The 3CP1120
Triplex plunger design delivers smoother liquid flow.  Hi-Pressure Seals are completely lubricated and cooled by the liquid being pumped.  Inlet and discharge valve assemblies interchange for easier maintenance.  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.

Quality Materials

Precision design 304 stainless steel valves and seats are hardenedand polished for ultimate seating and extended valve life.  Forged brass 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 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.
