TURBINE PUMP Abstract of the Disclosure An improved pump for fluid is characterized by one or more turbine pumping stages each having outlet ports configured to provide a constant fluid pressure from the pump for various flow rates of the fluid. The stages are connectable in series so that each increases the pressure of the pumped fluid by a pre- determined amount, and each includes a housing having a pumping chamber with an inlet thereto and outlet ports therefrom, and an impeller rotatable in the chamber to move ends of blades thereof past the ports. The ports are uniquely configured to have fluid flow areas which increase with increasing distance from the chamber, whereby the pressure of the pumped fluid remains substantially constant for all flow rates of the fluid up to a design flow rate, and a fluid bypass port of adjustable flow area is provided in at least one of the pumping stages for controlling the pressure of the fluid at an outlet from the pump.
