  • Fluid End Assembly with Modified Suction Block
    Publication number: 20190264680
    Abstract: A suction block for use in a fluid end assembly of a high pressure reciprocal pump includes a first suction bore extending from a first face of the suction block and into the interior thereof; and a second suction bore extending from a second face of the suction block and into the interior thereof to intersect the first suction bore. The second suction bore is adapted to receive a valve assembly for alternatively fluidly connecting and disconnecting the first and second suction bores. The first suction bore has a first suction bore section with a first geometry and a second suction bore section with a second geometry different from the first geometry to thereby reduce stress in the suction block during use.
