Superior Design:
• 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 hardened
and 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.
