Remco Fatboy – High-Flow 12V Pump for Soft Wash Rigs

The Remco Fatboy 7.0 GPM 12V Demand Pump (SKU: 5518-1I1-94A) is a beast of a 12V diaphragm pump built for serious soft wash and pressure washing pros. It delivers up to 7.0 GPM at 100 PSI with automatic demand shut-off, meaning it runs only when you need it — saving battery life and reducing wear. Comes with 3/4" quick-attach ports (easy hose swaps) plus 1/2" barbs and lead wires for simple wiring. Shop Just Wash Stuff for pumps that actually move volume.

Built Tough for Chemicals & Daily Use

This pump features a Santoprene diaphragm, Viton valves, and corrosion-resistant internals — safe for sodium hypochlorite, detergents, and most soft wash mixes. The demand switch automatically turns it on/off with flow, and it’s self-priming with run-dry capability (won’t burn out if it runs dry briefly). Perfect for trailer-mounted soft wash rigs, backpack sprayers, or mobile pressure setups. Just Wash Stuff carries Remco’s top performers for reliability.

Why Pros Choose the Remco Fatboy 7.0 GPM Pump

You get serious flow (7 GPM) at low pressure (100 PSI ideal for soft wash), quiet operation, low amp draw for battery power, and quick-attach ports that make hose changes fast on the job. It’s a favorite for contractors who want high volume without the noise or maintenance of a gas engine. Shop Just Wash Stuff for 12V pumps that keep you moving.
