This cooling system is designed to operate in ambient temperatures up to 104F.1.2.10 Compound GaugeThe operating liquid compound pressure gauge provides the user an easy check to assurethat the oil system is running properly. This gauge should normally read a slight vacuum(1-8Hg Vacuum).The gauge is isolated with a gauge cock to provide removal orreplacement without affecting system operation.1.2.11 Pressure GaugeThe separator has a discharge pressure gauge located near the top of the separator. If thefilter becomes obstructed this gauge will indicate a high back-pressure. Normal range is 1to 3 psig.CAUTIONDo not operate the pump with a high discharge back pressuresince this will cause the motor to draw excessive power.1.2.12 Oil Level GaugeA separator level gauge provides easy monitoring of the system oil level. The oil levelshould be at the pump shaft centerline for Siemens model 2BE vacuum pumps (30 to 75Horsepower) and approximately even with the centerline of the operating liquid inletconnection on the pump for Siemens model 2AV or 2BV (1.5 to 25 Horsepower) vacuumpumps.1.2.13 Drain ValveThe separator is equipped with a separator drain valve. This will allow the user to drainaway water that may have collected in the system from the process and to drain the oil formaintenance and/or changing. Water will eventually settle to the bottom of the separatortank. The drain line is connected to the bottom of the separator tank for convenientdraining.1.2.14 Gauge CocksGauge cocks are provided with pressure gauges (items 7 & 10) to provide isolation of thegauges for easy replacement or removal without affecting system operation.121.2.15 Structural steel BaseA rugged structural steel base is provided with the system. When a non-expandablesimplex system is furnished, all equipment is supplied on one base. When an expandablesystem (simplex, duplex or triplex) is furnished, the control panel and a vacuum receivertank are furnished on a separate base, with each pump system on its own base.CAUTIONThe system should be installed on a flat, level surface.If anchored to the surface with bolts, take care in avoiding excessivepiping stress on the pump, which could cause leaks or vibration during operation.1.2.16 Temperature GaugeA discharge temperature gauge is provided to indicate the operating temperature of thesystem. The acceptable range is 150F to 190F.1.2.17 Ball ValvesThe Y-strainer can be cleaned without loss of oil by closing two isolation valves locatedat each end of the strainer. These valves should be fully opened during normaloperation.WARNINGDo not operate the system without oil or with any of the oil systemvalves in the closed position as severe damage can result.1.2.18 Y-StrainerThe oil is collected in the bottom of the separator and returned to the pump after passingthrough a Y-Strainer and the heat exchanger.The Y-Strainer is in the system to removeany foreign debris that may have been introduced from the users process.1.2.19 Sight Flow IndicatorA scavenge line is provided from the bottom of the coalescing filter to the suction port ofthe liquid ring vacuum pump. This will remove any oil that has collected in the bottom ofthe filter. The line runs externally from the upper portion of the separator tank (whichcontains the coalescing filter) to the inlet manifold on the pump.A sight flow indicator is13provided in this line. It is normal for a SLIGHT amount of oil to flow in this line.Aconstant flow of oil indicates that the coalescing filter requires replacement.[Note that asmall needle valve is included in high vacuum systems to allow operation above 28inches Hg vacuum.]1.2.20 Low Level Switch (optional)A separator low-level switch may be provided to indicate a low oil level condition. Thisswitch has common and normally open contacts, which should be tied into the motorcontrol panel using a time delay to eliminate false trips due to tank turbulance. A low-level condition should shut down the pump drive motor.Low oil level can result in lossof the liquid ring and possible damage to the pump.1.2.21 High Level Switch (optional)A separator high-level switch may be provided to indicate a high oil level condition. Thisswitch has common and normally open contacts, which should be tied into the motorcontrol panel using a time delay to eliminate false trips due to tank turbulance. A high-level condition should shut down the pump drive motor.High oil level can result inmotor overload and possible damage to the pump.1.2.22 Inlet Filter (optional)An inlet filter with 10-micron polyester element may be provided for applications whereparticulate matter may be present in the users process.1.2.23 Non-Expandible Control Panel (optional)1.2.23.1 Control Panel (optional)The optional base-frame mounted integral control panel is provided with motor starterincluding overloads, on-off switch, motor running light, high temperature light andhigh/low-level indicator lights. A reset switch is provided to clear any shut downcondition. The panel will automatically shut down the pump drive motor in the event ofover-temperature, low or high oil level (if supplied with the system) or motor overloadconditions. The indicator lights will show the reason for shut down. The panel has anhour meter that will indicate total running hours for the pump drive motor.The panel provides motor protection that will prevent motor burn out in overloadconditions. The operator should limit the number of across the line starts. This is toprevent potential motor damage from excessive starting. All electric motors require highstarting current and the number of starts per hour should be limited to the motormanufacturers recommendations (usually one hot or 2 cold starts per hour).The panel can be provided dedicated for one system (simplex) or can be ordered for anexpandable system.14CAUTIONThe non-expandable system panel does notcontrol the system vacuum level.If system vacuum level control is required,an expandable panel with PLC control is required.The non-expandable simplex control panel will be provided attached to the standardstructural base fame that accommodates the system.1.2.23.2 Power SupplyThe