<p>An arrangement for delivering fluids has a fluid pump having a pump wheel (90), which wheel is joined to a first permanent magnet (92). The pump wheel (90) is rotatably arranged inside a liquid-tight pump housing (80, 82, 84, 86, 88). This housing is shaped, near the first permanent magnet (92), as a partitioning can (80, 82). The arrangement also has an electronically commutated electric motor (20) having a stator (22) and a rotor (26) arranged rotatably relative thereto, which rotor comprises a second permanent magnet (67) that coacts with the first permanent magnet (92) to act as a magnetic coupling (94). Arranged in the space between the second permanent magnet (67) and partitioning can (80, 82) is a plurality of soft ferromagnetic magnetic flux conductors (150).</p> |
