Disclosed is a liquid ring pump with one or several stages, each of which comprises a working chamber, an impeller that is eccentrically mounted therein, flat control disks that axially delimit the working chamber on both sides, and ducts or chambers that are located adjacent to the control disks and deliver and discharge the transport gas to and from the working chamber. The inventive liquid ring pump is characterized in that the control disks are embodied in the same manner with identical suction ports and pressure ports while ports that are not needed are covered on the side facing away from the impeller.

Liquid ring pump

A liquid ring pump comprises a first housing part that radially encloses two or more working chambers in which a rotatably mounted impeller is disposed in an eccentric manner, second and third housing parts that seal both sides of the first housing part and the pump, ducts or chambers for delivering and discharging the conveyed gas, and control disks that delimit the working chambers in an axial direction. The first housing part is embodied as a single piece while a connecting duct is provided which extends from the second to the third housing parts, and the ports facing the respective adjacent housing parts are configured such that the second and third housing parts can be embodied in an identical manner.
