Abstract

Kreiselpumpe mit einem auf einer Welle gehaltenen Laufrad, das einen zentralen Saugmund als Eintrittsöffnung aufweist, wobei das über den Saugmund eingetretene Medium das Laufrad über mindestens eine Austrittsöffnung verläßt, wobei das Laufrad von einem die Laufradkammer bildenden Pumpengehäuse umgeben ist und wobei ein bei stehendem Laufrad 6 auftretender Leckfluß vermittels eines innerhalb des Pumpengehäuses 8 angeordneten Ventiles insbesondere durch eine axiale Verschieblichkeit des Laufrades blockierbar ist.
