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.

- 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.
