Pfeiffer DuoVane series rotary vane pumps are two-stage, oil-sealed rotary displacement pumps for use in coarse and medium vacuum applications. The rotary vane pump is available in the standard version with claw coupling and asynchronous motor.
Pfeiffer Vacuum DuoVane Line is the latest and the newest design within rotary vane pumps, with outstanding pumping performance.
The Pfeiffer Vacuum DuoVane 70 rotary vane pump is an oil-sealed rotary displacement pump. It includes air cooling and pressure oil lubrication. The pumping system comprises the housing, the eccentrically mounted rotor, and the centrifugal and spring-loaded radially sliding vanes, which divide the suction chamber into multiple chambers.
The volume of each stator chamber changes periodically as the rotor rotates. This causes the gas to be drawn in at the vacuum flange, and compressed in the suction chamber by the rotation of the rotor until the exhaust valve opens against the atmospheric pressure at the outlet and expels the gas. The exhaust valve is oil-sealed. When the valve opens, a small quantity of oil penetrates into the suction chamber. In addition to lubrication, this also causes the gaps between the rotor, stator, and vanes to seal.
