ABSTRACT:
A high pressure pump includes a housing having a pump chamber therein for receiving a pump piston, and a separate pressure housing having a liquid pressure chamber therein in fluid communication with a pump discharge flow line within an outlet housing. A force-transmitting piston is provided within the pressure housing and is movable along an axis substantially coincident with the central axis of the pump piston to place a desired load on each of a plurality of compression rods. The pump may be initially manufactured with the pressure housing, or a separate pressure housing may be added to an existing pump without modifying other pump components. According to the method of this invention, a control valve in a compression line is opened, the pump is activated, then the compression line is closed to maintain the compression rods under load.
