Cat 57 Plunger Pump 4.5 Gpm 4000 Psi

Genuine OEM Cat Pumps

This is a triplex [three plunger rods] positive displacement, reciprocating, plunger pump, constructed of a unchromed forged brass manifold, 304SS valve assemblies, solid ceramic plungers and standard NBR [Buna-N] seals and o-rings.

Features:

Superior Design:

• Triplex plunger design gives smoother fluid flow
• High pressure seals are completely lubricated and cooled by the fluid being pumped
• Inlet and discharge valve assemblies interchange for easier maintenance
• Lubricated low 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:

• All stainless steel valves are heat treated and seats are roller burnished for a positive seal and extended valve life
• Brass, stainless steel, or nickel aluminum brass manifolds for strength and corrosion resistance
• Special hardened, polished surface of solid ceramic plunger is abrasion resistant and results in extended seal life
• Specially formulated CAT PUMP exclusive, HI-Pressure seals offer unmatched performance and seal life
• Diecast 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
