A centrifugal pump is provided for generating a relatively high pressure fluid discharge. The pump includes a stationary, enclosed rotor housing having a fluid inlet and a fluid outlet. A rotor assembly is rotatably supported in the rotor housing. The rotor assembly includes a chamber having a radial passage formed in one end thereof for fluid communication between the fluid inlet and a peripheral portion of the chamber. A drive shaft is rotatably supported in the rotor assembly and has a discharge tube formed therein with one end in fluid communication with the fluid outlet. A pair of hollow, radially extending pickup arms are attached to the drive shaft. Each pickup arm has an inlet positioned proximate the peripheral portion of the chamber and an outlet in fluid communication with the other end of the discharge tube. A drive means rotates the rotor assembly and the drive shaft in opposite directions with respect to each other and the rotor housing whereby a relatively high fluid pressure is generated at the fluid outlet.
