Abstract
A centrifugal pump assembly includes an electrical drive motor (4, 6), an impeller (14) which is driven by the electrical drive motor (4, 6) as well as with at least one valve element (18) which is directly or indirectly movable along a first movement path between at least two switching positions, by the electrical drive motor (4, 6). At least a part of the valve element (18) is additionally movable along a second movement path which is different to the first movement path, between a released position, in which the valve element is distanced to at least one contact surface and a bearing position, in which the valve element bears on the at least one contact surface.
