8. MAINTENANCE 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.
Verify, proportionally to the operation conditions,
that the compression ratio is lower than the spon-
taneous ignition limit of the processed fluid.
Correct motor alignment is indispensable for pre-
venting vibrations and faulty bearings.
