Abstract
A fluid pump for delivering accurate volumes of high-pressure fluids is obtained using an intensifier to supply the majority of the motive power required to displace the fluids. The intensifier balances the forces between the output pressure of the displaced fluid (above a convention drive piston) with a large diameter booster piston that is driven pneumatically by low-pressure gas. A small horsepower motor provides needed power to overcome the friction of the high pressure gas pump, the differential pressure needed for the use of the pump, and to accurately control or trim the high-pressure output or rate to a precise value. A ball screw and spur gears are used to transmit the power. The pump is uniquely designed to reduce the stress from the motor to the components.
