Overview

This is a commercial belt-drive cold water pressure washer delivering 8.0 GPM at 3500 PSI, built around an electric-start Honda GX690 engine and a low-RPM General Pump. The 4-groove cog V-belt (3VX) drive lets the pump turn slower than a direct-drive unit, which means less heat, less vibration, and a longer pump life under daily commercial use. It's skid-mounted on a heavy-duty stainless steel base and comes tank-feed ready with a 1" barbed inlet and external bypass hose, so you can run it off a buffer tank on a flatbed or trailer. The high flow makes it a strong pick for fleet washing, flatwork with a surface cleaner, and heavy commercial cleaning where volume moves the job faster than pressure alone. Battery not included.

Frequently asked questions

Yes — it ships tank-feed ready with a 1" barbed inlet and an external pump bypass hose. That makes it well suited to buffer-tank setups on trailers and flatbeds, and the thermo-sensor protects the pump from overheating while it sits in bypass.

It includes a heavy-duty gun/wand assembly, 50' high-pressure hose with QC couplers, a Maxi-Flo 20% chemical injector, four color-coded stainless quick-connect spray nozzles, one brass chemical nozzle, a remote six-gallon poly fuel tank, and a marine battery box for the electric start.

A belt drive runs the pump at a lower RPM than the engine, which reduces heat and wear and significantly extends pump life. This unit uses a 4-groove cog 3VX V-belt for balanced power transfer, with an easy-access interlocking belt cover for service.
