Draining the lubricant
Fig. 14: Draining the lubricant
1. Position the pump set as shown.
2. Place a suitable container under the screw plug.
WARNING
Excess pressure in the lubricant reservoir
Liquid spurting out when the lubricant reservoir is opened at operating
temperature!
▷ Open the screw plug of the lubricant reservoir very carefully.
3. Undo screw plug 903 with joint ring 411 and drain off the lubricant.
NOTE
Paraffin oil is bright and transparent in appearance. A slight discolouration, caused
by the running-in process of new mechanical seals or small amounts of leakage
from the fluid handled, has no detrimental effect. However, if the lubricant is
severely contaminated by the fluid handled, this suggests a defect at the
mechanical seals.
Filling in the lubricant
