Abstract
A reciprocating plunger pump fluid end having increased material thicknesses in typical high stress concentration areas includes locating valves in spherically segmented shaped suction and discharge bores adjacent to chamfered transition areas to provide for reduced stress concentrations, resistance to fatigue failure and erosion and ease of access for maintenance. Among other features the housing includes a valve retainer assembly integrally mounted inside the housing which includes a profile to reduce stresses in the bores and facilitate access for replacement of internal components.
