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 hi-temp 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 offers 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. The most popular direct-drive plunger pumps for self-service bays.
