  • Patent number: 10724526
    Abstract: A multi-stage horizontal centrifugal pump for conveying a fluid has a rotor including a rotatably arranged shaft and a plurality of impellers for conveying the fluid and a stator. All the impellers are arranged in a rotatably fixed manner on the shaft. The stator includes a plurality of stage casings, which are arranged consecutively one after another with respect to an axial direction determined by a central axis. The stator encompasses the rotor, and each stage casing is designed and arranged centrically with respect to the central axis. A plurality of wear rings is disposed between the rotor and the stator, each of which is fixed with respect to the stator, and surrounds the rotor with a clearance. At least one of the wear rings is designed eccentrically.

  • Publication number: 20190063449
    Abstract: A shaft bearing device for a pump includes an antifriction bearing, which can be connected to an axially displaceable pump shaft. A spring is arranged at the antifriction bearing in such a way, that a spring force can be transmitted to an outer ring of the antifriction bearing by the spring in a mounting condition of the shaft bearing device. A lifting element attached to the pump shaft and a corresponding counter element are separated from each other by the spring force in a starting state and/or in a shutdown state of the pump.
