Abstract

Die Erfindung betrifft eine Pumpvorrichtung, mit einem Impeller (10a; 10c), der zur Förderung eines pumpbaren Mediums um eine Rotationsachse (11a; 11b; 11c) drehbar gelagert ist, mit einem Einlassgehäuse (12a), das einen dem Impeller (10a; 10c) vorgeschalteten Ansaugbereich (13a) aufspannt, und mit einem zumindest teilweise innerhalb des Ansaugbereichs (13a) angeordneten Strömungsleitelement (14a; 14b; 14c), das dazu vorgesehen ist, das in Richtung des Impellers (10a; 10c) strömende Medium zu führen. Es wird vorgeschlagen, dass das zumindest eine Strömungsleitelement (14a; 4b; 14c, 15c) zumindest teilweise in Form eines Ringsegments ausgebildet ist.
