CAT Pumps 3SPX30G1I Triplex Plunger Pump
The CAT Pumps 3SPX30G1I is a compact Triplex Plunger Pump engineered for high-performance cleaning applications. Designed as a direct-drive unit, it features a 1" Hollow Shaft intended to mount directly to the face of a gas engine (typically 9HP-13HP) operating at 3450 RPM. This pump is constructed with a high-strength forged Brass manifold and solid ceramic plungers, ensuring durability and resistance to corrosion in demanding environments.
This model comes equipped with an Integral Regulating Unloader and a fixed chemical injector, streamlining the installation process by combining pressure control and detergent application into a single unit. With a flow rate of 3.0 GPM and a pressure rating of 3,000 PSI, it provides the consistent power needed for residential and commercial pressure washing tasks. The "SPX" series design eliminates the need for belts or gearboxes, offering a simplified, maintenance-friendly solution for gas-powered systems.
