Chemigation and Fertigation

MAZZEI Venturi Injectors…Efficiency at a Low Cost

Chemigation and fertigation are the most common applications for Mazzei® venturi injectors in the agriculture market. Mazzei pioneered this simple-to-use and easy-to-install solution more than 40 years ago. The process of injecting chemicals (chemigation) or liquid fertilizers (fertigation) into a pressurized irrigation system is inexpensive and easy with high-efficiency Mazzei injectors which deliver precise mixing and uniform distribution of material into the water stream. Mazzei injectors are designed for vacuum transfer of irrigation chemicals, providing additional chemigation safety.

Mazzei injectors have no moving parts, and they typically require no supplemental pump system. Instead, they use the flow of water in the line to create a vacuum to transfer irrigation chemicals, which also improves handler safety.

Mazzei-patented designs are precisely engineered and manufactured. The result is optimal performance that you simply can’t achieve with imitation products.
