摘要： A plunger pump fluid end housing in which the access, suction, and discharge bores within each fluid chamber are offset from the plunger bores. The plunger bore centerline being fixed by the spacing in the pump power end section. The access, suction, and discharge bores in the outside fluid chambers of the pump are offset toward the center of the fluid end. The direction of the offset of the outside fluid chambers opposes the direction of offset of the opposite outside fluid chambers. A special access bore plug with asymmetrical integral spacers is also disclosed.

摘要： A fluid end assembly comprising: a housing, valves, seals, seats, springs, plungers, plunger packing, and other associated parts, paired with a suction manifold that facilitates fluid feeding through a centrally located external suction intake. The suction manifold of this invention is designed to preserve fluid energy that will ensure complete filling of the cylinder in extreme pumping conditions. The suction manifold utilizes a chamber design positioned immediately below the suction valves, eliminating all connecting ducts. The design of the manifold of this invention can be easily fabricated utilizing commercially available steel plate, pipe, and pipe fittings.

摘要： A plunger pump fluid end assembly design in which the suction valve and seat is aligned with the plunger and the fluid end housing is constructed with multiple modules. Modules are held in a rigid assembly by staybolts that connect to the power end of the plunger pump. Said staybolts pass though bores in the central fluid module and the suction seat module and bound by a conventional threaded nut. Packing box modules are bound to the central fluid module by bolts that also pass through separate bores in the same central module. A suction valve spring retainer/plunger spacer within the plunger bore of the assembly shields the intersection of the plunger bore and the discharge bore from destructive erosion damage.

摘要： A fluid end assembly comprising a fluid end housing with multiple discharge manifold ports which provide a fluid end assembly that overcomes problems associated with prior art single port discharge manifold designs that result in non-symmetrical flow of discharged fluids through the fluid end discharge valves, resulting in premature failure of said valves. The multiple port discharge manifolds overcome problems associated with non-symmetrical flow of discharged fluids through a fluid end discharge valve, thereby improving valve life and performance.

摘要： A positive displacement pump fluid end with multiple fluid chambers and each fluid chamber comprising a valve body, valve seal, seat, spring, and external guide. External top male stem guide is integral to the fluid end discharge cover or the suction valve spring retainer. Female guide is internal and integral with the valve body. When the valve opens hydrodynamic forces and moments align the valve to prevent rotation. An embodiment features tapered male and female guide members to further assist in correct alignment of the valve with the seat. Various additional embodiments assist in venting any trapped fluids between the male and female portions of the guide.
