1.2 Lubricants
The standard TRIVAC BCS pumps are either ready for operation with mineral oil
or with the special lubricant, perfluoropolyther (PFPE).
If mineral oil and PFPE come into contact they will emulsify. That’s why the
pumps must only be run with the type of lubricant specified for the pump. If you
want to change the type of lubricant Leybold should do the change.
In case of operation of a TRIVAC BCS we instruct our vacuum pump oil
LVO 100.
In case of operation of a TRIVAC BCS-PFPE we instruct our vacuum pump oil
LVO 400.
