Key Features and Materials

• Design: Triplex plunger design provides smoother liquid flow.
• Manifolds: Available in Brass, cast Nickel Aluminum Bronze, 316 Stainless Steel, or Duplex SS for strength and corrosion resistance.
• Plungers: Special concentric, high-density, polished, solid ceramic plungers provide a true wear surface and extend seal life.
• Valves & Seats: Precision design 316 stainless steel valves and seats are hardened and polished for ultimate seating and extended valve life.
• Packings: Specially formulated, CAT PUMP exclusive, V-Packings offer unmatched performance and seal life; completely lubricated and cooled by the liquid being pumped.
• Crankcase: Die cast aluminum crankcase provides high strength, minimum weight, and precision tolerance control; features an oil bath for optimum lubrication.
• Crankshaft: Chrome-moly crankshaft gives unmatched strength and surface hardness, supported by oversized crankshaft bearings with greater loading capacity.
• Inlet Manifold: Special ported inlet manifold permits an external flush liquid, providing cooling for high-temperature liquids and lubrication for low-lubricity liquids (e.g., DI water).
• Maintenance: Wet-end is easily serviced without entering the crankcase; inlet and discharge valve assemblies interchange for easier maintenance and are accessible without disturbing piping; preset packings mean no packing gland adjustment is necessary.

Safety Information

All systems require both a primary pressure regulating device (e.g., regulator, unloader) and a secondary pressure safety relief device (e.g., pop-off valve, safety valve). Failure to install such relief devices could result in personal injury or damage to the pump or to system components.
