摘要: A combination pitot pump and centrifugal separator for pumping contaminated fluids and for separating contaminants from the pumped fluid includes a rotatable hollow casing. Contaminated fluid is delivered to the interior of the casing and a pumped fluid discharge duct is provided coaxially from the casing. A stationary pitot tube is supported within the casing for collecting, by a ram effect, cleaned fluid from the interior of the casing at a selected location between the casing axis and its outer periphery, and for converting the velocity head of the collected fluid to pressure in the course of supplying the collected fluid to the discharge duct. A plurality of orifices are formed through the outer periphery of the casing for discharging from the casing contaminant matter in fluid introduced into the casing and separated centrifugally therefrom within the casing. Vane means extend into close proximity to the inner surface of the casing at the outer periphery thereof for agitating and, if necessary, dislodging centrifugally separated accumulations of contaminant matter on the casing inner surface and thereby promote movement of the contaminant matter through the orifices. The outer end portion of the vane means may be arranged to direct a jet of relatively clean fluid to the inner surface of the casing.
