8.4 Oil check and oil change
Every 3000 operating hours or at least once a year,
change the oil in the oil chamber as described below.
If the shaft seal has been changed, change the oil as
well.
The table below states the quantity of oil in the oil
chamber.
Draining of oil
1. Loosen and remove both oil screws to allow all
the oil to drain from the chamber.
2. Check the oil for water and impurities. If the shaft
seal has been removed, the oil will give a good
indication of the condition of the shaft seal.
Oil filling, pump lying down
See fig. 11.
1. Place the pump in such a position that it is lying
on the stator housing and the outlet flange and
that the oil screws are pointing upwards.
2. Fill oil into the oil chamber through the upper hole
until it starts running out of the lower hole. The oil
level is now correct.
For oil quantity, see section 8.4 Oil check and oil
change.
3. Fit both oil screws using the gaskets included in
the O-ring service kit. See section 8.9 Service
kits.

change.
3. Fit both oil screws using the gaskets included in
