- we do not recommend an oil mist
eliminator when pumping condensable
vapors: if it is essential, do not connect
it directly to the pump exhaust but place
it outside the condensation zone.
- remove the stop valve from the pump
exhaust;
- if possible, connect the exhaust to a
mechanical device creating a negative
pressure from 0.1 to 0.2 bar.
- Valve off the pump from the system and increase the pump temperature,
30 minutes with gas ballast (see page 76).
- Start pumping and check the oil level:
• the level drops, oil is being lost;
• the level rises, condensates have been added to the oil.
- After pumping, regenerate the oil using gas ballast if it is cloudy or
discoloured.
• if the level is too high, change the oil and regenerate.
- Change the oil as soon as inlet pressure characteristics drop and are not
improved by regeneration.
