4) BASE FRAME

5) KIT FOR MOTOR ASSEMBLY

6) MOTOR/GEARBOX

7) FITTING CONNECTION

8) DAMPENER(OPTIONAL)

9) LEAK DETECTOR(OPTIONAL)

OPERATING PRINCIPLE C.2

In the peristaltic pump, an elastomeric tube (Tubular Element) is progressively C.2.1

crushed by the rollers. The alternation between compression and relaxation of the

hose generates continuous fluid suction and discharge.

Dry running, when the pump is empty, does not cause any damage.

Reverse flow by reversing motor

Flow rate proportional to rpm



WARNINGS C.3

The instructions given in this manual, whose failure causes a safety C.3.1hazard, are identified by this symbol

The instructions given in this manual that involve electrical safety hazard C.3.2are identified by this symbol

The instructions given in this manual that involve a potential mechanical C.3.3risk, are identified by this symbol

The instructions given in this manual that involve a potential compromise in C.3.4stated performance or intended functioning are marked with this symbol

GENERAL DESCRIPTION C.4

The moving mechanical parts are protected by guards (transparent cover and guide) C.4.1

which can only be removed with tools.

During use, all guards must be correctly secured and in place. C.4.2

The rotation of the rollers causing compression of the tubular element is dependent C.4.3

upon the guide and the transparent cover; the transparent cover must never be

separated from the guide during operation.

Failure of the tubular element due to fatigue or puncture will cause leakage of the C.4.4

pumped liquid.

The pump must NEVER be operated with a closed valve on discharge side of pump. C.4.5

Damage to pumping equipment will result.

When used with products or fluids suitable for consumption, the tubular element must C.4.6

be approved for contact with pumped product.

All operations requiring opening of the electrical control panel and/or opening of the C.4.7

motor terminal board box (electrical parts), must be carried out by trained personnel.

D INSTALLATION

INSTALLATION AND MAINTENANCE D.1

The machine must be positioned to adequate service access to the parts requiring routine maintenance, including inlet/outlet, leak detector, guide and cover. If equipment includes electric motor and or control panel or VFD, provide access as required by national electric code (NEC) or local regulations.

As a general rule, the installation should be in a well ventilated locaion away from D.1.1

sources of heat. If you need to place the pump outdoors, provide a suitable and

accessible enclosure to protect it from weather and direct sunlight. Freeze protection

and winterization must always be taken into consideration where applicable.

INSPECTION D.2

Once the machine is removed from its original packing, check the machine for any D.2.1

visible scratches or damage. When possible, recycle packaging material.

Prior to connecting to supply power, have an electrician confirm adequate electrical D.2.2

supply capacity. Check that the power supply is adequate to handle the load and that

the voltage and phase are correct.

Verify the inlet/outlet piping connections to be made at the pump. The piping must D.2.3

be at least the same size as or larger than the hose inside diameter.

Make sure that the type of tubular element that is suitable for the fluid to be pumped. D.2.4

If the fluid has a constant temperature above 60 ° C, the housing of the pump will

reach temperatures that make it dangerous to touch, therefore suitable warnings or

guards must be provided.

ELECTRICAL CONNECTION D.3

The electrical control panel or VFD panel must be adequately sized for motor loads. D.3.1

All wiring must be appropriately sized for the loads and distances.

If the control panel or VFD is remotely located, an electrical disconnect must be D.3.2

installed adjacent to the pump to facilitate service or maintenance.

All work involving electrical components must be performed with the machine at a D.3.3

standstill and disconnected from the main power supply.



PIPING D.4

INLET (suction): The pump must be as close as possible to the fluid source so that D.4.1

the inlet pipe is as short and as straight as possible. - All suction piping must be

perfectly airtight. It must be made of material that is rated for full vacuum and that is

compatible with the fluid being handled.

- The minimum diameter must be equal to the tubular element. - Viscous fluids require larger diameters. - The pump is self-priming, no foot valve is needed. - A properly sized vacuum dampener or inlet stabilizer is recommended for negative

suction lift applications to improve flow characteristics to the pump inlet.

OUTPUT (discharge): To reduce discharge pressures caused by friction loss, use D.4.2

pipes as short and as straight as possible. The diameter will be equal to the rated

pump diameter, unless specific calculations require otherwise. Viscous fluids require

larger diameters. The discharge line piping must be made of material that is

compatible with the fluid being handled and rated for a minimum of 1.5 times

maximum pump pressure.

