PUMP UNIT

A pump assembly includes an electric drive motor (4, 6), an impeller, driven by the drive motor (4, 6), and a valve device (18) situated in a flow path through the pump assembly, which is movable between a first and a second switching position. The valve device (18) is coupled to the drive motor via...

description	A pump assembly includes an electric drive motor (4, 6), an impeller, driven by the drive motor (4, 6), and a valve device (18) situated in a flow path through the pump assembly, which is movable between a first and a second switching position. The valve device (18) is coupled to the drive motor via a first coupling such that a movement of the drive motor (4, 6) is transmitted onto the valve device (18) and the valve device is movable from the first into the second switching position by rotation movement of the drive motor. The first coupling is releasable by way of increasing the speed of the drive motor (4, 6) and/or increasing the pressure at the outlet side of the impeller and/or by way of slip, such that the coupling between the drive motor (4, 6) and the valve device (18) is reduced or lifted.
