TYPES OF LIQUID RING VACUUM PUMPS
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.Depending on the pumped medium, liquid ring vacuum pumps can be operated as a simple continuous flow system or as a partial or total recirculation system.
The operating fluid is usually water, but other liquids may be used if required to suit the process conditions.
