Liquid Ring Vacuum Pumps, using liquid to create the seal for vacuum generation
Single Stage with suction volume 2 – 370 m3/hr. Suction pressure: 33 mbar abs
Double Stage with suction volume 21 – 1600 m3/hr. Suction pressure 33 mbar abs
Liquid ring vacuum pumps are displacement pumps of robust construction. During operation the pump must be continuously supplied with service liquid, typically water, in order to eliminate the heat generated from the gas compression. These pumps operate either on a once-through principle or total liquid recirculation.
