CAT Pumps 66DX30G1I Plunger Pump
The CAT Pumps 66DX30G1I is a professional-grade Triplex Plunger Pump specifically engineered for high-pressure direct-drive applications. As a true Positive Displacement Pump, it features three synchronized solid ceramic plungers that deliver a precise, consistent flow rate, ensuring stable performance even under heavy load. The pump head is constructed from a high-strength Forged Brass manifold with 304 Stainless Steel valve assemblies, providing exceptional durability and resistance to thermal shock in demanding commercial environments.
Designed for easy "bolt-on" installation, the 66DX30G1I features a 1" hollow shaft that mounts directly to the face of 9HP to 13HP gas engines (such as the Honda GX270 or GX390). It arrives fully assembled with a modular regulating unloader valve and a fixed chemical injector, making it a complete replacement solution for industrial pressure washing systems. With a verified flow rate of 3.0 GPM at 4,000 PSI, it provides the high-impact blasting power needed for heavy-duty stripping, graffiti removal, and surface preparation.
