The Professional Model Pump was designed for recreational fuel and fluid transfer uses as well as commercial applications. The fluid transfer pump was developed from a plastic composite material that is compatible with all fluid types ranging from water and fuels to even the harshest of chemicals. The Professional Model Pump, our patented technology, was designed for FLO-FAST containers, as well as all industry-standard, large mouth containers (jugs) with a 3 inch opening. Additionally, the pump can adapt to industry standard 15, 30, and 55 gallon barrels with a bung adaptor. The pump has three internal vanes that build pressure to pump and draw fluid up to 8 gallons per minute. The FLO-FAST pump is ultra-durable, made to last, and will transfer fluids fast, safe, and easy.