panel has been designed for the voltage indicated on the supplied panel-wiringdiagram.CAUTIONOperation of this system at voltagesother than those specified in thesupplied system documentationcan cause extreme damage.1.2.23.3 Combination/Non-Combination Starter PanelSiemens panels are non-combination types unless otherwise specified.The customer must provide a fusible disconnect or circuit breaker unless a combinationstarter is specified for the control panel.151.2.23.4 Non-expandable Control Panel DescriptionTable 1-1 Non-expandable control panel configuration.Simplex Control Panel(* indicates optional components)Operator SwitchesOn-Off (toggle)Reset (pushbutton)Indicator LightsDescription ColorPump Running GreenHigh Discharge Temperature Alarm Amber*Low Level Alarm Amber*High Level Alarm AmberInternal Panel ComponentsMotor Starter with thermal overload PUMPMotor Starter with thermal overload FANControl Power TransformerControl Power Fuses (Primary)Control Power Fuse (Secondary)Control RelaysRefer to Table 1-1 for panel configuration details.The heat exchanger fan and vacuum pump drive motors are protected by thermaloverload devices. Each overload relay has an adjustable setting that is factory set tomatch the nameplate full load current of the motors. If the setting is changed it will resultin improper motor protection. The settings should be checked to assure that they matchthe motor full load current value that is provided on the motor nameplates.161.2.23.5 Non-expandable control panel sequence of operationThe pump starts when the operator places the on-off switch in the ON position.Thepump will run continuously unless an alarm condition occurs.If the pump shuts downthe panel will display the alarm condition that caused the shutdown by illuminating theappropriate indicator light. This alarm light will stay on and the pump will stay de-energized until the user presses the RESET Pushbutton.When the RESET button ispressed, the pump will re-start unless an alarm condition is still present.If the pumpshuts down and none of the alarm indicator lights are illuminated, the motor overloadcould be tripped due to a motor overload condition. The motor overload relays have amanual reset button, which must be actuated to allow the motor to re-start.CAUTIONWhen the panel is connected to the users power supply, assure that theproper voltage is applied.Refer to the wiring diagram furnished withthe system.CAUTIONThe user must provide required primary circuit protection disconnectin compliance with NEC and local codes.This may be a fusibledisonnect or circuit breaker.CAUTIONOnly qualified personnelShould attempt to work on the control panel.Dangerous voltages are present.17181.3 Expandable SystemsAll ELMO-Pack TMoil seal liquid ring vacuum systems are also available as expandablesystems in either NFPA99 (National Fire Protection Association Standard for HospitalSystems) or Siemens Standard configurations.Expandable systems are available as simplex, duplex or triplex configurations from thefactory.The expandable panel can be ordered set up to handle up to three pumps.The panel ispre-configured for operation as a triplex system, so any expandable simplex or duplexpanel can be easily upgraded to handle additional pumps.CAUTIONModification of the Siemens panelshould only be attempted by a qualified electricianand done per manufacturers instructions.1.3.1 DescriptionThe expandable system consists of one or more simplex systems as previously describedplus an additional base frame containing a vacuum receiver tank and an expandablecontrol panel. Each vacuum pump system will be referred to as an Expansion Module.The system can handle up to three Expansion Modules.If it is initially ordered with oneor two pumps, additional ELMO-Pack TM Expansion Modules can be added later andfield installed.The additional electrical components can be field installed in theExpandable Control Panel by a qualified electrician and are included with each expansionmodule.The panel is pre-wired and designed to accept the expansion modulecomponents.A qualified plumber can pipe the additional expansion modules into thesystem.The panel is normally furnished in a NEMA 12 or NEMA 7 enclosure with non-combination starters. The customer must provide a fusible disconnect or circuit breaker.A normal NFPA 99 system includes disconnects.The Vacuum receiver tank is included to provide vacuum storage to accommodatechanges in demand from the customers process. The vacuum receiver is a Carbon steelASME code vessel that functions as an accumulator. If there are sudden changes indemand from the process, the vacuum receiver volume will respond by providing a storedvacuum source that will help maintain the system pressure.This will prevent excessivestarting and stopping of the pumps.The receiver tank is provided with a sight levelgauge and drain valve.191.3.2 NFPA vs. Standard SystemsThe expandable ELMO-Pack TM liquid ring systems are available as either standardconfiguration or NFPA 99 compliant systems.Both the standard and the NFPAconfigurations contain the same basic components, including:-Vacuum receiver tank-ELMO-Pack TM expansion modules-Suction piping-Inlet filters-Control panelInadditiontothesebasicsystemcomponents,theNFPA99compliantsystemincludes:-Discharge piping manifold with isolation values-Specially configured control panels with disconnects andredundant control voltage transformer.-Low vacuum pressure switch, alarm and reset button.For most industrial applications, the standard configuration is acceptable.NFPA 99specifications typically only apply to medical and certain lab applications.2021221.3.2.1 Expandable Control Panel DescriptionThe expandable panel is furnished with a Programmable Logic Controller. The panel canbe furnished with pushbuttons and indicator lights for one pump, two pumps or threepumps.

