A pump having a canned motor which has a stator with an internal rotor disposed therein, the stator and the internal rotor being mutually separated fluid-tightly by a can disposed between stator and internal rotor, the stator having stator teeth which extend radially in the direction of the internal rotor and define with appurtenant stator-tooth end faces a receiving space for the internal rotor and the can, the can lying against the stator-tooth end faces, the can having on its surface facing the stator, in stator-tooth gaps which are respectively defined by two mutually adjacent stator teeth, ribs fitted in in a form-locking manner which taper in the radial direction, starting out from a rib root disposed on the can, with regard to a rib thickness defined in the circumferential direction of the can. |
