Arrangement for conveying fluids

An arrangement for conveying fluids that comprises

• a fluid pump (174), implemented as a centrifugal pump, having a pump wheel (172) that is joined to a first permanent magnet (186)
• an electronically commutated internal-rotor motor (152) having a stator (154) and a permanent-magnet rotor (156);
• a shaft (160) associated with the rotor (156), which shaft is journaled on bearings (162, 164) rotatably, relative to the stator (154);
• a separating can (170, 180, 188) that surrounds in fluid-tight fashion the first permanent magnet (186) arranged inside that separating can, a first bearing (164) for the shaft of the rotor (156) being arranged on an outer side of the separating can thereon;
• a support arrangement (204) , joined to the stator (154) , for a second bearing (162) of the shaft (160) of the rotor (156);
• a fan wheel (218), equipped with fan blades (220), that is joined nonrotatably to an end region (214) , facing away from the separating can (170, 180, 188), of the shaft (160) of the rotor (156) ;
• and
• a second permanent magnet (184) implemented as an extension of the permanent-magnet rotor (156), which magnet overlaps the first bearing (164) , coacts with the first permanent magnet (186) in the manner of a magnetic coupling, and is hermetically separated from the first permanent magnet (186) by the separating can (170, 180, 188).
