The pump will have to be disassembled if there is more extensive contamina-
tion. The Leybold Customer Service Department will have to be consulted
here in all cases.
5.2 Oil of the Rotary Vane Pump
The TRIVAC or SOGEVAC requires for proper operation sufficiently fresh and
suitable oil.
The oil level of the backing pump must be checked at least once a week.
The oil must be changed when appears contaminated, chemically changed
or mechanically worn out. When the oil contaminates too rapidly, install a
dust and/or an oil filter.
Precise information on this topic and on other maintenance works is provided
in the Operating Instructions for the rotary vane pump.
With the gas ballast valve open, a larger quantity of oil escapes from the rota-
ry vane pump so that the oil level will have to be checked more frequently
under such operating conditions.
5.3 Removing the Backing pump
Each foot on the backing pump is bolted to the base plate by a bolt and
three nuts. The nut accessible from above is bonded to the bolt; the two nuts
accessible from below are counter-tightened.
To remove the backing pump, un-screw the counter-tightened nuts beneath
the base plate, and lift off the pump.
After removing the backing pump, seal both connecting flanges.
