Abstract

Das selbstansaugende Pumpenaggregat umfasst eine elektromotorisch angetriebene Kreiselpumpe, deren Pumpenlaufrad ein Ejektor koaxial vorgeordnet ist. Der einerseits an einen Saugstutzen der Pumpe angeschlossene Ejektor umfasst andererseits einen Einströmkanal (12) für das Entnehmen von Treibwasser aus dem Pumpengehäuse. Um ein luftfreies Entnehmen von Treibwasser in dem Pumpengehäuse sicherzustellen, ist dem Einströmkanal (12) des Ejektors eine Einströmverlängerung (18) vorgeordnet, deren Strömungseinlass (19) sich in Nähe des unteren Wandbereichs (6a) des Pumpengehäuses (6) befindet (Fig. 1).
