CAT Pumps 2SF35GS Plunger Pump
The CAT Pumps 2SF35GS is a premium Triplex Plunger Pump engineered specifically for direct-drive gas engine applications. As a true Positive Displacement Pump, it delivers a precise volume of water with every rotation, ensuring consistent flow stability even when facing backpressure. The pump head is constructed from a special high-strength Brass manifold and 304 Stainless Steel valve assemblies for superior durability and corrosion resistance, significantly outlasting standard aluminum consumer pumps.
Designed for ease of installation, the 2SF35GS features a 3/4" hollow shaft that bolts directly to standard 5.5HP–6.5HP gas engines. It comes fully integrated with a regulating unloader valve and a fixed chemical injector, making it a complete solution for portable pressure washing equipment. With a verified flow rate of 3.5 GPM at 2,000 PSI, it provides increased rinsing volume for faster cleaning on siding, vehicles, and flatwork.
