Remco 7 Gpm Proflo “Fatboy” Electric Diaphragm Demand Pump 5538-1I1-94A

REMCO ProFlo “FATBOY” Electric Diaphragm Demand Pump – 7.0 GPM, 100 PSI, 12V

When your job calls for maximum flow and dependable performance, the REMCO ProFlo FATBOY 5538-1I1-94A delivers every time. Built for professionals in agriculture, turf care, industrial transfer, and spraying, this 12V diaphragm pump provides up to 7.0 GPM while maintaining consistent pressure and long-term reliability.

Unlike standard pumps, the FATBOY features an automatic demand switch that activates instantly when pressure drops and shuts off once demand ends. This design helps reduce power use and extends the life of the pump. Moreover, the sealed motor design keeps out moisture and debris, while the low amp draw ensures efficient power consumption—especially in mobile or battery-powered systems.

Additionally, this unit self-primes up to 14 vertical feet, so it’s always ready to move fluid quickly and reliably. You can also run it dry without damaging the internal components, which helps avoid costly downtime during field use. Combined with chemical-resistant Viton® valves and a durable Santoprene® diaphragm, the FATBOY easily handles a wide range of spraying solutions.

Because every REMCO pump is factory-tested and American-made, you can trust its performance right out of the box. From setup to operation, this pump simplifies your workflow without compromising strength or quality.
