Abstract (en)
[origin: WO2018166967A1] The invention relates to a centrifugal pump aggregate having an electric drive motor (4, 6), an impeller (14) driven by said motor and at least one valve element (18), which can be moved by the electric drive motor (4, 6) directly or indirectly along a first movement path between at least two switch positions, wherein at least one part of the valve element (18) can additionally be moved along a second movement path, which differs from the first movement path, between a released position, in which the valve element is spaced at a distance from at least one contact surface, and a contact position, in which the valve element sits against the at least one contact surface.