The settings should be checked to assure that they matchthe motor full load current value that is provided on the motor nameplates.1.3.2.2 Operation (25 HP or less)CAUTIONWhen the panel is connected to the users power supply, assure that theproper voltage is applied. Refer to wiring diagram furnished with thesystem.CAUTIONFor non-NFPA 99 systems, the user must provide a primary circuitprotection disconnect in compliance with NEC. This may be a fusibledisconnect or circuit breaker.These are provided per NFPA 99requirements on NFPA systems.The Expandable Control Panel provides manual or automatic operation of one, two orthree pumps. The requirement for running pumps is determined by vacuum switches.Ifthe system has three pumps and all three units are in the automatic mode position, thesystem will operate as follows: On start-up, all three pumps will be started immediatelyand will continue to run until vacuum increases beyond the set-point of VAC-1 vacuumswitch. This switch is set to the highest vacuum of all three switches. We will refer to thisswitch as the lead vacuum switch.When vacuum increases beyond the lead vacuumswitch set point, all pumps will shut down after a user adjustable time delay has timedout.The time delay prevents overheating of the motors caused by excessive repeatedstarts.System vaccum will decrease with process demand.When system vacuum decreases tothe set point plus the adjustable dead band of the lead vacuum switch (VAC-1), the leadpump will start. This pump will continue to run until process vacuum has reached the setpoint of the lead vacuum switch and the adjustable run timer TR-1 has timed out.If system vacuum decreases with only one pump running and reaches the set point ofVAC-2 (lagvacuum switch), the lag pump will start. Both pumps will continue to rununtil the system vacuum has reached the set point of the lead pressure switch and theadjustable run timer TR-1 has timed out.24If system vacuum continues to decrease with two pumps running and reaches the setpoint of VAC-3 (lag-lagvacuum switch), the lag-lag pump will start.All three pumpswill continue to run until the system vacuum has reached the set point of the lead pressureswitch and the adjustable run timer TR-1 has timed out.Each time the lead vacuum switch shuts down the pumps (on increasing vacuum), theroles of lead, lag and lag-lag pump functions will be alternated between pump #1,pump #2 and pump #3 to provide even cycle time for all three pumps.If one pump isshut down because of an alarm condition, the other pumps will continue to run ondemand as described above.CAUTIONOnly qualified personnelShould attempt to work on the control panel.Dangerous voltages are present.1.3.2.3 Operation (30 HP or larger)System panel configuration logic is custom designed for larger horsepower units to meetcustomer requirements.Please refer to the custom documentation included with yourlarge horsepower system for specific details of operation.1.4 Application LimitsThe ELMO-Pack TM Oil Seal System is a liquid ring vacuum pump package with a self-contained cooling system. The system is designed to operate with a special sealing oilthat is provided with the system. This oil will provide increased vacuum levels (deepervacuum) at increased operating temperatures. The pump can operate at a highertemperature without cavitation, and there will not be loss of operating liquid due toevaporation because oil has a much lower vapor pressure (higher boiling point) thanwater. Normal operating temperature for the system is 150 -190F.These systems are ideal where it is not convenient for a user to provide a water supply toa typical liquid ring pump application.25Liquid ring pumps are ideal for applications requiring a rugged vacuum pump that cantolerate entrained liquid and solids.However, there are some situations that requirespecial designs.If the following limits are observed, the standard system will give yearsof trouble free operation.-Ambient Temperature must not exceed 104F while using the standard motors.-Altitude at installation location must be 3000 ft. above mean sea level.-Water vapor or the condensable load must not be excessive.Contact the factoryfor assistance in determining if excessive vapor is present in your suction gas.-The use of an inlet filter is advisable if particulate matter is present in the suctionstream.This will prolong the life of the oil.-If reactive chemicals are present, special oils may be required.The standard oil isan ISO 22 non-detergent semi-synthetic (Poly-alpha olefin) oil selected forvacuum service.Contact the factory for assistance in selecting the proper oil foryour application.-Liquid ring pumps may not operate properly below 29 inches Hg vacuum.Ifexcessive vibration or noise at low pressures is experienced, contact the factoryfor assistance.-Maximum consumed power is at 20 inches Hg vacuum.It may be necessary toadjust the seal liquid flow rate at this operating point by throttling one of thestrainer isolation valves.-Operation of the system in dirty or dusty environments may require frequentcleaning of the radiator cooler.It is also possible to provide an air duct or filter tominimize fouling of the radiator.WARNINGOperation of the standard system outside the application limitsdescribed above could cause a hazardous condition,damage to the equipment and will void the factory warranty.26Section 2.0 Installation2.1 UnpackingInspect the ELMO-Pack TM System and pump carefully and note any signs of damageincurred in transit. Verify that the packing list and the received shipment are in agreementand all listed items are present.Since all systems are ordinarily shipped FOB our factory, any damages in transit are theresponsibility of the carrier and should be reported to them immediately. All ELMO-PackTM Systems can be lifted using a forklift on the underside of the steel frame. Never liftthe entire system by the pump and motor assembly only.When lifting, care should betaken to assure that the skid is secure and balanced.The skid can then be lowered ontowooden cribbing (4x4 timbers are suitable) so the forks can be withdrawn.The base should be lowered and leveled using jacks.Precision leveling is not required;level the base using a carpenters level.Although grouting is not required, the frameshould be continuously supported.The frame is provided with anchor bolt holes tosecure the system to the foundation.For maintenance, the Siemens vacuum pump and motor