Abstract

Die Erfindung betrifft einen Spaltrohrmotor 1 für eine Kreiselpumpe, mit einem Spaltrohr, das den als Naßläufer ausgebildeten und mit der Motorwelle 4 drehfest verbundenen Rotor 10 von dem drehfest mit dem Motorgehäuse 2 verbundenen Stator 11 trennt, wobei das Spaltrohr durch eine flüssigkeitsundurchlässige Folie 16 gebildet ist, und dass Stützelemente 15 vorgesehen sind, die die Folie 16 halten und/oder tragen.

Figure 00000001
The invention relates to a canned motor 1 for a centrifugal pump, with a can, which separates the rotor 10 formed as Naßläufer and non-rotatably connected to the motor shaft 4 of the rotatably connected to the motor housing 2 stator 11, wherein the can is formed by a liquid-impermeable film 16 , And that support elements 15 are provided, which hold the film 16 and / or wear.
