CAT PUMP MODEL 270 PUMP 3.5 GPM 1500 PSI 1420RPM 16.5mm SHAFT


Superior Design:

  • Triplex plunger design gives smoother fluid flow
  • High pressure seals are completely lubricated and cooled by the fluid being pumped
  • Inlet and discharge valve assemblies interchange for easier maintenance
  • Lubricated low pressure seal provides double protection against external leakage
  • Oil bath crankcase assures optimum lubrication
  • Close tolerance concentricity of the ceramic plunger maximizes seal life

Quality Materials:

  • All stainless steel valves are heat treated and seats are roller burnished for a positive seal and extended valve life
  • Brass, stainless steel, or nickel aluminum brass manifolds for strength and corrosion resistance
  • Special hardened, polished surface of solid ceramic plunger is abrasion resistant and results in extended seal life
  • Specially formulated CAT PUMP exclusive, HI-Pressure seals offer unmatched performance and seal life
  • Diecast 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 mean longer bearing life

Easy Maintenance:

  • Wet end is easily serviced without entering crankcase, requiring less time and effort
  • Valve assemblies are accessible without disturbing piping, for quick service
  • Preset packings mean no packing gland adjustment is necessary, reducing maintenance costs
