Abstract
Plunger pump fluid ends incorporate housings with structural features that facilitate manufacture while providing improved internal access, reduced weight, and reduced likelihood of fatigue failures compared to conventional fluid end housings. Certain fluid ends incorporate frangible pressure relief means in suction valves for protection from overpressure-induced catastrophic failure. Oblong bore transition areas, when present, and barrel-profile central cavities provide obtuse bore intersection angles and effectively reduce fluid end weight while reducing peak cyclic fluid end housing stress by redistributing stress within the fluid end housing.
