Faults and Remedies



In case of a fault, stop the pump immediately!



Switch the plant into a voltage-free condition and secure against any unauthorized and
accidental restart!



After clearing the fault, inspect the pump and plant before putting the pump into operation
again!

Faults on pumps and pump units may be attributed to hydrodynamic, mechanical or electrical
causes. The following table shows a selection of possible faults.

8.1

Checklist for mechanical and hydrodynamic faults

Type of Fault

Possible Cause

Remedy

Pump does not start

Blockage caused by foreign matter Remove foreign matter

Deposits after shutdown

Immediately clean pump

Medium hardens

(due to temperature or chemical
conditions)

Solids contents is too high

Check

conveying conditions,

if necessary, change engineering data.

Stator swollen up

Check temperature of medium,

check resistance of stator elastomeric
relative to the medium.

Stator swollen due to excessive
loading.

Adjust pump operation time and cooling

time to speed.

Plant pressure too high

Compare pump nominal pressure to plant
conditions; if necessary, change
engineering data.

Pumping rate
decreases or is no
longer reached

Shutoff devices partially closed
blockage in the pipe

Fully open shutoff devices,

remove blockage.

Stator and/or rotor worn

Replace

Air locks in medium

Check intake pipe, media supply, and
seals.

Shaft seals are defective

Replace shaft seals.

Warning!

Rotating parts or pressurised spout liquids can cause fatal injuries.
Possible dangerous situation: Severe or fatal injuries!