assembly can be lifted off of thesystems frame independently. See Maintenance section for lifting instructions. The inletport of the pump is covered for shipment as well as the exhaust connection on theseparator tank. This will prevent dirt or other foreign materials from entering the pump orseparator. Leave these covers in place until just before the piping is connected to theELMO-PackTM System.2.2 Electrical Power SupplyCheck the wiring diagram supplied with your system to determine the voltagerequirements for the unit and the type of disconnects supplied.WARNINGIf the voltage reported on the wiring diagram supplied with the systemdoes not match your supply voltage,contact the factory immediately.Do not attempt to install the system if the supply voltage and the systemvoltage requirement do not match, as a hazardous condition and severedamage could result.272.3 LocationThe ELMO-Pack TM must be installed on a horizontal, level surface. Floor anchors are notrequired because of low vibration levels. If anchors are used, care must be taken toeliminate pipe stress load on the inlet piping.A flex connector should be installed.At least 2 feet of air space should be allowed between any wall or obstruction and theheat exchanger air intake.This will assure adequate flow of cooling air and providemaintenance access.For expandable systems, place the vacuum receiver skid on the far left of the installationpad.Then place each expansion module next to the receiver skid and connect the pipingas indicated in Figure 2-1.For expandable systems, run the provided wiring from the panel to the vacuum expansionmodules.2.4 Wiring InstallationWire all components in accordance with the wiring diagram in Section 1.0, ControlPanel, or the wiring diagram supplied with your equipment.See Figure 1-2 (Non-expandable system) or Figure 2-2 (expandable systems) for details.If the system is supplied with a Siemens Panel, wire the power to the panel.28Figure 2-1 Typical Expandable System29302.5 Oil Fill and PrimeFill the oil reservoir with the recommended amount of Siemens vacuum oil. (See Table2-1.)All valves in the service liquid line must be open while filling the system with theseal oil.See Figure 4-5 in Section 4.4.2 for fill location on separator tank.Figure 2-3Priming the 2AV2 liquid ring vacuumpump prior to initial startup.CAUTIONDo not fill the system through the gas discharge port, as an oil cloud willdevelop on start up.Table 2.1 ELMO-Pack TM System Oil CapacityELMO-Pack TMBV2060BV2061BV2070BV2071AV2110AV2111AV2121AV2131AV2161 BE1153 BE1202BE1203BE1252System OilCapacity(Gallons)10 10 20 30 40 55Pump PrimingCapacity(Gallons)0.25 0.8 0.8 2.1NOTREQUIREDNOTREQUIREDBefore start-up, prime the vacuum pumps unit through the suction as shown in Table 2.1and Figure 2-3 if required.Priming is not required if the system has previously beenoperated and the vacuum pump was not drained.WARNINGDo not run the ELMO-PackTM system DRY!31Section 3.0 Operation3.1 Preliminary Inspection1.Check the seal-oil liquid level and prime the pump with oil as described inSection 2.5.2.Open all valves in the operating liquid line to allow service liquid flow.3.Make sure all drain valves are closed.4.Open block valves on all gauges.5.Check all piping making sure the connections are in accordance with Figure 2-2.6.Open any isolation valves in the suction and discharge piping.7.Check that the power supply to the motor has correct voltage and amperage asspecified in supplied wiring diagram.8.Isolate the power source from the motor to prevent accidental starting of the motorand system.9.Install all necessary disconnects in accordance with local codes.10.For each installed pump briefly jog the motor by placing the panel selector in themanual position for a few seconds.Observe the direction of rotation of the pump.Correct direction of rotation of the vacuum pump for BV2 and AV2 systems isclockwise when viewed from the non-drive end of the motor; for BE1 systems thecorrect direction of rotation of the vacuum pump is clockwise when viewed from thedrive end of the pump.Change pump or panel wiring(switch location of 2 leads) ifpump is operating in opposite direction from that indicated.WARNINGLocal codes may require and Siemens recommends installation of fuseddisconnects or circuit breakers within sight of the control panel.Standard control panels are not supplied with disconnects.Check local code requirements prior to installation.CAUTIONOnly a qualified electrician should attemptelectrical installation of this system.323.2 StartupWith steps 1 through 9 complete from section 3.1 (Preliminary Inspection), switch allpumps to auto mode.All vacuum pumps should start.Observe the vacuum gauge on theinlet connection. The gauge should start to indicate vacuum within 15 seconds. If novacuum is indicated, turn off the system immediately. Perform all steps 1 through 9 fromsection 3.1 (Preliminary Inspection).There will not be a vacuum if there is no systemresistance to gas flow at the suction.CAUTIONRepeated starts can cause overheating of the motor, which may result inmotor burnout (particularly for across the line starting).If repeated starts are made, allow sufficient time between trails topermit heat to dissipate from windings and rotor to preventoverheating.Please consult the motor manual.1. Confirm the oil in the separator is at the correct level and trace the operating liquidline confirming all valves are open and the seal liquid is flowing from the separator tothe pump.2. Confirm that there are no closed valves in the discharge piping from to the pump.