Abstract

The two-stage liquid ring pump (10) is built in block construction, with the pump casing (11) flanged directly on a drive motor (4) of bearing pedestal. The second working chamber (19) of the pump is rotationally offset in relation to the first working chamber (15), whereby a vector directed from the middle point of the first working chamber to the middle point of the drive shaft (21) is rotationally offset by an angle of preferably 195 degrees in relation to a vector directed from the middle point of the second working chamber to the middle point of the drive shaft.