- The minimum diameter must be equal to the tubular element. - Viscous fluids require larger diameters.

Always connect and support Inlet/Outlet piping at the pump and include a UNION or D.4.3

FLANGE to facilitate maintenance. Attach the pipes securely and avoid loads on the

pump or piping.

Installation of a flexible hose or coupling is recommended in applications where D.4.4

vibration can cause damage to piping or pump inlet/outlet. Low frequency pulsation

can be balanced with the use of pulsation dampeners or other pulsation dampening

components. Pulsation dampening is encouraged when pump speed is greater than

20 RPM or discharge pressures exceed 2 Bar.

The inlet and discharge flows will pulsate at a rate proportional to the speed (RPM) of D.4.5

the pump. The pulsation will be more pronounced as the speed of the pump

increases and/or the discharge pressure increase. If there is a risk of the pulsations

damaging the pipes or disturbing the utilities downstream, suitable pulsation

dampening will be required.

The pump is supplied with a stainless steel frame that must be bolted securely to the D.4.6

substructure. At startup and during regular maintenance intervals it is important to

periodically confirm all fasteners are secure. The pump may be supplied with an

optional wheel kit when pump mobility is required.



TYPICAL PIPE INSTALLATION D.5

OPTIMUM LAYOUT FOR FLUIDS: D.5.1

Minimize suction distance and vertical lift.

Where possible, orient the outlet piping to allow for draining.

LAYOUT FOR FLOODED SUCTION: D.5.2

Always install provided pump leak detector to alert in the case the tubular element breaks.

For corrosive or dangerous fluids provide with a secondary containment.

Always include shut off valve at pump inlet.

PRESSURE RELIEF D.5.3

If there is danger of a valve being shut on the outlet side of the pump, an appropriately sized pressure relief valve is required.

If the pump is reversed, the same danger can exist on the inlet piping in case of reverse flow.

PUMP AT A STANDSTILL: D.5.4

When vertical discharge head “H” is over 13 feet (4 meters), the fluid may cause the pump to rotate backwards, flowing back in the pipe towards the suction line.

Avoid this potential problem with a self-braking motor, variable frequency drive or single acting valve (check type valve).



E INSTRUCTIONS FOR STARTING - RUNNING - STOPPING

STARTING E.1

Before starting the pump, ensure that:

The type of tubular element is suitable for the fluid to be pumped. E.1.1

The power supply voltage corresponds to the motor voltage and electrical control E.1.2

panel voltage and phase.

Check that the guards are fitted around any moving parts. E.1.3

Check that the motor thermal protection is set to the values on the motor rating plate. E.1.4

Test to check the rotation, adjust motor leads or VFD to adjust direction. E.1.5

Confirm all electrical components are connected to the control panel and operation E.1.6

has been tested.

Verify discharge pressure is within pump operating capacity. Use a pressure gauge E.1.7

on the discharge line if any uncertainty exists.

RUNNING E.2

Set the rollers to the working position. E.2.1

Start the pump, ensure all valves open at operate at minimum speed (if adjustable). E.2.2

Start and stop the pump a few times to check operation of the controls and look for E.2.3

leaking pipes or system improper seal.

If there is the possibility of working with closed valves on the pressure side of the E.2.4

pump, test the safety devices (pressure relief valve) for proper functionality.

Using appropriate testing gauges (vacuum, pressure, flow meter, amp meter) confirm E.2.5

the pump is operating as intended and that the flow rate, pressure, and motor current

draw are appropriate for the application.

WHAT TO AVOID E.3

Do not change fluids being pumped without cleaning the fluid path, inside of the E.3.1

pump; the mixture of chemicals can be highly dangerous.

Never leave the pump full, particularly in case of the fluids that can deposit residues E.3.2

or polymerize, or corrosive fluids that can eventually attack the hose.

Do not increase the setting of the motor protections beyond the limits specified on the E.3.3

rating plate. If the motor performance is insufficient, check the system data and

contact technical support.

When cleaning the pump with pressurized water, do not direct it at the electric motor E.3.4

or electrical equipment.



STOPPING E.4

Switch the motor off to stop the flow. The pump operates similar to a pinch valve E.4.1

(compression of the hose) unless the pump is in the standstill position as described

in D.5.4.

To drain fluids from the tubular element, disconnect inlet and rotate pump to E.4.2

discharge fluids to discharge.

