Contaminated pumps
CAUTION
Biological hazard
Minor or moderate
personal injury
- Flush the pump
thoroughly with clean
water and rinse the
pump parts in water
after dismantling.
Maintenance schedule
Inspect pumps running normal operation every 3000
operating hours or at least once a year. If the
dry-solids content of the pumped liquid is very high
or sandy, check the pump at shorter intervals.
Check the following points:
• Oil level and oil condition
When the pump is new or after replacement of
the shaft seal, check the oil level after one week
of operation.
Use Shell Ondina X420 oil or similar type.
• Cable entry
Make sure that the cable
entry is watertight and
that the cable is not
sharply bent and/or
pinched.

• Pump parts
Check the impeller, the pump housing, etc. for
possible wear. Replace defective parts.
• Ball bearings
Check the shaft for noisy or heavy operation by
turning the shaft by hand. Replace defective ball
bearings.
A general overhaul of the pump is usually
required in case of defective ball bearings or poor
motor function. This work must be carried out by
Grundfos or a service workshop authorised by
Grundfos.
• Grinder system and parts
In case of frequent choke-ups, check the grinder
system for visible wear. When worn, the edges of
the grinding parts are round and worn. Compare
with a new grinder system.
Oil check and oil change
Every 3000 operating hours or at least once a year,
change the oil in the oil chamber as described below.
If the shaft seal has been changed, change the oil as
well.
The table below states the quantity of oil in the oil
chamber:
