Rotary vane vacuum pumps - Pfeiffer Vacuum

Pump oil, which is also referred to as operating fluid, has multiple tasks to perform in a rotary vane pump. It lubricates all moving parts, fills both the dead volume under the outlet valve as well as the narrow gap between the inlet and outlet. It compresses the gap between the vanes and the working chamber and additionally...

Rotary vane pump - Wikipedia

Rotary-vane pumps are also a common type of vacuum pump, with two-stage pumps able to reach pressures well below 10−6 bar. These vacuum pumps are found in numerous applications, such as providing braking assistance in large trucks and diesel-powered passenger cars (whose engines do not generate intake...
