⚙️ CAT Pumps 4SPX32G1I Plunger Pump
The CAT Pumps 4SPX32G1I is a high-speed Triplex Plunger Pump engineered specifically for direct-drive gas engine systems. As a true Positive Displacement Pump, it utilizes three synchronized solid ceramic plungers to deliver a smooth, consistent flow that maintains cleaning efficiency even when resistance changes. The pump head is machined from a high-strength Brass manifold with 304 Stainless Steel valve assemblies, offering superior durability and corrosion resistance compared to standard axial pumps found on residential machines.
Designed for simple integration, the 4SPX32G1I features a 1" hollow shaft that mounts directly to the face of 9HP to 13HP gas engines. It arrives fully assembled with an integral regulating unloader valve and a fixed chemical injector, providing a complete "bolt-on" solution for commercial pressure washing applications. With a verified flow rate of 3.2 GPM at 3,000 PSI, it delivers the professional stripping power required for surface cleaning, fleet washing, and industrial maintenance.
