Abstract
An arrangement for conveying fluids has a fluid pump () implemented in the manner of a centrifugal pump, having a pump wheel () that is connected to a first permanent magnet (). The arrangement further has an electronically commutated internal-rotor motor () having a stator (), inside which stator is rotatably arranged a rotor () that is in turn connected to a second permanent magnet () that coacts with the first permanent magnet () in the manner of a magnetic coupling (). The arrangement also has a partitioning can () that separates the first permanent magnet () of the magnetic coupling (), which magnet is arranged inside said partitioning can (), in fluid-tight fashion from the second permanent magnet () arranged outside the partitioning can (), the stator () of the internal-rotor motor () being arranged substantially in the same drive plane as the magnetic coupling () and radially outside the latter.
