  • Patent number: 4526517
    Abstract: In a centrifugal pump, a pumping section comprising a circular conduit has an input section subtending an arc on the circle. A plurality of channels connect the input section to an input conduit subtending an arc of a circle smaller than and concentric with or parallel to and vertically displaced from the circle defined by the pumping section. An output section subtends an arc defined by a circle concentric with and larger than the pumping section or vertically displaced therefrom. An impeller comprising vanes mounted on an annular disk is mounted in the pumping section and has magnetically saturable sections angularly spaced thereon driven by coils surrounding the pumping section and angularly spaced therealong.

  • Patent number: 4381181
    Abstract: A pump for moving conductive or non-conductive liquids having a closed loop duct with an inlet and an outlet. An impeller is located within the duct and includes a plurality of serially connected iron cores arranged for rotation within the duct. Movement of the cores within the duct is effected by a plurality of solenoids arranged externally and concentrically of the duct. Control means in the form of sensors actuate and de-actuate one or more of the solenoids. A method for pumping discrete and separated portions of fluid along a path of confinement is also set forth herein.