(NFPA systems only)Run the system for hour and check for the following:1. Stable vacuum.2. No unusual vibration or noise.3. Operating temperature should be 150-190 F.4. Acceptable operating pressure at the separator should be 1-3 psig.5. Acceptable operating pressure for the operating oil at the pump should be 1-8 HgVacuum.6.Seal oil level in separator level gauge.3.3 Shut downThe ELMO-Pack TM system design makes shut down and re-start virtually one stepoperations. When the system is to be shut down simply turn the power supply to thesystem off. The ELMO-Pack Oil TM seal system is supplied with an inlet check valve toprevent any fluid being pulled from the pump back up into the system piping.333.4 Vacuum switch adjustment (expandible systems only)Each vacuum pump in an expandible system is provided with a pressure switch (SeeFigure 3-1) to control the vacuum cut-in point of the pump.The factory settings areoutlined in Table 1-2, Section 1.3.2.1.Each switch is field adjustable to alternate settingsby following the procedure outlined in this section.Figure 3-1Typical Pressure Switch3.4.1 OperationThe controls are actuated by vacuum.The following sequence occurs: 1) an increase invacuum (towards 30 in. Hg vacuum), causes circuit A-B to close and B-C to open (SeeFigure 3-2).This is the Trip setting.2) when the pressure returns to a predeterminedlower vacuum (towards atmospheric pressure), circuit A-B will open and circuit B-C willclose.This is the Reset point.The difference between the Trip and Reset settingis the differential. Figure 3-2Standard Contact Arrangement for Negative Pressure343.4.2 AdjustmentGenerally, unless otherwise specified, controls shipped from the factory are set at theoperating range vacuum indicated in Table 1-2 and minimum differential.3.4.3 Operating range adjustmentTurn range adjustment Screw A counterclockwise to lower the upper and lowervacuum settings.To increase the upper and lower settings, turn Screw A clockwise.The approximate upper vacuum setting is shown by indicators on the outer edges of thenameplate.3.4.4 Differential adjustmentWhen the differential blade is at the low point of the differential cam the control willfunction at minimum differential.To increase the differential, turn adjustment Screw Bcounterclockwise.This will decrease the higher vacuum setting only.To decrease thedifferential, turn differential adjustment Screw B clockwise.This will lower the highersetting only.Condensed instructions are supplied with open style controls and are on the inside of thecover on enclosed devices.NOTE: Use the vacuum gauge (See Figure 1-1) when setting the control.CAUTIONThe range adjustment Screw A should not be adjusted beyond thepressure indicated on the pressure scale as this may cause the control tomalfunction.It is recommended that a periodic inspection of gauge vacuum be made and the vacuumcontrol adjusted to compensate for application variables.35Section 4.0 Maintenance4.1 Service & PartsContact Siemens Vacuum Pumps directly at 513-841-3300 (or your local representative)for service assistance.Refer to Appendix for parts listing for your system.For sales or applications assistance visit our web site at www.siemensvpc.com and usethe interactive map in the contact section.4.2 Recommended Schedule of MaintenanceThe following schedule is a recommended guide based upon system operation undernormal conditions.The frequency of the maintenance intervals should be adjusted asrequired by the actual operating conditions.WEEKLY:Check all gauges to verify that they are reading within the specified ranges (seesection 1.2).Observe oil flow in the scavenging line.Check the system for any abnormal noise or vibration.Check for oil leaks.Check oil level.MONTHLY:Clean or replace inlet filter element (if applicable).Clean y-strainer screen.Visually inspect and clean entire system as required.Check for water in the separator, drain if necessary.EVERY THREE MONTHS OR 1000 HOURS OF OPERATION:Check coupling or pulleys for tightness on shaft.Check v-belt tension (if applicable).Check amperes draw for each motor.EVERY 18 MONTHS OR 10,000 HOURS OF OPERATION:Change seal oil using Siemens ELMO-Oil.Replace the coalescing filter in separator if backpressure is 3 psig.Replace coupling element or v-belts as required.Inspect and clean the scavenge line.EVERY 20,000 HOURS OF OPERATION:Replace the vacuum pump mechanical seals.Replace the vacuum pump bearings.36WARNINGShut down the system and lock out powerbefore proceeding with any of the scheduled maintenance.4.3 StrainerWith the pump shut down, close the ball valves located directly upstream and directlydownstream from the strainer.Place a catch pan directly below the strainer to catchescaping oil from the strainer and pipe (see Figure 4-1).With proper sized wrench,loosen the screen cover nut and remove (see Fig 4-2). Note that the stainless steel screenshould slide out easily. Remove the screen from the housing, clear any dirt or debris, andinspect screen for tears, old oil buildup or damage. After clearing the screen replace itand be sure that the screenslides easily back into place. Do not force the screw anchorsinto place; if resistance is felt, check the housing cavity for obstructions.Use Teflon tapeto reseal the threads of the strainer.Once the seal is re-established, be sure to open bothisolation valves to ensure proper operation of the system.Figure 4-1 Preparing to clean Y-strainer. Figure 4.2. Cleaning the Y-strainerscreen.4.4 Operating Liquid Seal OilThe ELMO-Pack TM Oil Seal System is shipped with factory recommended seal fluid. Werecommend the use of Siemens ELMO-22005G (See Appendix for MSDS Sheet) sealfluid to achieve optimum performance of the system.Contact the factory to reorder therequired replacement.37DANGEROperation on improperly selected oil can cause overheating,overloading of the motor or degradation of the elastomers used in thepump. Use only Siemens ELMO-22005G vacuum oil to preserve warrantycoverage.4.4.1 Draining OilPlace a catch pan under the ball valve located at the separator tank bottom (See Figure 4-3) With the pump shut down, open the ball valve and drain the operating liquid oil,emptying the catch pan to drain any water or dirt that may have accumulated in theseparator below the operating liquid outlet connection (See Table 2.1 for quantity of oilin system). When the oil has completely drained from the separator, shut the valve.Locate the system drain plug upstream from the thermostatic bypass valve in the verticalpiping tee (see Figure 4-4).Place a catch basin under the plug.Remove it and allow theoil to drain. After all the oil is completely drained reinstall the drain plug using Teflontape to assure a proper seal. Inspect used oil. If it seems dirty, flush the separator withclean oil as needed until the flushing oil runs clean.Properly dispose of the old oil.Figure 4-3.Draining the oil Figure 4-4.Using the total drainseparator. to remove all oil from the system.If removing the pump from the system, be sure to drain all of the oil from the casing.Todo this, locate the total drain on the bottom of the pump cover.Remove the drain plugand allow the oil to flow into a catch basin.Replace the total drain plug, along with thereusable gasket when finished.384.4.2 Adding oilWith the separator flushed, close the ball valve located at the tank bottom.Place oilabsorbent mats under the oil fill connection.Remove the square head pipe plug from theoil fill connection on the separator. Place the funnel in the fill connection opening andpour new oil into the separator.