Abstract

Die Erfindung betrifft eine Pumpe, insbesondere Kreiselpumpe (1), mit einem Pumpengehäuse (2), wobei sich eine Motorwelle (5), die mit einem im Pumpengehäuse (2) angeordneten Pumpenlaufrad (6) verbunden ist, durch einen Wellendurchgang (4) in einer Rückwand (3) des Pumpengehäuses (2) erstreckt und in der Rückwand (3) mit einer Gleitringdichtungsanordnung (8) gelagert ist.
Um eine hohe Passgenauigkeit eines Dichtungssitzes auch über eine lange Lebensdauer zu gewährleisten, ist der Dichtungssitz (9) der Gleitringdichtungsanordnung (8) in einem ringförmigen Protektor (10) aus einem korrosionsfesten Material ausgebildet, der fest im Wellendurchgang (4) der Rückwand (3) angeordnet ist.
