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.
