 FEATURES

Superior Design

  • Triplex plunger design gives smoother liquid flow.
  • Inlet and discharge valve assemblies interchange for easier maintenance.
  • Oil bath crankcase assures optimum lubrication.
  • Close tolerance concentricity of the ceramic plunger maximizes seal life.
  • Standard Models: Lo-Pressure Seals and V-Packings are completely lubricated and cooled by the liquid being pumped.
  • Flushed Models: Special ported inlet manifold permits liquid to cool or flush between V-Packings and Lo-Pressure Seals providing protection against high temperatures or contaminating pumped liquids.

Quality Materials

  • Precision design 316 stainless steel valves and seats are hardened and polished for ultimate seating and extended valve life.
  • 316 SSL block-style manifolds for strength and corrosion resistance.
  • Special concentric, high-density, polished, solid ceramic plungers are provide a true wear surface and extended seal life.
  • Specially formulated, CAT PUMP exclusive, Hi-Pressure Seals offer unmatched performance and seal life.
  • Die cast aluminum crankcase provides high strength, minimum weight and precision tolerance control.
  • Optional Cast Iron crankcase for hazardous environments.
  • Chrome-moly crankshaft gives unmatched strength and surface hardness.

Easy Maintenance

  • Wet-end is easily serviced without entering crankcase, requiring less time and effort.
  • Preset packings mean no packing gland adjustment is necessary, reducing maintenance costs.
