CAT Pumps 4SPX32G1I 4SPX-Series Plunger Pump

The CAT Pumps 4SPX32G1I is a highly durable, industrial-duty direct-drive triplex plunger pump belonging to the 4SPX Series. Engineered specifically for high-pressure washing applications and liquid transfer, this positive displacement pump is constructed with a high-strength brass manifold and 304 stainless steel valve assemblies. This robust construction ensures superior structural integrity and dependable continuous-duty performance, making it a premier choice for commercial cleaning equipment and gasoline engine-driven pressure washing systems.

Designed to deliver consistent power and operational efficiency, the 4SPX32G1I operates at a flow rate of 3.2 GPM with a maximum pressure capacity of 3000 PSI. It is equipped with advanced solid ceramic plungers that provide a true wear surface, extending the life of the standard NBR (Buna-N) seals and O-rings. Utilizing a 1-inch hollow-shafted configuration, this pump is designed to bolt directly to a standard gas engine flange, offering a compact and streamlined installation by eliminating the need for external belts or pulleys. An integral regulating unloader with a built-in bypass and a fixed chemical injector come standard, delivering precise system pressure control and versatile cleaning capabilities.
