Pay attention to possible faults.
Study the instructions carefully.
NOTE!
Study the maintenance instructions carefully before replacing worn parts. - See section 4.1
Problem
Overloaded motor
Cavitation:
- Damage
- Pressure reduction (sometimes to
zero)
- Increasing of the noise level
Leaking shaft seal
Leaking seals
Cause/result
- Pumping of viscous liquids
- Pumping of liquids with high
density
- Low outlet pressure (counter pres-
sure)
- Lamination of precipitates from the
liquid
- Low inlet pressure
- High liquid temperature
- Dry run (See operation/control)
- Incorrect rubber grade
- Abrasive particles in the liquid
Incorrect rubber grade
Remedy
- Larger motor or smaller impeller
- Higher counter pressure (throttling)
- Frequent cleaning
- Increase the inlet pressure
- Reduce the liquid temperature
- Reduce the pressure drop before the
pump
- Reduce speed
Replace:
All wearing parts (See general
maintenance)
If necessary:
- Change rubber grade
- Select stationary and rotating seal ring
in Silicon Carbide/Silicon Carbide
Change rubber grade
