ABSTRACT:
An ultra high pressure fluid end for a reciprocating pump. The pump fluid end has a built-in accumulator characterized by an annular volume chamber defined in a body of the pump end. There may be a plurality of such chambers which are interconnected by a discharge manifold which is also in communication with an outlet of the body. The pump fluid end also uses frictional clamping to connect the pump plunger to the drive end of the pump. The frictional clamping includes a collet assembly comprising a split collet positioned around an end of the plunger, a collet hub disposed around the collet, and an adapter adjacent to the collet hub. Fasteners are used for clamping the collet hub to the adapter and thereby causing the collet to clampingly or grippingly engage the plunger. Coaxial inlet and outlet valves are provided in the body. A pressure retainer is disposed in the body around the plunger, and packing is used to seal between the plunger and the pressure retainer.
