<p>Screw type liquid ring pump including a pump housing (9) with an inlet part (3) and an outlet part (11) and an, inside the housing, rotating helical scr ew rotor (8). The rotor is connected with a shaft (7) which is commonly provide d for the shaft as well as a driving unit in the form of motor, preferably electric motor (2), whereby the pump (20) with the pump housing (9) represen ts an elongation of the motor (2) with the motor housing thus representing an integrated or one piece unit. The shaft sealing (22, 23) is provided wholly or partially in an annular space (24) provided within the rotor (8), whereby th e sealing at its one end is resting against an annular part (25) of the screw rotor provided in the annular space (24) between the rotor and the shaft, an d at its other end is tightly provided against an inwardly protruding part (21 ) at the outlet end of the pump</p> |
