INSTALLATION, TROUBLE-

SHOOTING AND MAINTENANCE

INSTALLATION

PIPING

Whenever possible ensure the pump is installed using

the shortest possible pipe lengths with the minimum

amount of pipe fittings. Ensure all piping is supported

independent of the pump.
Suction and discharge piping should not be smaller

than the connection size of the pump. When pumping

liquids of high viscosity, larger piping may be used, in

order to reduce frictional pipe loss.
Employ flexible hoses in order to eliminate the vibration

caused by the pump. Mounting feet can also be used to

reduce vibration effects.
All hoses should be reinforced, non-collapsible and be

capable of high vacuum service. Ensure that all piping

and hoses are chemically compatible with the process

and cleaning fluid.
For processes where pulsation effects should be

reduced, employ a pulsation dampener on the discharge

side of the pump.
For self-priming applications, ensure all connections

are airtight and the application is within the pumps

dry-lift capability. Refer to product specifications for

further details.
For flooded suction applications, install a gate valve

on the suction piping in order to facilitate service.
For unattended flooded suction operation, it is

recommended to pipe the exhaust air above the liquid

source. In the event of a diaphragm failure this will

reduce or eliminate the possibility of liquid discharging

through the exhaust onto the ground.

LOCATION

Ensure that the pump is installed in an accessible

location, in order to facilitate future service and

maintenance.

AIR

Ensure that the air supply is sufficient for the

volume of air required by the pump. Refer to product

specifications for further details. For reliable

operation, install a 5 micron air filter, air-valve and

pressure regulator. Do not exceed the pumps

maximum operating pressure of 120 psig.

REMOTE OPERATION

Utilize a three way solenoid valve for remote

operation. This ensures that air between the solenoid

and the pump is allowed to “bleed off,” ensuring

reliable operation. Liquid transfer volume is estimated

by multiplying displacement per stroke times the

number of strokes per minute

NOISE

Correct installation of the muffler reduces sound

levels. Refer to product specifications for

further details.

SUBMERGED OPERATION

For submersible operation, pipe the air exhaust to

atmosphere

GROUNDING THE PUMP

Loosen grounding screw and install a grounding wire.

Tighten grounding screw. Wire size should be a 12

gauge wire or larger. Connect the other end of the wire

to a true earth ground.
