  • Patent number: 11927192
    Abstract: A pump apparatus has a rotor shaft, a pump impeller connected to the rotor shaft, at least one axial bearing which rotatably supports the rotor shaft at a side facing the pump impeller, a magnetic pump stator, a magnetic pump rotor which is connected to the rotor shaft, a containment can which extends between the stator and the rotor, and at least one central support element which is mounted in the region of the pump impeller. The pump apparatus has an elastomer disk which is arranged between the support element and the axial bearing. The stator and the rotor are arranged with an axial offset with respect to each other. The stator and the rotor are provided as a result of the axial offset to produce an axial force F in the direction of the elastomer disk.
