4.4 Description
The C-VLR xx2 type with passive cooling is a double shaft rotary piston vacuum pump in which the claws
roll off against each other contact free and dry. The counter-rotating claw rotors are synchronised by a gear
pair in the gearbox. The gears of the synchronized gearbox and the bearings are lubricated with oil. These
components are in a gear case that also contains the oil supply. Oil conveying device always ensures that
the bearings and the gears are sufficiently supplied with oil at all permissible speeds. The gearbox and the
compression chamber are separated from each other by special seals.
It is driven via a coupling by a flanged, three-phase standard motor.
The VLR xx2 has a connection flange on the inlet side and an exhaust silencer on the pressure side
(Fig. 2- 3/Z). An integral non-return valve prevents the evacuated system from being ventilated after the
pump has stopped. This non-return valve includes a mesh filter to avoid damages due to pollution. A vacu-
um relief valve is incorporated into the machine.
