7.2.2.2 Cleaning filters
CAUTION
Insufficient inlet pressure due to clogged filter in the suction line
Damage to the pump!
▷ Monitor contamination of filter with suitable means (e.g. differential pressure
gauge).
▷ Clean filter at appropriate intervals.
7.2.2.3 Lubrication of plain bearings
CAUTION
Pump set filled insufficiently
Lack of lubrication of product-lubricated plain bearings!
Dry running of the plain bearings!
▷ Monitor the pump set fill with a fill level monitoring device.
During operation the hydrodynamic plain bearings are lubricated by the fluid
handled or the barrier fluid. Bearings must be checked for wear in the following
cases:
▪
When the pump has been operated under dry-running or cavitation conditions,
the bearings should be checked immediately if possible.
▪
Vibrations, noise and an increase in current input occurring during unchanged
operating conditions indicate wear at the bearings (insufficient lubrication).
Also check the bearings in this case.
7.2.2.4 Checking the shaft seal (for models with leakage barrier only)
If a defect in the containment shroud (rare defect) results in leakage of a fluid whose
critical properties might pose a hazard to staff and the environment, the shaft seal of
the leakage barrier must be checked regularly.
