Abstract
The invention relates to a centrifugal pump assembly having an electric drive motor (2), at least one impeller (14) driven by said electric drive motor (2) and a valve element (24; 24′) rotatable between two 5 valve positions driven by a fluid flow produced by said impeller (14), wherein the valve element (24; 24′) has a cover plate (104; 104′) extending transverse to the rotational axis (X) of the impeller (14) and facing the impeller (14), wherein the valve element (24; 24′) having protrusions (102, 102′) arranged on an outer surface side facing away 10 from the impeller (14) such that a flow can act on them for driving the valve element (24; 24′).
