7. MAINTENACE AND REPAIRS
Please refer to paragraph of the instruction booklet for
information on maintenance and repairs.
In addition, the pump must never be cleaned using dry cloths
(rubbing with dry cloths made of pure polyamide material
or cotton, for example, can cause electric discharges).
Some pump models have a bearing on the joint. No
maintenance needs to be carried out on the bearings,
which should work for 10,000 hours at a temperature of
40°C without problems.
When replacing or controlling the bearings, the user must
contact the retailer or the help service.
The same is true for the seal (para. 6.2).
Verify, proportionally to the operation conditions, that the
compression ratio is lower than the spontaneous ignition
limit of the processed fluid.
Correct motor alignment is indispensable for preventing
vibrations and faulty bearings.
