Irrigation Chemigation


Injecting chemicals into a pressurized irrigation system (chemigation) is the most common application for Mazzei injectors in the agriculture market. Mazzei pioneered this simple-to-use and easy to install solution more than 40 years ago. Only Mazzei makes the process of injecting chemicals or liquid fertilizers (fertigation) into an irrigation system inexpensive and easy to use. High-efficiency Mazzei venturi injectors deliver precise mixing and uniform distribution of material into the water stream. Mazzei injectors have no moving parts, and typically require no supplemental pump system. They rely instead on a vacuum to transfer irrigation chemicals, which provides additional safety. Mazzei patented designs are precisely engineered—imitation products simply do not perform like a Mazzei injector.
