Abstract
Gegenstand der Erfindung ist eine Kreiselpumpe mit einem Pumpengehäuse (1), wobei in dem Pumpengehäuse (1) ein Laufrad (2) und ein eine Saugöffnung ausbildender und in eine Bodenplatte (3) des Pumpengehäuses einsetzbarer Saugstutzen (4) angeordnet sind, der Saugstutzen (4) auf der Bodenplatte (3) des Pumpengehäuses dadurch axial ver- schiebbar gelagert ist, dass der Saugstutzen (4) und die Bodenplatte (3) jeweils wenigs- tens eine gegenüber der Bodenplatte (3) verschwenkte und aneinander anliegende Fläche (6) aufweisen, so dass durch Verdrehen des Saugstutzens (4) ein Abstand zwischen dem Laufrad (2) und dem Saugstutzen (4) veränderbar ist, und/oder an einer radialen Umfangsfläche (12) des Saugstutzens (4) ein im eingesetzten Zustand an der Bodenplatte (3) anliegender Dichtungsbund (14) vorgesehen ist.The invention relates to a centrifugal pump with a pump housing (1), an impeller (2) and a suction nozzle (4) forming a suction opening and insertable into a base plate (3) of the pump housing being arranged in the pump housing (1), the suction nozzle ( 4) is mounted axially displaceably on the base plate (3) of the pump housing in that the suction nozzle (4) and the base plate (3) each have at least one surface (6) pivoted relative to the base plate (3) and resting against one another so that by turning the suction nozzle (4) a distance between the impeller (2) and the suction nozzle (4) can be changed, and / or on a radial circumferential surface (12) of the suction nozzle (4) in the inserted state on the base plate ( 3) adjoining sealing collar (14) is provided.
