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.
