Read the maintenance instructions carefully before replacing worn parts.

Problem

Cause/result

Remedy

Overloaded motor

-

Pumping of viscous liquids

-

Larger motor or smaller impeller

-

Pumping of high density liquids

-

Low outlet pressure (counter pressure) -

Higher counter pressure (throttling)

-

Lamination of precipitates from the
liquid

-

Frequent cleaning

Cavitation:
-

Damage

-

Low inlet pressure

-

Increase the inlet pressure

-

Pressure reduction (sometimes to
zero)

-

High liquid temperature

-

Reduce the liquid temperature

-

Increase in the noise level

-

Reduce the pressure drop before the
pump

-

Reduce speed

Leaking shaft seal

-

Running dry

Replace:
All wearing parts

-

Incorrect rubber grade

If necessary:
-

Change rubber grade

-

Abrasive particles in the liquid

-

Select stationary and rotating seal ring
in silicon carbide/silicon carbide

Leaking O-ring seals

Incorrect rubber grade

Change rubber grade
