Description

The Cat Pumps Model 56 is a heavy-duty, 5-frame triplex plunger pump designed for high-pressure industrial applications. It is widely considered a “step up” from the standard 310 or 340 models, offering higher flow and significantly higher pressure ratings.

Technical Specifications

• Flow Rate: 5.5 GPM (21 LPM)

• Pressure Range: 100 to 3500 PSI (7 to 241 bar)

• Speed: 1210 RPM

• Shaft Diameter: 24 mm (Solid Shaft)

• Inlet Port: 1/2″ NPT(F)

• Discharge Port: 3/8″ NPT(F)

• Max Liquid Temp: 160°F (71°C)

Key Features

• Industrial Construction: Features a forged brass manifold and 304 stainless steel valve assemblies for maximum corrosion resistance and strength.

• Solid Ceramic Plungers: Uses precision-ground alumina ceramic plungers (#43232) that provide a smooth, wear-resistant surface for the seals.

• Continuous Duty: The 1210 RPM speed allows for long-running cycles in industrial wash-down, hydrostatic testing, and high-pressure injection.

• Versatility: Can be belt-driven or coupled to a motor, providing flexibility for different power sources.
