Simpson 4000 PSI 4 GPM Gas Powered Hot Water Pressure Washer with 389 CC Honda Engine

The Simpson BB4040232E is a professional-grade hot water pressure washer engineered for power, reliability, and durability. Delivering 4,000 PSI at 4.0 GPM, it’s powered by a Honda GX390 engine with both recoil and key-start capability, paired with a Comet ZWD4040G industrial triplex pump for dependable, high-performance operation. Its 16" horizontal heating coil and 12VDC Wayne diesel burner provide a consistent 120 degrees fahrenheit heat rise, ideal for tackling grease, grime, and heavy industrial residue. The machine features a robust “Big Brute” rollover frame constructed from welded, powder-coated 1.5" steel tubing, mounted on 10" pneumatic tires for mobility and stability. Professional accessories include a 50-foot Armor high-pressure hose, 12 GPM hot-water spray gun, 48" insulated lance, four quick-connect nozzles (15 degrees, 25 degrees, 40 degrees, soap), and downstream detergent injection for flexible cleaning appliCations. Built for tough commercial environments, the BB4040232E combines Honda reliability with Simpson’s industrial design.
