Abstract: An electric pump drive motor three-phase stator assembly (1) includes three sets of stator segments (Si,j), configured in a ring about a stator axis (R). Each set includes n≥2 stator segments arranged in an n-fold rotational symmetry about the stator axis. Each stator segment includes a coil (3) having a first coil wire end and a second coil wire end. A plurality of 3n−3 connection wires (Wi,k) connect coils of a respective set of stator segments in series. A first and a second interposed stator segment are arranged in circumferential direction between the two connected coils of the respective set of stator segments. 3n−5 of the connection wires span across the first interposed stator segment at a distance (r1) to the stator axis and across the second interposed stator segment at a second distance (r2) to the stator axis (R). The second distance is larger than the first distance.

The valve opening (41), the valve seat (43) and the valve body (45) define a common valve axis (47) extending transversely to the primary flow direction. An operating element (49), arranged at the pipe section opposite the valve opening, is configured to control the valve body for operating in a check-valve mode to open the valve opening upon a fluid flow from the valve opening towards the valve body and for operating in a shut off-valve to close the valve opening for any fluid flow direction.

Abstract: A pump assembly includes an electric drive motor with a motor drive shaft and a rotor. The motor drive shaft extends along a rotor axis and the rotor is mechanically coupled to the motor drive shaft. A pump housing encloses an impeller that is mechanically coupled to a pump drive shaft. The pump drive shaft extends along the rotor axis. The motor drive shaft is releasably coupled to the pump drive shaft by a drive shaft coupling for transferring torque from the motor drive shaft to the pump drive shaft. The drive shaft coupling is arranged within the motor drive shaft for transferring torque from the motor drive shaft to the pump drive shaft by frictional connection. The drive shaft coupling is accessible by an elongate tool through the second axial hollow motor drive shaft drive end for selectively tightening and releasing the drive shaft coupling.