(See fig. 4-5) While adding oil check the level gaugelocated below the fill connection for oil level. Oil level must be maintained at the serviceliquid connection of the pump (models from 2 to 25 horsepower) or pump shaft centerline (models from 30 horsepower and higher) . Over filling will cause the pump tooverwork and become hot. After reaching the required level, (See Section 2.5, Table 2.1)operate the pump for 3 to 4 minutes.Now stop the pump and the check the oil levelagain. If required, add additional fluid up to the recommended level.Figure 4-5.Filling the separatorwith oil.CAUTIONDo not add oil through the gas discharge opening, sinceit will collect in the oil mist coalescing element and cause start-upproblems.Only add oil through the oil fill connection.4.5 Inlet Filter (optional)Check after 50 hours of pump operation, clean or replace the element every 1000 to 3000operating hours depending on the application or when excessive loss of vacuum isnoticed during operation. Be careful during inspection and cleaning not to knock offexcessive dirt or debris into the pump inlet. Remove any foreign debris from the filterhousing.FIRST TIME START-UPWhen starting a system for the firsttime after a rebuild of the pump or onreceipt from the factory, it may benecessary to prime the pump. See Section 2.5 for detailedinstructions.394.6 Discharge Oil Filter4.6.1 Removing FilterDisconnect and remove any discharge piping. Disconnect the scavenge line tubing at theconnection located below the in-line sight glass (Figure 4-6).Loosen & remove the hexbolts, hex nuts, and washers. Store the loose fasteners in a secure place. Place oilabsorbent mats around separator base to collect any excess oil in the discharge oil filterupon removal from the separator. Remove the separator top plate vertically being carefulnot to damage the internal scavenge line piping (Figure 4-7) Remove the internalscavenge line from the separator top plate to avoid damaging the piping while the filter isbeing replaced.Lift the filter vertically to avoid lodging the filter within the separatortank. Properly dispose of the old filter.Figure 4-6. Removal of separator lid.Figure 4-7. Removal of oilfilter.4.6.2 Replacing FilterWith the old filter removed per instructions above, place the new discharge oil filterinside the separator.If necessary, reconnect the internal scavenge line tubing to theseparator top plate.Orient the separator top plate so the external scavenge line realignswith the vertical scavenge line tubing from the pump and reinstall the top plate on theseparator. Replace hex bolts, hex nuts, and washers in the separator top plate and tighten.Reconnect the vertical scavenge line tubing from pump.404.7 CoolerThe air cooler should maintain a 150-190F pump discharge temperature. If thistemperature is not maintained, check the following:1.Fan motor not functioning (contact Siemens customer service for replacement.)2.Fan motor amps too high (check voltage).3. Visually inspect fan and radiator for any visible damage or wear.4. Clean Radiator fins as required if damaged, bent or clogged with debris.5. Oil flow blocked.Check y-strainer and clean as required.4.8 Inlet Check ValveIf an inlet check valve is replaced or reinstalled be sure that the valve is installed so theflaps fall downward. This check valve is provided without spring to assist close. Gravityholds the valve open when it is installed in the vertical position with flow downward.This valve should only close when the vacuum pump is de-energized and the process isstill under vacuum. The valve then closes and stops any flow of oil into the inlet pipingand the process equipment.4.9 Thermostatic Control ValveThe Thermostatic control valve is a non-adjustable valve. The valve comes factory set tooperate at 150F.When the discharge temperature gauge reads less than 150F, the linefrom the thermal bypass valve to the heat exchanger should be cool to the touch.Above150F, this line should feel hot.If this is not the case, contact a Siemens customerservice representative for a replacement.CAUTIONExercise care when touching piping with hot oil flowing inside.Do not touch if the discharge temperature gauge reads above 160 F, asburns may result.4.10 Pump Disassembly4.10.1 ApplicabilityThese instructions apply only to the 7.5 Horsepower through 25 horsepower model AV2ELMO-Pack TMsystems.For the systems below 7.5 horsepower consult the appropriateSiemens Manual for 2BV style pumps.For systems greater than 25 HP, consult theSiemens Manual for 2BE1 style pumps.Copies of these manuals are supplied whenapplicable or may be obtained directly from our website, www.siemensvpc.com.414.10.2 Removal of Pump from ELMO-Pack SystemsShut off and lock out the main power disconnects.Completely drain the oil from theELMO-Pack TM oil sealed system as described in Section 4.4.Disconnect and remove theoperating liquid piping, inlet piping and discharge piping from the pump/motor assembly.Using the illustrated lifting method (Figure 4-8), support the pump with an overheadcrane and remove the bolts holding the pump/motor assembly to the system frame.Pullout the pump/motor assembly and relocate it to a suitable work area.Figure 4-8. Proper lifting of the pump and motor assembly.4.10.3 Stabilizing the Assembly Prior to DisassemblyIt is recommended that