This Everflo EF5500 12 volt 20.8 L/min 4 bar pump is the ideal choice for fluid transfer applications. It boasts a host of features such as a Honeywell Micro Switch, Viton valves, a Santoprene diaphragm, and a fiberglass-reinforced polypropylene manifold with 3/4 Quick Attach Ports. A unique pressure switch cycles the pump slowly to reduce wear on the motor and switch, while an automatic power switch turns off the pump when no flow is needed. With its standard mounting pattern for easy installation and a CE certification, it is suitable for use with Round-Up© and agricultural herbicides and insecticides. This diaphragm pump is designed for diverse water delivery applications, including agricultural spraying, mobile pressure washing, water transfer, irrigation, fire suppression, and mist spraying.
