Features
Superior Design
- Triplex plunger design gives smoother liquid
- 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
- Oil bath crankcase assures optimum
- Close tolerance concentricity of the ceramic plunger maximizes seal
Quality Materials
- All stainless steel valves are heat treated and seats are roller burnished for a positive seal and extended valve
- Forged Brass, 316 Stainless Steel or Nickel Aluminum Bronze manifolds for strength and corrosion
- Special concentric, high density, polished, graphite impregnated, solid ceramic plungers are abrasion resistant and result in extended seal
- Specially formulated, CAT PUMP exclusive, V-Packings offer unmatched performance and seal
- Die cast aluminum crankcase provides high strength, minimum weight and precision tolerance
- Chrome-moly crankshaft gives unmatched strength and surface hardness.
- Oversized crankshaft bearings with greater loading capacity means longer bearing
Easy Maintenance
- Wet-end is easily serviced without entering crankcase, requiring less time and
- Valve assemblies are accessible without disturbing piping, for quick service.
- Preset packings mean no packing gland adjustment is necessary, reducing maintenance
