Shutdown
Has the pump been exposed to condensate?
- Allow the pump to continue to run for a few minutes
with the rotary vane pump’s gas ballast valve open be-
fore switching off.
Long-term:
- Separate the pump from the application.
- Drain condensates (catchpots of the separator at the
inlet and of the oil mist filter).
- Flush the pump with dry nitrogen.
- Carry out oil change (see “Oil change”, pg. 32).
- Fill the pump completely with new oil (to above the
”max.” mark!).
Attention: Before restarting the pump, drain oil to the
maximum oil level (”max.” mark)!
- Close the manual gas ballast valve.
- Close inlet and outlet ports (e.g., with transport caps or
blind flanges).
- Store the pump under dry conditions.
- Carry out oil change and maintenance prior to use if the
pump has been stored for longer than one year.
Note: When transporting a pump containing oil, take great
care not to tilt the pump to an angle that would allow oil to
make its way into the filter element. Drain oil if necessary.
