Liquid Ring Vacuum Pumps

Airtech liquid ring vacuum pumps and liquid ring compressors are rotating, non-pulsating, positive displacement pumps. Liquid ring vacuum pumps, also known as water ring vacuum pumps, contain a single moving part, the rotor. The rotor is located eccentrically within a cylindrical casing. Liquid is supplied to the pump and by centrifugal force, forms a liquid ring around the casing which results in the formation of compression chambers. Airtech provides both single stage and multi-stage liquid ring vacuum pumps in various materials of construction for a variety of applications.
