  • Actuating device for a pump unit
    Patent number: 10294996
    Abstract: An actuation device for a pump assembly such as for application in a can of a pump assembly for force impingement of a shaft situated in the can. The device includes a carrier for connection to the can and a passage extending along a longitudinal axis. An actuation pin is led in the passage along a longitudinal axis and has a first axial end including a tool receiver and a an opposite second axial end including an engagement region for force transmission onto a shaft. A spring element is arranged between the actuation pin and the carrier and impinges the actuation pin with a spring force in a first axial end direction. A seal is arranged between the carrier and the actuation pin, in a region between the spring element and the second axial end. A pump assembly with such an actuation device is also provided.

  • Submersible motor for driving a centrifugal pump having a separating wall disposed in a rotor chamber-space
    Patent number: 5941695
    Abstract: A submersible motor for driving a centrifugal pump. The motor includes a rotor space filled with a fluid and the rotor space on the pump side is sealed by way of a sealing formation penetrated by the motor shaft which carries the rotor of the motor. In the rotor space between the sealing formation and the rotor there is provided a stationary separating wall, letting through the motor shaft, for forming a smoothing space in front of the sealing formation.
