US Patent 10995738 Fluid end and center feed suction manifold

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.
