Types of rotary vane pumps and compressorsRotary vane vacuum pumps are available in single- and two-stage versions and can be operated with different types of lubrication or dry-running. In single-stage versions, compression is carried out once. In two-stage versions, the pumped medium is compressed again in a second stage to allow for higher vacuum levels.
Rotary vane compressors operate according to the same principle.
Oil helps seal the clearance between the vanes and the housing in R5, HUCKEPACK and ZEBRA vacuum pumps. SECO vacuum pumps and compressors use graphite dust for lubrication. This is created when the graphite vanes grind along the edge of the cylinder.
