Abstract: An in-line pump device having a hollow, power shaft formed with an internal rotary chamber having an impeller vane assembly mounted therein to pump a fluid therethrough, the power being supplied by a motor positioned substantially about the power shaft.

Abstract: A centrifugal pump has a rotor with two aligned frusto-conical passages, between the larger ends of which is a centrifugal impeller. The lower, smaller end of one of the passages forms a pump inlet. Frusto-conical funnels within the passages act to separate a vapor core from a liquid which is ejected by the impeller. The vapor is ejected from the smaller end of the other passage. A deflector and vanes within the rotor assist ejection of the vapor.

Abstract: A flow machine for pumping and/or measuring the flow of agressive, radioactive, or special-purity flow mediums. The flow machine is provided with a rotatable impeller magnetically supported within a machine casing such that the impeller is spaced at all points from the inside walls of the machine casing. The casing inside walls and the outer configuration of the impeller include a central cylindrical center section joined by conically outwardly flared end sections. Electromagnetics are arranged in the conical flared section outside of the inside wall for cooperation with magnetic material arranged in the corresponding conically flared sections of the impeller to support the impeller in position. The conically flared section facilitate both radial and axial support of the impeller, since both axial and radial components of electromagnetic force is experienced at the conically flared sections of the impeller.
