US Patent 9284953 Multiple port discharge manifold fluid end

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.
