Rotary Pump Oil
The oil in the rotary pump should be maintained at the correct level at all times.
Check the oil level at weekly intervals, topping up if necessary.
It is important to monitor the condition of the oil regularly. Replace the oil when it has
changed to a noticeable red colour, or routinely at 4 month intervals (3000 hours
operation). At the same time, replace the oil mist filter’s mist element (see above).
Change the oil in the rotary pump as follows:
Gas ballast lightly for 30 to 60 minutes.
Close the gas ballast valve.
Vent and shut down the instrument as described in Routine Procedures .
It is easier to drain the oil while the pump is still warm.
Drain the oil through the drain hole situated near the oil level sight glass.
Flush the pump, then replace the drain plug and refill the pump with the correct
grade oil to the correct level.
Gas ballast lightly for 30 to 60 minutes.
For further servicing information refer to the manufacturer’s manual.
