FEATURES:

Superior Design:

  • Triplex plunger design gives smoother liquid flow.
  • V-Packings are completely lubricated and cooled by the liquid being pumped.
  • Lubricated Lo-Pressure seals provide double protection against external leakage.
  • Oil bath crankcase assures optimum lubrication.
  • Close tolerance concentricity of the ceramic plunger maximizes seal life.

Quality Materials:

  • Precision design 304 stainless steel valves and seats are hardened and polished for ultimate seating and
  • extended valve life.
  • Forged brass manifold for strength and corrosion resistance.
  • Special concentric, high-density, polished, solid ceramic plungers provide a true wear surface and
  • extended seal life.
  • Specially formulated, CAT PUMP exclusive, V-Packings offer unmatched performance and seal life.
  • Die cast aluminum crankcase provides high strength, minimum weight and precision tolerance control.
  • Chrome-moly crankshaft gives unmatched strength and surface hardness.
  • Oversized crankshaft bearings with greater loading capacity means longer bearing life.

Easy Maintenance:

  • Wet-end easily serviced without entering crankcase.
  • Valve assemblies are accessible without disturbing piping.
  • Interchangeable inlet and discharge valve assemblies.
  • Preset seals require no packing adjustment.

Triplex Plunger Pump Applications:

  • Car Washes
  • Hydrostatic Pressure Testing
  • Desalination
  • Chemical Injection
  • Industrial Machine Part Cooling
