Features

• Triplex plunger design provides smoother liquid flow.
• V-Packings are completely lubricated and cooled by the liquid being pumped.
• Special ported inlet manifold permits an external flush liquid, providing cooling for high-temperature liquids and lubrication for low-lubricity liquids.
• Lubricated Lo-Pressure Seals provide double protection against external leakage.
• Oil bath crankcase assures optimum lubrication.
• Close tolerance concentricity of the ceramic plunger offers perfect alignment and maximizes seal life.

Quality Materials

• Precision design 304 and 316 stainless steel valves and seats are hardened and polished for ultimate seating and extended valve life.
• Brass, Stainless Steel, Duplex SS, or Nickel Aluminum Bronze manifolds 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 mean 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.

Safety Note

All High Pressure Systems require a primary pressure regulating device (e.g., regulator, unloader) and a secondary pressure relief device (e.g., pop-off valve, relief valve). Failure to install such relief devices could result in personal injury or damage to the pump or property.

Electrical

Electric Horsepower Requirements

A table detailing electric horsepower requirements based on pressure (psi/bar) and flow (l/m) for a 1725 RPM motor with a standard 10” pump pulley is provided in the official PDF. See the official PDF for exact tabulated values.

Formulas

• 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.
