• Superior Design
  
  
• Triplex plunger design gives smoother liquid flow.
• Hi-Pressure Seals or 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.
• Optional 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 for strength and corrosion resistance.
• Special concentric, high density, polished, graphite impregnated, solid ceramic plungers are abrasion resistant and result in extended seal life.
• Specially formulated, CAT PUMP exclusive, Hi-Pressure Seals or VPackings 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.
  
  
• 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.
