Busch Liquid Ring Vacuum Pumps
Liquid Ring
Liquid ring pumps are available in single- and two-stage versions. In single-stage versions, compression is carried out once. In two-stage versions, the pumped medium is compressed again to allow higher vacuum levels to be achieved. Operation as a compressor is also possible with some models of liquid ring vacuum pumps.
The operating fluid is usually water, but other liquids may be used if required to suit the process conditions.

Busch Oil-lubricated rotary vane vacuum pumps
Oil-lubricated rotary vane vacuum pumps
Rotary 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.
