Abstract

The pump has a control leakage shaft seal (12) surrounded by a seal space (13) through which a partial current of conveyed fluid flows. A circular gasket (14) is fixed on a shaft (5) in axial direction between a rotor (4) and the control leakage shaft seal. The gasket for the fluid partial current has an outlet (19) that is connected with an outlet channel (17) leading to a rotor inlet (6). The outlet is provided between the shaft and a central opening of the gasket.
