FEATURES

Superior Design

• Triplex plunger design provides smoother liquid flow.
• Hi-Pressure Seals are completely lubricated and cooled by the liquid being pumped.
• Special flushed Inlet Manifold permits external flush for added cooling with high temperature liquids and lubrication with low lubricity liquids.
• Lubricated Lo-Pressure Seal provides double protection against external leakage.
• Oil bath crankcase assures optimum lubrication.
• Close tolerance concentricity of the ceramic plunger maximizes seal life.
• Optional direct drive electric motor models.

• Precision design 316 stainless steel valves and seats are hardened and polished for ultimate seating and extended valve life.
• 316 Stainless Steel 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, 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.

• 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.
