Can this unit draw from a water tank?

Yes — it's built for tank feeding, with a 1" barbed inlet sized for optimal draw from a supply tank. Mount it on a trailer, deck, or truck bed next to your tank and it's ready to plumb in.

Can it be converted to hot water?

Yes — the 26-amp high-output charging system on the Honda GX690 supports an optional Hot Box, so you can add hot-water capability later without changing the engine or pump.

Why does gear drive matter on this machine?

The 2:1 gear drive lets the General TSF2021 pump turn at roughly half engine speed, and a low-RPM pump runs cooler and lasts longer than a direct-drive setup. That's why gear-drive skids are the standard choice for daily commercial use.

Is this unit available in California?

No — this unit is not for sale in the state of California. If you're a California buyer, contact us and we can point you to a compliant alternative.

Overview

The SS/SG8535HG is a skid-mounted 8.5 GPM, 3500 PSI unit built on a 304 stainless steel base, powered by an electric-start Honda GX690 V-Twin and a General Pump TSF2021 industrial pump. The 2:1 gear drive runs the pump at low RPM — the setup you want for long pump life on a machine that works every day. It's tank-feed ready with a 1" barbed inlet and a remote 6-gallon rust-free poly fuel tank, so it drops straight onto a trailer, deck, or truck bed. The 26-amp high-output charging system supports an optional Hot Box. Made and assembled in the USA; not for sale in California.
