Abstract

Die Erfindung betrifft eine Kreiselpumpe (1) mit einem Pumpengehäuse (9), in dem ein Pumpenlaufrad (13) in einem Laufradraum (12) umläuft, welcher von einem Spiralraum (15) umgeben ist, wobei in das Pumpengehäuse (9) mindestens ein Magnet (19) integriert ist, der in einem Bereich (20) angeordnet ist, der unmittelbar oder mittelbar an den Laufradraum (12) und/oder an den Spiralraum (15) und/oder an einen zwischen dem Spiralraum (15) und dem Laufradraum (12) befindlichen Ringraum (16) angrenzt. Die Pumpe ist vorzugsweise eine Spaltrohrpumpe (1) und der Magnet (19) kann vorteilhafterweise zugleich Bestandteil einer magnetischen Lagerung (19, 22) des Rotors (3) sein.

The invention relates to a centrifugal pump (1) with a pump housing (9), in which a pump impeller (13) rotates in an impeller space (12) which is surrounded by a spiral space (15), with at least one magnet in the pump housing (9) (19) is integrated, which is arranged in a region (20) which is directly or indirectly connected to the impeller chamber (12) and / or to the spiral chamber (15) and / or to one between the spiral chamber (15) and the impeller chamber ( 12) located annular space (16) adjoins. The pump is preferably a canned pump (1) and the magnet (19) can advantageously also be part of a magnetic bearing (19, 22) of the rotor (3).