the pump/motor assembly be held to the work surface with a C-clamp to avoid damage to the pump during disassembly or re-assembly.CAUTIONBe sure that the work surface chosen for the disassemblyand re-assembly can support the weight of the unit.424.10.4 Cover DisassemblyWith the pump secured to the working surface, locate the 5 hex bolts in the pump cover(Figure 4-9).Remove the bolts and pull the cover off of the pump.The cover alsocontains the port plate, which should only be removed from the cover if necessary (seeTrouble Shooting Guide, Section 6.0).Figure 4.9.Removal of pump cover. Figure 4.10.Removal of port plate from the cover.4.10.5 Removal of Port Plate from CoverWhen required, the port plate can be removed from the cover.Place the cover/port plateassembly on wooden blocks so that the port plate is laying flat parallel to the worksurface.Remove the total drain connection plug located at the bottom of the cover(Figure 4-10).Place a 3/8 diameter bolt (minimum 6 in length) through the total drainconnection and tap it with a hammer until the port plate comes loose from the cover.CAUTIONDo not apply excessive force when removing the port platefrom the casing as damage to the port plate could result.434.10.5.1 Removal of Seal Compound from Port Plate/Cover Surfaces.The port plate is sealed to the cover by application of a liquid sealant to the commonsurfaces on the reverse side of the port plate and the cover.Before re-assembly, oldliquid sealant (blue in color) should be removed from these surfaces with a putty knife orsuitable wire brush.During re-assembly, a liquid sealant must be reapplied to these samesurfaces any time that the port plate is removed from the casing.4.10.5.2 Variable Discharge Valve RemovalThere is a stainless steel plate bolted to the outboard side ofthe port plate at the discharge port (Figure 4-11).Removethis plate and the Teflon flapper valve found beneath it.Inspect the flapper valve for damage and replace asnecessary.4.10.6 Impeller RemovalUsing a slotted crossarm puller (Snap-On Model Number CJ84-4 or equal) and apneumatic wrench (Figure 4-12), pull the impeller off of the shaft (Figure 4-13).It ispermissible to heat the hub of the impeller when necessary.There is a fluted tolerance ring between the shaft and impeller that assists in holding theimpeller to the shaft.This ring should be replaced (do not re-use) during re-assembly ofthe pump.Now remove the key in the shaft and observe the mechanical seal.CAUTIONThe flapper valve must be installedfor proper operation of the pump.Operation without a flapper valve ora damaged flapper valvewill affect pump and systemperformance.Figure 4-11. Inside view ofport plate and cover.44CAUTIONReuse of the tolerance ring duringre-assembly may cause theimpeller to seat improperly ormove on the shaft, which coulddamage the pump.4.10.7 Mechanical Seal RemovalPlace some clean oil on the shaft to aid in removal of the mechanical seal.Slide themechanical seal out and off of the shaft.Place it in a clean area and protect the surfacesof the seal faces from damage.Figure 4-13.Removal of impellerwith slotted crossarm puller.454.10.8 Coupling RemovalAccess the coupling through the port in the side of the skirt.Loosen the setscrews andremove the coupling through the access port.4.10.9 Motor RemovalSupport the motor by using an overhead crane(Figure 4-14).Locate the four bolts holding themotor to the adapter plate.Remove the bolts andremove the motor from the work area.Figure 4-14.Removal of motor from pump pedestal.CAUTIONDo not operate the pump using motorsrunning at speeds other than those recommended by Siemens.Performance and system reliability will be affected.4.10.10 Shaft RemovalThe pedestal houses the shaft and two deep grooveball bearings.From the pump side of the pedestal,remove the v-ring and bearing cover.There aretwo shims under the bearing cover.Remove theseand store in a clean area (Figure 4-15).On themotor side of the shaft, remove the bearing coverand the compression washers.With both bearingsexposed, gently remove the shaft from thepedestal.Both bearings will be secured to theshaft.Figure 4-15.Bearing pedestalcomponents.464.10.11 Bearing RemovalUsing the bearing puller and a pneumatic wrench, remove both bearings from the shaft(Figure 4-16).4.10.12 Re-assemblyRe-assembly is the opposite of disassembly, with the following additional instructions.4.10.12.1 ClearancesWhen re-assembling the impeller to the shaft, use a feeler gauge to measure the clearancebetween the front face of the impeller and a metal straight edge placed against the face ofthe casing.Refer to Table 4-1 for required clearances.Table 4-1 Recommended clearances for 2AV2 pumps.HORSEPOWER MODEL CLEARANCE7.5 2AV211010 2AV211115 2AV212120 2AV213125 2AV2161.15 to .20 mm(.006 to .008 inches)Use the crossarm puller to re-assemble the impeller to the shaft.4.10.12.2 Seal of Port Plate to CasingApply liquid sealant to all common faces between the back of the port plate and the coverprior to re-assembly.Do not over apply sealant to assure proper operation of the pump.The recommended sealant is Dow Corning 832 or comparable.Figure 4-16.Bearing Removal from pump shaft.474.10.12.3 O-Ring ReplacementIt is often difficult to replace the o-ring located on the outside of the inner face of the portplate to seal it to the casing.To assist in placing the o-ring properly, it is permissible tospray the o-ring with adhesive (3M High Strength Binding Spray Adhesive or equal) toassist in re-assembly.4.11 Motor MaintenanceAt a minimum, the bearing lubrication, insulation resistance and cleanliness of the motormust be periodically checked as part of a routine maintenance program.4.11.1 Bearing LubricationCAUTIONDo not lubricate motor while in operation, since excess grease will beforced through the bearings and into the motor before it will force itsway out of the drain plug.Excess grease accumulation on windingsreduces insulation life.Bearing life is assured by maintaining proper alignment, proper belt tension, and goodlubrication at all times.Prior to shipment, motor bearings are lubricated with the proper amount and grade ofgrease to provide