4.2 Description
V-VC 40, V-VC 50, V-VC 75, V-VC 100 and V-VC 150 150 have a micro filter on the intake side and an oil and
oil mist separator for the return of the oil to the oil system on the outlet side. The vacuum pump is housed in
a sound cover. A fan between the pump housing and the motor cools the air in the pump housing and cools
the circulating oil.
An integral non-return valve prevents the evacuated system from being ventilated after the pump has
stopped. If the machine has been idle for more than two minutes the connected pipe should be ventilated to
atmospheric pressure.
A gas ballast valve fitted as standard (Fig. 2/U) prevents condensation of water vapour in the inside of the
pump when low amounts of steam are sucked in when the pump is at operating temperature. A reinforced
gas ballast (optional) can be used if there is a higher amount of water vapour.
The pumps are driven by standard flanged three-phase motors using a coupling.
Design „XD“: The functional parts are more resistant against water steam and solvents. In addition,
glass-fibre reinforced slide gates (GF) are used that are made of epoxy resin. The gas bal-
last quantity was increased.
Generally, the oil sump temperature was clearly increased compared with the standard
design.
Design „IV“: The pump is optimised to reach an increased final pressure and has no gas ballast valve.
This variant is especially suitable as backing pump for the operation of a booster pump.
