A centrifugal fluid pump comprising a driven rotary assembly having at least two pumping stages operatively associated therewith and rotatable therewith as said rotary assembly is driven, each stage including a plurality of circumferentially spaced hydraulic cylinders operatively interconnected between a fluid supply tank that furnishes the respective hydraulic cylinders with the fluid and a pressure tank adapted to receive fluid under pressure from the respective hydraulic cylinders as the rotary assembly is driven. In operation, fluid is drawn into the hydraulic cylinders, and as the rotary assembly is driven the respective pistons of the hydraulic cylinders are driven radially outward causing fluid disposed on the outer sides thereof to be forced outwardly from the hydraulic cylinders under the influence of the centrifugal force generated by the rotary assembly. The pressure of the output fluid system is compounded by connecting the individual cylinders in series wherein the output of one cylinder is the input of an adjacently series connected cylinder. During this process, fluid is pumped from a supply tank through respective hydraulic cylinders of the pumping system, into a fluid pressure tank, the pressure of the fluid in the pressure tank being substantially greater than the pressure of the fluid in the supply tank as a result of the centrifugal force applied against the fluid as the rotary assembly is driven. It follows that the energy associated with the pressurized fluid can be harnessed by any suitable means, such as by pumping the pressurized fluid through a conventional hydraulic motor or using the pressurized fluid to drive some other fluid operated power generating mechanism.
