Electrical

Electric Horsepower Requirements

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 pump or property.

Features

• Superior Design:
  • Triplex plunger design for smoother liquid flow.
  • Special epoxy painted crankcase, bearing covers, and rear cover with liquid gasket seal provides added moisture protection (2530E Only).
  • Hi-Pressure Seals 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 316SS valves and seats are hardened and polished for ultimate seating and extended valve life.
  • Brass, 316 Stainless Steel, or Nickel Aluminum Bronze 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, Hi-Pressure seals 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.
  • Interchangeable inlet and discharge valve assemblies.
  • Preset seals require no packing adjustment.
