Abstract
An assembly, consisting of a motor and a pump, the motor being arranged in a motor housing and the pump in a pump housing. Both housings can be coupled to each other. The motor housing is provided with a second main bearing. The pump housing is equipped with a pump bearing. During normal operation, the forces acting on the pump eccentric are essentially supported by the main bearing and the pump bearing. The bearing forces are introduced into the pump housing. If the motor housing is not fastened to the pump housing, the rotor shaft is supported by the main bearing and, if necessary, an accessory bearing. Thus the motor can be tested without being connected to the pump housing.