six months of satisfactory service under normal operation andconditions.For best results, grease should be compounded from a polyurea base and a good grade ofpetroleum oil.It should be of No. 2 consistency and stabilized against oxidation.Operating temperature range should be from 15F to +300F for class F and Hinsulation.Most leading oil companies have special bearing greases that are satisfactory,such as Exxon Unirex N3.Re-lubricate bearings every six months (more often if conditions require), as follows:1.Stop the motor.Lock out the switch.2.Thoroughly clean off pipe plugs and remove from housings.3.Remove hardened grease from drains with stiff wire or rod.4.Add new grease to inlet with hand gun until small amount of new grease isforced out of drain.5.Remove excess grease from ports, replace inlet plugs, and run motor hourbefore replacing drain plug.6.Put motor back into operation.484.11.2 Checking Insulation ResistanceCheck insulation resistance periodically.Any approved method of measuring insulationresistance may be used, provided the voltage across the insulation is at a sage value forthe type and condition of the insulation.A hand cranked megger of not over 500 volts isthe most convenient and safest method.Standards of the Institute of Electrical andElectronics Engineers, Inc. (IEEE) recommend that the insulation resistance of statorwindings at 75C, measured at 500 volts DC, after one minute should not be less than:Rated Voltage of Machine + 1000= Insulation Resistance in Megaohms 1000This formula is satisfactory for most checks.For more information, see IEEE StandardNo. 43, Recommended Practice for Insulation Resistance Testing of AC RotatingMachinery.4.11.3 Checking Motor CleanlinessCAUTIONDo not attempt to clean motor while it is operating.Contact withrotating parts can cause severe personal injury or property damage.Stop the motor and lock out switch before cleaning.The motor exterior must be kept free of oil, dust, dirt, water, and chemicals.For fancooled motors, it is particularly important to keep the air intake openings free of foreignmaterial.Do not block air outlet or inlet.On non-explosion-proof TEFC motors, a removable plug in the bottom center of themotor frame or housing permits removal of accumulated moisture.Drain regularly.494.12 V-Belt Drive InstructionsELMO-Pack systems utilizing a V-belt drive must be properly set up and positionedbefore stating.Sheaves must be aligned with the grooves parallel to each other.Setscrews and mounting bolts should be checked to ensure tightness on the motor andpump shafts.Ensure that sheaves are properly installed and aligned before tensioning thedrive.Belts should be placed over the sheaves and into the grooves without being forcedinto place.1.With all belts in their grooves, adjust the center distance and take up the slack untilthe belts are fairly taut (use the adjusting bolt on the motor slide base to perform thisoperation) with a slight bow on the slack side.2.Test the drive under load conditions.If the bow on the slack side is too tight or tooloose, shut down the unit and adjust the center distance accordingly.Retest the drive.Belts which slip or squeal on start are usually too slack, which results in inefficientoperation, high belt temperature and shortened belt service life.Belts which are tootight cause high motor amperage or excessive bearing load which may result inshortened bearing and shaft seal life.3.The belts should be monitored frequently for the first few days of operation.Thebelts will seat themselves in the grooves during this period.They may also stretch abit requiring some re-adjustment.NOTE:Belts should always be replaced as a set!Figure 4-17.Check individual unit rotation arrows to determine proper direction ofrotation.50Section 5.0 STORAGE5.1SHORT TERM (3 MONTHS OR LESS)The following steps must be followed:1. ELMO-Pack TM Oil Seal System must be stored in a warehouse free from extremetemperatures, humidity and corrosive atmospheres2. If unusual vibration exists at the storage facility isolator pads should be placed underthe ELMO-Pack TM Oil Seal System .3.All breathers and drains are to be sealed while in the storage facility to protect from moisture accumulation.4.Minimize condensation around the ELMO-Pack TM .Place desiccant around the motor and other controls to reduce the effect ofmoisture5.2LONG TERM (OVER 3 MONTHS)1. ELMO-PACK TM Oil Seal Systems are to be kept in a warehouse free from extremetemperature, humidity and corrosive atmospheres.2. If unusual vibration exists at the storage facility isolator pads should be placed underthe ELMO-Pack TM Oil Seal System.3. All breathers and drains are to be sealed while in the storage facility to protect frommoisture accumulation.4. Minimize condensation around the ELMO-Pack TM Oil Seal System. Place thedesiccant around the motor and other controls to reduce the effect of moisture.5. Coat all exposed machined surfaces with a material to prevent corrosion. (EXXONRust Ban #392, or equal)6. Before placing into storage, measure and record the electrical resistance of thewinding insulation with a megger or an insulation resistance meter. Minimumacceptable Megohm level is the insulation kV rating + 1 Megohm. This informationwill be needed when removing the system from long-term storage.7. When removing the ELMO-Pack TM Oil Seal System from long-term storage themotor windings are to be meggered and this reading is to be compared to with thereadings taken before the package was put into storage. The insulation resistancereading must not have dropped more than 50% from the original readings from line#6.Any drop below this point necessitates electrical or mechanical drying.51Section 6.0 Trouble ShootingACTIONS SYMPTOMSPump operates, but does not develop vacuumPump shuts down unexpectedlyPump overheats or operates above 200 FMotor kicks out after several startsPump will not startAbnormal noises or sound from pumpPump does not obtain desired vacuum levelExcessive vibrationExcessive oil usage or mistingPump will not rotateCheck inlet check valve and inlet filter (optional).Ensure no lines are open to atmosphere causing loss of vacuum.
