Rotary vane oil lubricated

BUSCH rotary vane oil lubricated pumps provide technically simple vacuum pump construction. A constant high vacuum level is ensured by well-coordinated materials and exceptionally high manufacturing precision with circular oil lubrication operation, maintaining high vacuum levels even during continuous operation.

The standard oil separator ensures oil-free exhaust thanks to an advanced extraction system with integrated oil return. When the ballast valve is open, it is also possible to release large amounts of vapor.

A non-return valve at the suction inlet prevents air from re-entering the vacuum chamber when the pump is turned off.
