Abstract (en)

[origin: US2018010609A1] A pump assembly includes pump casing (2), an impeller (14) rotatably arranged in the pump casing, a two rotation directions (A, B) electrical drive motor connected to drive the impeller and a valve arrangement (28) arranged in the pump casing to switch a flow path downstream of the impeller between two exits (24, 26) of the pump casing, depending on a rotation direction of the impeller. The valve arrangement includes a first movable valve element (34) at a first exit (24) and a second movable valve element (36) at a second exit (26). The first valve element partly closes the first exit in a closed position and is movable into an opened position by flow in the first rotation direction and the second valve element partly closes the second exit in a closed position and is movable into an opened position by flow in the second rotation direction (B).
