Abstract

Die Erfindung betrifft eine Pumpe, insbesondere Kreiselpumpe (1), die ein Pumpengehäuse (2) mit einem Einlass (3) und einem Auslass (4) aufweist, wobei eine Motorwelle (11), die mit einem im Pumpengehäuse (2) angeordneten Laufrad (12) drehfest verbunden ist, in einer Rückwand (5) des Pumpengehäuses (2) mit einer primären Gleitringdichtungsanordnung (14) drehbar gelagert ist, wobei der primären Gleitringdichtungsanordnung (14) ein Trockenlaufschutzsystem zugeordnet ist.
Um Stillstandszeiten der Pumpe zu Vermeiden und einen Wartungsaufwand gering zu halten, weist das Trockenlaufschutzsystem ein Flüssigkeitsvolumen (17) auf, das mit einer vom Laufrad (12) abgewandten Seite der primären Gleitringdichtungsanordnung (14) in Verbindung steht
