• Superior Design!
  
  
• Triplex plunger design gives smoother liquid flow.
• V-Packings are completely lubricated and cooled by the liquid being pumped.
• Inlet and discharge valve assemblies interchange for easier maintenance.
• 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.
• Convenient Gearbox Pump version for direct mounting to gas engine.
  
  
• Quality Materials!
  
  
• All stainless steel valves are heat treated and seats are roller burnished for a positive seal and extended valve life.
• Forged brass manifold is strong and corrosion resistant.
• Special concentric, high density, polished, graphite impregnated, solid ceramic plungers are abrasion resistant and result in extended seal life.
• Specially formulated, CAT PUMP exclusive, V-Packings offers unmatched performance and seal life.
• Optional FPM [Viton®] elastomers for liquid compatibility.
• 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, 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.
