Overview Reviews Product Description FEATURES: 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 SPECIFICATIONS: Maximum Volume: 4.5 GPM Maximum Discharge Pressure: 4000 PSI Maximum Pump Speed: 1645 RPM Bore: 16mm (0.630") Maximum Inlet Pressure: 60 PSI Crankcase Capacity: 17 oz.
