Claim 0:
1. A magnetic coupling pump apparatus, having a rotor shaft (16), having a pump impeller (22) which is securely connected to the rotor shaft (16), having at least one axial bearing (18) which rotatably supports the rotor shaft (16) at a side facing the pump impeller (22), having a magnetic pump stator (42), having a magnetic pump rotor (44) which is connected to the rotor shaft (16) in a rotationally secure manner, having a containment can (30) which extends between the magnetic pump stator (42) and the magnetic pump rotor (44) and which at least partially closes a central pump space (28), and having at least one central support element (32) which is mounted in a region of the pump impeller (22) in a rotationally secure manner, characterized by an elastomer disk (36) which is arranged between the support element (32) and the axial bearing (18) and characterized in that the magnetic pump stator (42) and the magnetic pump rotor (44) are arranged with an axial offset (X) with respect to each other, whereby, as a result of the axial offset (X), the magnetic pump stator (42) and the magnetic pump rotor (44) produce an axial force F(ax, mag) in a direction of the elastomer disk (36) and a thrust washer (38) is arranged between the elastomer disk (36) and the axial bearing (18).
