  • Dual integrated pump having a first and second pump portion connected in series and driven by a common shaft
    Patent number: 10544788
    Abstract: A pump includes a housing, a drive shaft, a centrifugal pump portion having an impeller, and a gear pump portion having first and second gears. The impeller and one of the first and second gears are mounted to the drive shaft to drive the centrifugal pump portion and the gear pump portion at the same rotational speed. The gear pump can be a crescent internal gear (CIG) pump. The drive shaft can be rotated by a magnetic drive. The drive shaft can include a longitudinal bore in fluid communication with a cavity in the magnetic drive and with a discharge of the centrifugal pump portion to circulate working fluid through the magnetic drive to cool the drive. An impeller can be coupled to an inlet of the centrifugal pump portion.
