Abstract: A device having a first and a second component, wherein the second component includes an opening, wherein the first component is mounted such that the first component can rotate in the radial direction and on one side in the axial direction in the opening of the second component about an axis of the first component, wherein the device is formed in such a manner that a fluid can flow in the axial direction through the opening of the second component, wherein the device also comprises at least two bearing shells, and rolling bodies, wherein a first of the bearing shells is fastened to or axially supported on the first component and a second of the bearing shells is fastened to or axially supported on the second component, wherein the rolling bodies are situated in the space circumscribed by the running faces of the two bearing shells, as a result of which a rolling bearing that can be loaded in the axial direction on one side is formed for axially bearing the first component in the second component, and wherein

Abstract: A wet rotor pump with an axial flux motor that includes a stator and a rotor. The stator is arranged in a dry zone while the rotor on an impeller is arranged in a wet zone. The rotor is formed by one or more samarium cobalt (SmCo) permanent magnets.

Abstract: A wet rotor pump with an axial flux motor that includes a stator, a containment shell, and a rotor. The stator and the containment shell are arranged in a dry zone while the rotor on an impeller is arranged in a wet zone. The wet rotor pump further has an inlet line for a fluid to be pumped by the impeller, said inlet line extending through the stator and the containment shell in an axial direction, and power electronics for controlling the stator, said power electronics being arranged within the space delimited by the stator and the containment shell.

Abstract: A wet rotor pump with an axial flux motor that includes a stator and a rotor. The stator is arranged in a dry zone while the rotor on an impeller is arranged in a wet zone. The wet rotor pump further has an inlet line for a fluid to be pumped by the impeller, and a bearing for the impeller. Said bearing is arranged at one end of the inlet line and supports the impeller in such a way that the impeller has an axial degree of freedom. The inlet line extends through the stator and the bearing in the axial direction. The bearing is a plain bearing which is used to radially support the impeller and axially support the impeller in one direction as an abutment for the magnetic force of attraction that the stator exerts on the impeller.

Abstract: The invention relates to a pump (1) for conveying of a fluid from an intake region (2) to an outlet region (3) which has a housing (4) and at least one rotor (6) which is arranged rotatable around an axis of rotation (5) and which can be driven by a driving element. To obtain a high degree of efficiency the pump according to the invention is characterized in that the rotor (6) has a bore (7), that a piston element (8) is arranged in the bore which can move along the longitudinal axis (L) of the bore and that a plurality of magnets (9, 9?, 9?, . . . ) or a ring magnet is arranged stationary in the housing (4), wherein the magnets or the ring magnet exert a magnetic attractive force on the piston element (8), wherein the magnets (9, 9?, 9?, . . . ) or a ring magnet are arranged in such a manner in the housing (4) that the piston element (8) carries out an oscillating movement (O) in the bore (7) during rotation of the rotor (6) around the axis (5) due to the magnetic attractive force.
