6. MAINTENANCE AND REPAIR
DISCONNECT THE PUMP BEFORE ANY INTERVEN-
TION !
After an operation time of six to twelve months, the oil storage inside
the seal carrier always has to be controlled as follows:
- put the pump on its side on a clean surface and position it in such a
way that the oil filling screw faces upwards,
- take out the screw and check the oil level.
If only a small quantity of oil is lacking, the oil storage can be filled
up without any problems. If a considerable quantity of oil is lacking,
or if the oil is mingled with water, the customer department has to
be informed.
All other maintenance works on the pump and on the electrical
equipment should be carried out by the manufacturer or an autho-
rised qualified company in intervals of six to twelve months (or also
in shorter intervals, according to case of operation). Please immedia-
tely inform the customer department in case of damage to the pump
and/or the electrical equipment.
