Maintenance and Servicing
Procedure
After the rotary vane pump has been filled with fresh oil, allow it to warm up by running it with
the suction port closed.
Drain the flushing oil. If the oil still appears heavily contaminated, the flushing procedure
must be repeated.
6.2.1.3 Changing the oil type
The vacuum pump is tested and supplied with
LABOVAC 10
mineral oil as standard.
If you want to use another type of oil, please note the following:
Compatible oils
Mineral oils may be exchanged among each other:
•
Drain the oil
•
Flush the vacuum pump with new oil
•
Fill the vacuum pump with new oil
Replacing a synthetic oil by a mineral oil is performed in the same manner.
Non-compatible oils
These oils cannot replace each other, that is they cannot be mixed.
LABOVAC 10
and
LABOVAC 13
are examples which can be named here. Even complete
disassembly and cleaning of the vacuum pump always involves the risk of small quantities of
oil remaining. We therefore recommend asking the manufacturer directly about vacuum
pumps with a special oil filling, for example
LABOVAC 13
.
