Electrical

• Electric Horsepower Requirements: A detailed table is provided in the official PDF, outlining electric horsepower requirements for various flow rates and pressures at 1000, 1200, and 1500 RPM. See the official PDF for exact tabulated values.
• Formulas for System Sizing:
  • Determining the Pump R.P.M.: (Rated G.P.M. / Rated R.P.M.) = ("Desired" G.P.M. / "Desired" R.P.M.)
  • Determining the Required H.P.: (GPM x PSI) / 1460 = Electric Brake H.P. Required
  • Determining Motor Pulley Size: (Motor Pulley O.D. / Pump R.P.M.) = (Pump Pulley O.D. / Motor R.P.M.)

Features

• Superior Design:
  • Triplex plunger design gives smoother liquid flow.
  • V-Packings are completely lubricated and cooled by the liquid being pumped.
  • Inlet and discharge valve assemblies interchange for easier maintenance.
  • 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 and 316 stainless steel valves and seats are hardened and polished.
  • Forged Brass or Stainless Steel manifolds are strong and corrosion resistant.
  • 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 mean longer bearing life.
• Easy Maintenance:
  • Wet-end is easily serviced without entering crankcase.
  • Preset packings mean no packing gland adjustment is necessary.
