Abstract (en)
The pump has an impeller e.g. single channel impeller, arranged in a pump housing (2). A seal is arranged at an end of the impeller and seals the impeller relative to a stationary part of the housing. The end of the impeller is axially placed at a distance from a suction port. The seal includes an impeller sided sealing ring (24) engaging in a pump housing sided sealing ring (26). The pump housing sided sealing ring includes a hole (28) for discharging solid particles from the impeller. The impeller sided sealing ring includes an actuator at an outer side for transporting the solid particles.

Eine Tauchpumpe weist ein in einem Pumpengehäuse (2) angeoranetes Laufrad (8) auf. Eine Dichtung (22) dichtet das Laufrad (8) gegenüber einem feststehenden Teil des Pumpengehäuses (2) ab. Diese Dichtung (22) weist einen laufradseitig angeordneten Dichtring (24) auf, der in einen pumpengehäuseseitig angeordneten zweiten Dichtring (26) eingreift. Zur Abfuhr von Feststoffteilchen aus dem Laufrad (8) weist der pumpengehäuseseitige Dichtring (26) mindestens eine Ausnehmung (28) auf. ( Fig. 2 )
