A fluid end of a high-pressure pump having a bore, a discharge bore, a suction bore, a valve cover bore, and a cross-bore intersection formed in portions of the fluid end. The bore, discharge bore, valve cover bore, and suction bore each having an opening which opens into the cross-bore intersection with the suction and discharge bores substantially orthogonal to the bore. A groove is formed in a wall of the fluid end within in the cross-bore intersection. The groove traverses a curvilinear path around an open space. The groove has a first section and a second section, each section having a first end and a second end. The first and second sections are separated by a gap proximate the bore and valve cover bore. A spring retainer is received into the groove and secured therein for pump operation. |
