Liquid Ring Vacuum Pumps

Liquid Ring Vacuum Pumps & Compressors

Liquid ring vacuum pumps normally operate with water as the operating medium. An eccentrically installed impeller rotates in the casing partly filled with liquid. By the rotational movement of the impeller and the resulting centrifugal force the liquid within the cylinder forms the so-called liquid ring.

Gas is conveyed in the spaces between the single vanes and the liquid ring. Due to the eccentric installation of the impeller the spaces enlarge and the process gas is sucked in through the suction intake. As the impeller further rotates, the spaces are reduced, so that the gas is compressed and discharged. The vacuum pump can be operated with water re-circulation, open or closed loop circuit.

Liquid ring vacuum pumps are available in one-stage or two-stage configurations, with both a close coupled and a base plate version. The proven compression principle allows them to be used in all sectors of industry. Critical applications such as evacuating saturated gases and vapors are easily carried out using liquid ring vacuum pumps.
