Abstract

Die Erfindung betrifft eine Kreiselpumpe, mit einem Gehäuse (20) und einem Laufrad (40), das auf einer in dem Gehäuse (20) drehbar gelagerten Antriebswelle (30) drehfest angebracht ist und das eine konzentrisch zu der Antriebswelle (30) angeordnete Scheibe (44) aufweist, auf der in Achsrichtung der Antriebswelle (30) weisende, radial verlaufende Flügel (46) vorgesehen sind, die zusammen mit den den Flügeln (46) der Scheibe (44) gegenüberliegenden Innenwandabschnitten (22a) des Gehäuses (20) Strömungskanäle für das zu pumpende Fluid bilden. Es ist ferner vorgesehen, daß an den radial verlaufenden Randkanten (46a) von vorzugsweise drei Flügeln (46) jeweils mindestens eine Erhebung (48) vorgesehen ist, die in Kontakt mit den den Flügeln (46) des Laufrads (40) gegenüberliegenden Innenwandabschnitten (22a) des Gehäuses (20) bringbar sind.

The invention relates to a centrifugal pump with a housing (20) and an impeller (40), which is mounted on a drive shaft (30) rotatably mounted in the housing (20) and which has a disk () arranged concentrically with the drive shaft (30). 44), on which in the axial direction of the drive shaft (30) pointing, radially extending vanes (46) are provided which, together with the inner wall sections (22a) of the housing (20) opposite the vanes (46) of the disk (44), provide flow channels for form the fluid to be pumped. It is further provided that at least one elevation (48) is provided on the radially extending edge edges (46a) of preferably three blades (46), which is in contact with the inner wall sections (22a.) Opposite the blades (46) of the impeller (40) ) of the housing (20) can be brought.
