P10821WS.S03 CENTRIFUGAL SUCTION PUMP ABSTRACT OF THE INVENTION A centrifugal suction pump includes a vertically disposed support tube having upper and lower ends, a liquid check valve on the lower end of the support tube, and a hollow rotatable hub mounted on the upper end of the support tube. A number of horizontally expeller tubes are connected to the hub and extend radially therefrom. A check valve is associated with the hub for venting the hub to ambient atmosphere and a priming conduit is connected to the support tube for filing the latter and the expeller tubes with liquid. A stopper is associated with each expeller tube and has an operative position that seals the expeller tube. Rotation of the expeller tubes causes radial displacement of liquid therein which effects movement of the stoppers to an inoperative position at which the tubes are unsealed and liquid is pumped up the support tube.
