Notes
Check fill level and refill lubricant if necessary.
Check the lubricant purity
(foaming in the lubricant reservoir).
Refill lubricant without forming bubbles. Re-
move contaminated lubricant.
Use only clean lubricant specified for the intended
purpose. Refill lubricant only via the strainer on the
pump.
Check that the bearings and friction points to be
lubricated receive adequate lubricant.
If the lubricant quantity differs from the
planned value, the lubricant quantity must be
adjusted by a specialist.
Inform the supervisor to clarify further steps.
Adjustment of the lubricant quantity must be
performed by a specialist and may require prior ap-
proval and subsequent documentation.
Inadequate lubrication indicates a defect in the
corresponding supply line on the centralized
lubrication system.
Inform the supervisor to clarify further steps to
rectify the defect. The system may need to be shut
down until the defect is rectified.
Check the operating temperature range.
Immediately notify the supervisor if the range
is exceeded.
Check the gerotor pump unit for changes in run-
ning noise and/or vibrations that occur.
Determine the cause; if necessary, have the
affected components (motor/coupling/pump)
replaced by SKF Service.
Inform the supervisor to clarify further steps to rec-
tify and clarify the defects. Shut down the system
until the defect is rectified.
Check that there is no contamination or dust
deposits.
If there is contamination or dust deposits, clean
the pump with a moist cloth. Do not stir up dust
in the process.
Check that there is no apparent:
○
Damage to cables, terminal boxes
○
Unusual noises, vibrations, moisture
accumulation, odors, smoke, scorched areas
○
Corrosion
Check that:
○
All lubrication lines, connections, etc. are
correctly installed, undamaged, and tight
○
All monitoring and additional equipment is
correctly connected and undamaged
○
Cooling fins on the electric motor are free of
contamination
○
The prescribed clearance between the electric
motor and the system environment still exists
○
Grounding strip(s) and protective earth con-
ductors are fully present, properly connected,
and electrically continuous.
Immediately inform the supervisor in case of
apparent deficiencies, defects, or deviations.
Inform the supervisor to clarify further steps to
rectify the defects. The system may need to be shut
down until the defect is rectified.
○
All warning labels on the product are present
and in proper condition.
Replace any defective of missing warning
labels.
○
Check the filters upstream or downstream of
the pump.
Clean upstream or downstream filters in good
time or on a regular basis.
Varnishing is fully present.
Replace/repair varnish on the gerotor pump
unit in accordance with ATEX requirements.
Pump motor bearings
- 4-pole motors at max.
40,000 operating hours
- 2-pole motors at max.
20,000 operating hours
Have the bearings or motor replaced by SKF
Service.
For further information, see the operating instruc-
tions from the motor manufacturer.
○
After completion of maintenance work.
Any dismantled protective and monitoring
equipment is fully reinstalled and functional.
After completing repairs, check compliance with the
requirements of a Notified Body in accordance with
Directives 2014/34/EU and 99/92/EC.