The piping and hose must be cleaned with fluids that are compatible with both the E.4.3

hose and the chemical being pumped”

For prolonged shutdowns, put the rollers in the rest position to avoid any damage to E.4.4

the tubular elements..

RESIDUAL RISK E.5

Use with foods: E.5.1

The pump can be used for food-grade fluids if tubular element is classified for

specific use with a food, see HOSE SELECTION GUIDE at the end of this manual.

Always use stainless steel fittings, and adequate cleaning (CIP/SIP) procedures

when handling food grade fluids.

It is not possible to accurately forecast the duration of the hose element; therefore, E.5.2

precautions for breakage with leakage of the liquid must be taken in advance. The

hose leak detector should be wired to stop the pump and to sound an alarm. If the

fluid is hazardous or can create dangerous fumes, the following must be addressed:

• Secondary containment. • Adequate ventilation and drainage.

CONFIGURATION E.6

The capacity of the pump and the ability to create discharge E.6.1

pressure depends on the compression of the hose by the

rollers

Two configurations are available for this model: • Shims marked "4" for pressure lower than 4 bar. • Shims marked "8" for pressure up to 8 bar.

The shim configuration is established at the factory when the E.6.2

pump is ordered. All subsequent variations must be

authorized by the technical staff at

Adjustment

Discharge piping

Suction piping

ATTENTION

Before opening the pump, ensure that the piping is empty. The pressure created by the fluid on the tubular could turn the rotor, creating a danger for the operator.

F MAINTENANCE

ALL WORKS ON THE PUMP MUST BE CARRIED OUT WITH THE MACHINE AT

STANDSTILL AND DISCONNECTED FROM THE MAINS

COMPONENTS SUBJECT TO NORMAL WEAR F.1

The only component subject to normal wear is the tubular F.1.1

element which therefore must be periodically replaced.

LUBRICATION F.2

The tubular element must be lubricated at initial assembly with silicon grease only. F.2.1

Periodically (approximately 100 working hours) check that the wall of the stator F.2.2

where the hose rests and ensure there is a light silicone lubrication. If necessary,

inject a small amount of grease lubricant at the top or side grease fitting (if available).

Five shots of grease from a standard grease gun is sufficient.

REPLACING OF THE TUBULAR ELEMENT F.3

Jog the rotor until one of the rollers is free of contact from the tubular element. F.3.1

Disconnect the main electrical power to the pump. F.3.2

Dismount the suction and discharge piping. F.3.3

INACTIVITY F.4

If the machine is inactive for more than 30 days, the operator should make sure that F.4.1

the tubular element is not unnecessarily stressed by setting the roller to the rest

position. This procedure will help to maximize the life expectancy of the tubular

element.

To do this you must put the roll in rest position; follow the F.4.2

procedure relating to the replacement of the tubular

element 5 point then:

Mount the support with roller (5) in the rotor in a central F.4.3

location.

Start and turn the rotor until the roller (6) is no longer in F.4.4

LEAK DETECTOR (OPTIONAL) F.6

The hose leak detector is a safety device that can be wired to stop the

motor or sound an alarm if the tubular element breaks and the fluid

leaks inside the pump housing.

The probe must be connected to an electrical panel as shown in the

diagram below in section F.6.2

It does not require any regular maintenance, however it is good

practice to periodically test the operation and ensure that the float is

free to move.

P TUBULAR ELEMENT

SELECTION CRITERIA P.1

The tubular element will dictate the performance and limitations of the peristaltic P.1.1

pump;

The proper selection depends on the following conditions:

Chemical compatibility;

Operating pressure;

Operating temperature;

RPM;

Suction capability;

Duty cycle;

Hose life expectations;

Compatibility with food products.

must be informed of the application when order is placed to ensure compatibility

1) Consider the dangers of handling aggressive chemicals (possible leaks)

Site specific conditions of temperature, pressure and chemical concentration of fluid

being pumped are all necessary to ensure compatibility.

2) If unsure of chemical compatibility, cut a small segment-sample of tubular element,

noting weight, length, and other physical characteristics. Soak for about 72 hours and

check any changes in color, size, weight, hardness, or other damage. If the sample

appears to be unaffected it should be safe to use in operation.

DISPOSING P.2

Depending on the fluid being pumped, the internal hose element, once used may be P.2.1

considered hazardous material. Contact your local waste disposal group to ensure

the material does not require special handling or disposal.
