Abstract
An arrangement for conveying fluids has a fluid pump () having a rotatably journaled pump wheel () that is joined to a first permanent magnet () and an electronically commutated internal-rotor motor () having a stator () and a rotor (), as well as a shaft () associated with the latter, which shaft is journaled rotatably relative to the stator () . The arrangement also has a second permanent magnet () joined nonrotatably to the rotor () , which magnet coacts with the first permanent magnet () to serve as a magnetic coupling. A separating can () hermetically separates the first permanent magnet () arranged inside the separating can, from the second permanent magnet () arranged outside the separating can. A fan wheel () mounted on the motor shaft, provides cooling air.
