Cat Pumps 2SFX22ES High Pressure Triplex Plunger Pump

Cat Pumps 2SFX22ES is a direct-drive, triplex (three-plunger) high‑pressure plunger pump designed for industrial cleaning and pressure‑washing applications. It delivers up to 2.2 GPM (8.3 L/min) at a maximum of 2,000 PSI, spins at 3,450 RPM, and uses a hollow 5/8‑inch shaft to bolt directly to a compatible electric motor for straightforward installation. The pump’s construction includes brass manifolds, 304 stainless steel valve assemblies, solid ceramic plungers, and Buna‑N (NBR) seals and O‑rings for durability. Inlet and discharge ports are 3/8" NPT (inlet 3/8" NPT F, discharge 3/8" NPT M), enabling easy plumbing to standard pressure‑washer components. A regulating unloader with bypass hose is standard on 2SFX pumps to provide pressure control and pump protection during operation. With its robust direct‑drive design and compact footprint, the 2SFX22ES is well suited for pressure washers and other high‑pressure cleaning systems that require reliable, long‑lasting performance.
