1.1.4 Lubricants
RUVAC WS/WSU pumps are, as standard, prepared either for operation with
mineral oil, synthetic oil or the special lubricant perfluoropolyether PFPE).
Other types of oil (white oil, for example) upon request.
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 with mineral oil we recommend our vacuum pump oil
LVO 100.
When the RUVAC is operated at a pressure difference of Dp > 10 mbar or at
> 60 Hz.then LVO 210 should be used.
In case of operation with PFPE we recommend our LVO 400. PFPE pumps
are marked by an additional red label at the oil-fill screw.
1.2 Standard Specification
RUVAC WS/WSU are supplied for vertical flow.
Before delivery the oil has been drained out. The quantity of mineral oil,
synthetic oil or PFPE which is required for operation, is supplied separately
with the pump.
All pumps are equipped in their intake flange with an intake screen and have
been vented with nitrogen so as to protect the pump against corrosion. The
flanges are sealed by a zinc coated metal cover plate with polymer seal.
All pumps are equipped with a standard motor in accordance with the IEC
standard.
