Liquid Ring Vacuum Systems

Liquid ring vacuum pumps handle high volumes of vapours, condensables and liquids without affecting performance or reliability. The service liquid – water or other liquids, oils or solvents – can be selected to suit almost any application. Available in single and two-stage units.


Complete vacuum systems include a liquid ring vacuum pump, an air-liquid cyclone separator and a heat exchanger, all mounted on a compact skid for easy installation. For water-based applications, the system can also be configured to operate as a compressor, delivering pressures of up to 2 bar with optional upgrades
