Big John Manufacturing

Chemigation Unit


This self-contained unit can easily be moved pivot to pivot. The 1.5 hp model has wide range of pumping capacities from ounces to 50GPH. Its design only lets fresh water go through the injector pump and has a safety shut off valve for back flow which isolates chemical tank from irrigation system during shut down or in case of power failure or loss of line pressure. The capacity and low maintenance of the system offers the grower more flexibility than any other system on the market.
