Abstract

Die Erfindung betrifft einen Spaltrohrmotor 1 für eine Spaltrohrpumpe, mit einem Motorgehäuse 4 und mit einem Spaltrohr 5, das den Naßraum 6, der den in der geförderten Flüssigkeit umlaufenden Rotor 8 aufnimmt, von dem trockenen Statorraum 7 abtrennt, wobei der Naßraum 6 an der von der Pumpe abgewandten Öffnung durch einen Deckel 11 flüssigkeitsdicht verschlossen ist, wobei der Deckel 11 einstückig mit dem Motorgehäuse 4 ausgebildet ist, und wobei ein Abdeckelement 14 vorgesehen ist, das zumindest die an den Naßraum 6 des Spaltrohrmotors 1 angrenzenden Bereiche des Deckels 11 flüssigkeitsdicht abdeckt.
