Remco 7 GPM ProFlo “Fatboy” Electric Diaphragm Demand Pump 5538-1I1-94A – 7.0 GPM, 100 PSI, 12V
Sometimes your work requires all the flow you can get, along with a pump you can depend on time after time. When you need to count on dependable performance, the REMCO ProFlo FATBOY 5538-1I1-94A is ready for the job. These 12-volt diaphragm pumps are designed for use by professionals in agriculture, turf care, industrial transfer, and spraying applications. They move up to 7.0 GPM of fluid while maintaining steady pressure and long-term reliability.
The FATBOY has an automatic demand switch that turns on as soon as there’s a drop in pressure. It also automatically shuts off once demand is relieved. This reduces power consumption and helps extend the life of the pump. The sealed motor design prevents moisture and dirt from getting in, and the low amp draw uses less power—especially when on a mobile or battery-powered system.
In addition, the pump self primes up to 14 feet vertically. This means you’re ready to go in an instant, and it can quickly and reliably move fluid when you need it. The FATBOY can also be run dry without damaging internal parts. This prevents downtime in the field that can cost you time and money. Add to this chemical resistant Viton® valves and a Santoprene® diaphragm that’s abrasion and ozone resistant, and you can put this pump to work on a wide variety of spraying solutions.
Every REMCO pump is factory tested and proudly made in America. You can expect great performance right out of the box. The pump is also easy to set up and operate, so it makes your work simpler without sacrificing strength and quality.
