ABSTRACT:
An inline centrifugal pump comprising a radial or semiaxial impeller. The rotational axis of the impeller is perpendicular to the flow axis of the connection pieces. A suction channel leading from the suction connection of the pump housing to the suction mouth of the impeller comprises, in the turning region, a conically tapering section which runs towards the suction mouth of the impeller. In this manner the efficiency of the pump can be improved.
