We are an Authorized Distributor for Cat Pumps
This Cat Pump is a highly durable, industrial-duty direct-drive triplex plunger pump engineered specifically for high-pressure fluid transfer. As verified by the manufacturer, this positive displacement pump is highly recommended as a core component for professional gas-engine driven pressure washing systems and mobile commercial cleaning applications. It features a robust forged brass manifold paired with 304 stainless steel stacked valve assemblies. This high-strength construction provides exceptional structural integrity and wear resistance, making it an optimal choice for rigorous, intermittent-duty surface cleaning in harsh environments.
Designed to maximize operational efficiency and minimize installation complexity, this heavy-duty pump operates at a consistent flow rate of 2.5 GPM with a maximum pressure capacity of 3000 PSI at 3450 RPM. It utilizes advanced solid ceramic plungers that provide a true, low-friction wear surface, significantly extending the life of the standard NBR (Buna-N) seals and O-rings. The pump features an ultra-compact, 3/4-inch hollow shaft configuration with a standard 3/16-inch keyway, designed to bolt directly to a standard SAE J609 horizontal gas engine flange, eliminating the need for external belts or pulleys. To ensure seamless compatibility and achieve its maximum rated output, this pump requires a minimum 6.5 HP horizontal-shaft gas engine. Equipped with an integral pressure regulating unloader, a built-in bypass, and a fixed chemical injector, this pump delivers the precise system control and continuous power required for high-demand pressure washing operations.
