Features/Benefits

  • 40% stress reduction in bore intersection through improved geometry
  • Exhibits peak stresses within 5% of a Y-block fluid end, realizing a low stress advantage without higher maintenance requirements
  • Two-piece valve retainer allows easier assembly and gives line-of-sight confirmation for proper alignment not present with other grooveless fluid ends
  • 26% increase in flow area around suction and discharge valves, reducing cavitation and fluid-end wash outs
  • New geometry optimized to enhance the autofrettage process (validated using strain gauges)
  • Discharge flange allows full access for impact and torque wrenches, allowing accurate meeting of recommended torque specifications
  • Wing-style gauge connection retainer ensures safer installation by eliminating cheater bar
