Durco PolyChem M-Seriessealless pumps are rugged,heavy-duty pumps designedspecifically for leak-free,reliable performance indemanding processapplications.

Worldwide ApplicationPolyChem is the result ofextensive market researchwith Flowserve customersaround the world. Pumpusers stated the PolyChempump must providereliability and value whilestandardizing on a commonglobal design.

Furthermore, customerswanted a choice of sealedor sealless designs andlined or solid non-metallicconstruction.

With the introduction ofPolyChem, these requestshave been fulfilled.

Only Durco Polychem offers anon-metallic pump with theadvantages of an oversizedseal chamber with flowmodifiers.

Seal life is extended due tosuperior purging of heat, solidsand vapors. Single seals canoften be selected where dualseals or external flush andthroat bushing combinationshave been used.

Flow Modifiers ExtendMechanical Seal MTBPM• Flow modifiers redirect flow

from circumferential to axial• Balanced flow with low

pressure drop in the chamberhelps keep solids insuspension, minimizingerosive characteristics of theprocess

• A mechanical seal creates acentrifuging action awayfrom its parts and into thereturning flow path of theprocess liquid

• Solids merge in thereturning flow pathand are flushed out ofthe seal chamber

• The high flow rateprevents suspendedsolids from precipitat-ing or crystallizing toseal or seal chamber.

Encapsulated PFA Impellerdesign provides highefficiency

Unique mechanical seal • Rotating seal face locked in

the back of the impeller• Massive portion of the seal

and springs are stationary inthe chamber which allowsthe seal to flex to matchshaft deflection

• Eliminates shaft fretting• Metal parts of seal are not

exposed to corrosiveprocess liquid

Enlarged space around sealarea between the impellerand the cover• Better circulation and seal

Flowserve is recognized for itsproud history of non-metallicpump developmentThe following pumps wereindustry firsts and are stillavailable today for specificprocess applications:

T-LineMolded PTFE and PFA pumpcomponents. ANSI dimensional.For more information, pleasesee Bulletin P-15-100.

E-Series Durcon is an epoxyresin, modified toprovide the optimumcombination of corrosionresistance and strength.For more information,please see Bulletin P-13-101.

The KW941Pump PowerMonitor monitors and displaysactual power to the pumpoffering simultaneous protectionfrom underload and overloadoperating conditions.

The KW941 helps to eliminatecostly downtime and expensivepump repairs caused by:• Dry running• Pump overloads• Cavitation• Blocked lines• Closed suction or

discharge valves• Excessive wear or rubbing

Broad application range• Works on all pumps

having steady (non-pulsating) loads: cen-trifugal; gear; turbine;ANSI; API; paper stock;sealed; mag drive;canned motor; self-priming

Easy installation• Simple wiring

procedure• Easily installed on

existing pumpinstallations

Easy setup & calibration• Settings controlled

from front panel pushbuttons; no internaladjustments, dipswitches orpotentiometers

• Large digital displayfor easy viewing andaccurate settings

• One step calibrationcan be performedwithout operatingpump. No need to runpump at off-operatingconditions to calibratepower monitor

• Settings can be viewedor adjusted duringnormal pump operation

• Adjustable start up delay timeris particularly useful in self-priming applications

• 4 to 20 milliamp analog outputfacilitates remote displays,operator interface and outputto PLC or DCS

• Two form C relay outputs forlow and high power trips.Outputs can be used to shutdown pump or trip alarms

• Automatic, manual andremote reset options forversatile operation

Premium features for reliable protection• Push buttons display

horsepower or kilowatts;automatic conversionwhen switching displays

• Adjustable low power andhigh power set pointsprotect pump fromunderload and overloadoperation. Alarms can betripped or pumps shutdown before damageoccurs

• Adjustable trip delaytimers filter out nuisancetrips caused by temporarypower fluctuations

By sensing power and not just amperes,linear measurements are obtained,eliminating unwanted nuisance trips.

Flowserve offers a familyof pre-engineered baseplatedesigns to extend MTBPMand reduce costs.

Reducing internal stressand vibration extendsMTBPM of pump/motorpackages.Pump users specify rigidbaseplate designs to:• Provide torsional lateral

and longitudinal rigidity• Improve vibration

dampening throughgreater mass and designstiffness

• Protect against transitdamage

• Resist twisting duringinstallation

• Maintain designed-inshaft alignment

• Reduce installation andshaft alignment time

• Reduce diaphragming orseparation from grout

• Improve pump/motor/seal MTBPM

• Reduce total life cyclepump/motor/seal costs

Flowserve recommends:• Reinforced baseplate

to extend MTBPM• Level screw inserts for

baseplates to be groutedto reduce cost and time


Featuring Durco’s SolidPolymer Concrete Polybase™and Polybloc™ AdjustmentSystemAvailable in three materialcombinations for broad rangecorrosion resistance.• ANSI and ISO standard

designs• Low installed cost

Polybloc™ – MotorMounting Block• Flatter and more repeatable

height tolerances than steel• Corrosion resistant• Superior vibration

dampening• Full foot support (no
