Patent ID: 8241016

Claim:
An arrangement, for conveying fluids, comprising: a fluid pump ( 91 ) implemented as a centrifugal pump, having a pump wheel ( 90 ) and a first permanent magnet ( 92 ) connected to said pump wheel ( 90 ); an electronically commutated internal-rotor motor ( 70 ) having a stator ( 68 ), inside which stator is rotatably arranged a rotor ( 60 ) that is connected to a second permanent magnet ( 76 ; 140 ) that coacts with the first permanent magnet ( 92 ) to serve as a magnetic coupling ( 93 ); a partitioning can ( 52 ) that hermetically separates the first permanent magnet ( 92 ) of the magnetic coupling ( 93 ), which magnet is arranged inside said partitioning can ( 52 ), from the second permanent magnet ( 76 ; 140 ), arranged outside the partitioning can ( 52 ), the stator ( 68 ) of the internal-rotor motor ( 70 ) being arranged substantially radially surrounding said magnetic coupling ( 93 ).
