Abstract
A plunger pump fluid end housing assembly comprising: a fluid end housing, multiple plungers, a single in-line suction valve and seat corresponding with each said plunger, a discharge valve and seat corresponding with each said plunger; wherein axis of said suction valve and seat are parallel with said plunger, and the suction manifold is positioned to feed the fluid chamber opposite the power end of the fluid end. Plunger chamber of said fluid end housing is square or rectangular in cross section with large fillets at corners and flats between said fillets. Said flats are approximately equal in width to radii of said fillets.
Claims20
A plunger pump fluid end housing with multiple fluid chambers arranged in longitudinal plane and each fluid chamber comprising:
- a suction bore;
- a plunger bore;
- a valve spring retainer/plunger spacer in said plunger bore;
- a discharge bore;
- wherein axes of said suction bore and plunger bore are parallel;
- wherein an axis of the discharge bore is substantially perpendicular to said suction bore and plunger axes;
- wherein the cross section of a plunger chamber is substantially rectangular and the corners of said substantially rectangular cross section are filleted;
- wherein each side of the rectangular plunger chamber, between said corners, is planar in shape;
- wherein said valve spring retainer/plunger spacer comprises:
- four tangs providing an inner surface having a circular cross section and an outer surface complimentary to said substantially rectangular cross section of said plunger chamber;
- and
- wherein a port connecting the discharge bore with plunger chamber intersects the said plunger chamber wholly within a planar section.
