CAUTION
Unsuitable time for flushing with oil
Damage to the bearings!
▷
Do not perform oil flushing of the oil lines until immediately before
commissioning/start-up.
▷
If commissioning/start-up is delayed by more than one month, repeat the oil
flushing.
General information
▪
During operation, the oil level in the bearing housing drops.
▪ An excessive oil level leads to a temperature rise and to leakage of the fluid
handled or oil.
▪ An inadequate oil level results in insufficient lubrication and bearing damage.
▪ Refer to the technical specifications section for the oil quantity/quality.
▪ Filter the oil prior to filling it in; filter mesh size 30 µm.
▪
After a standstill of more than 12 months, check the quality of the oil. Clean or
replace the oil if necessary.
▪
Fill the pump set components with lubricant in accordance with the
manufacturer’s product literature.
▪
Observe the permissible ambient temperatures. ( ð Section 6.6.2, Page 65)
For recommended oil quality, oil quantity and oil change intervals refer to:

6.2.5.1 Constant level oiler
Fig. 26: Constant level oiler
ü The constant level oiler is fitted in the bearing housing on the relevant side (see
figure Constant level oiler).
1. Remove breather diaphragm 823 with gasket 400.
2. Press together clamp on constant level oiler 638 and pull the reservoir of the
constant level oiler upwards.
3. Fill the reservoir of constant level oiler 638 with oil and return it to its operating
position.
4. Re-insert breather diaphragm 823 with gasket 400.
5. After a short time check whether the oil level in the reservoir has dropped.
It is important to keep at least one third of the reservoir filled at all times. If the
oil level is too low, top it up with oil.
