Operating instructions
Mechanical seals
If the liquid being handled drips out at the mechanical seal, it is damaged and must be replaced.
Before opening the pump, it is essential that you note Point 1.4 „Safety
Instructions“, Point 4.8 „Dismantling“ and Point 8 „Repairs“.
Oil changing
(only with oil-lubricated pumps)
•
After the first 200 operating hours, drain off the oil (oil drains „AS“) and rinse with fresh oil.
Close oil drains „AS“ again and fill in oil at connections „FS“ (for all connections, see
„Summary of Screwed Connections“ in Appendix) in accordance with Point 2.3. Fill to level
described in Point 2.3.
•
After this, change oil every six months or every year (depends on air humidity).
•
If the pump is left idle for any length of time, the oil should be changed after two years.
•
For choice and quantity of oil, see Point 2.3 „Bearings and Lubrication“.
Old oil should be disposed of in accordance with the valid national environmental
regulations.
Grease lubrication
•
Bearings on pumps that are lubricated for life require no maintenance.
•
If the pump is left non-operational for any length of time, the grease in the bearings should be
changed after four years.
Couplings
Check the play in the coupling components regularly approx. every 1000 operating hours.
If wear is heavy, it must be assumed that the motor is not properly aligned with the
pump or that the distance between the coupling sections has changed.
Replace worn elements and re-install or adjust coupling, as described in Point 4.2.
Cleaning the pump
Dirt on the outside of the pump has an adverse effect on transmission of heat. The pump should
therefore be cleaned with water at regular intervals (depending on the degree of dirt).
The pump should not be cleaned with pressurised water - water will get into the
bearings
6. Longer periods of non-operation
After long stationary periods, packings may have hardened; these must be replaced
before start-up.
When starting up, follow the instructions for starting up for the first time (see Point
4.5)!
