Abstract (en)
[origin: WO2019175133A1] The invention relates to a centrifugal pump assembly comprising: an electric drive motor (2); at least one impeller (18) driven by said motor; and a pump housing (6) surrounding the impeller (18), said pump housing comprising at least one intake connection (20) and at least two pressure connections (22, 24), the pump housing (6) containing a rotatable valve element (30, 30', 30'') which can be moved between at least two selection positions in which the flow paths through the at least two pressure connections (22, 24) are open to differing extents. The valve element (30, 30', 30'') has an annular wall (32) surrounding the impeller (18), at least one selection opening (48) being formed in said wall, and the valve element (30, 30', 30'') is rotatably mounted in the interior of the pump housing (6) about an axis of rotation (X) that is central relative to the annular wall (32).
