Abstract
Die Erfindung betrifft eine Nassläufer-Motorpumpe mit einem Spaltrohr (5), das den Motorstator (4) von dem im Spaltrohr (5) auf einer Motorwelle (2) gelagerten Rotor trennt, wobei die Motorwelle (2) in die Pumpenkammer (10) hineinragt und dort das Pumpen-Laufrad (1) trägt, und wobei auf der Laufradrückseite ein koaxialer zur Pumpenkammer (10) offener Ringraum (12) besteht, wobei die Laufradrückwand im Bereich des Ringraums (12) eine gedrosselte Durchflussöffnung (15) aufweist, die den Ringraum (12) mit dem Laufradinneren insbesondere mit der Pumpensaugseite verbindet.
