Abstract
A centrifugal pump assembly includes an electrical drive motor (), an impeller () which is driven by the drive motor and a pump casing () surrounds the impeller and including two branches (). A movable valve element () is arranged in the pump casing and is movable between two switching positions, in which the flow paths through the two branches () are opened to a different extent. The valve element () is configured and arranged in the pump casing () such that it separates a suction chamber () which is connected to a suction side of the impeller () from a delivery chamber () which is in connection with the delivery side of the impeller (). The valve element () is mechanically and/or hydraulically coupled to the drive motor () for at least a movement between the two switching positions.
