Abstract

Das Kreiselpumpenaggregat umfaßt eine elektrische Motorbaueinheit (2) und eine davon angetriebene Kreiselpumpe (3) mit einem Kreiselrad (7) und einem dieses umgebenden Gehäuse (8). Die Motorbaueinheit trägt das Kreiselrad der Pumpe und weist mindestens ein Wandteil (5) für das Pumpengehäuse auf. Der übrige Aufbau des Pumpengehäuses (8) ist über mindestens ein klemmendes Spann- und Halteelement (15) lösbar mit dem Wandteil der Motorbaueinheit (2) für das Pumpengehäuse verbunden.

Figure 00000001
The centrifugal pump unit comprises an electric motor unit (2) and a centrifugal pump (3) driven thereby with a centrifugal wheel (7) and a housing (8) surrounding it. The motor unit carries the impeller of the pump and has at least one wall part (5) for the pump housing. The remaining structure of the pump housing (8) is detachably connected to the wall part of the motor assembly (2) for the pump housing via at least one clamping tensioning and holding element (15).
