ABSTRACT:
To decrease gas leakage across the cantilevered axial end of the hub of a liquid ring pump rotor which has a central recess in that end of the hub, the adjacent port structure is provided with a protrusion which extends axially part way into the recess in the rotor hub. A relatively small clearance is provided between the radially outer surface of the protrusion and the radially adjacent inner surface of the recess. This clearance is filled with liquid and thereby increases the area of the seal at the adjacent axial end of the rotor hub.
