Mazzei 1-Inch Injector

$101.75 $102.60

Mazzei Injector Company, LLC is the world’s leading manufacturer of high-performance Venturi differential pressure injectors with internal mixing vanes that transfer or mix liquid or gas additives into solution. When a sufficient pressure difference exists between the inlet and outlet sides of the injector, a vacuum is created inside the injector body, which initiates suction of a liquid or gas through the suction port. Mazzei Injectors operate over a wide range of pressures and require only a minimal pressure differential between the inlet and outlet sides to initiate a vacuum at the suction port.


Precise chemical applications for irrigation systems...the low-cost solution.

Injecting chemicals into a pressurized irrigation system (chemigation) is the most common application for Mazzei Injectors in agriculture. Mazzei pioneered this simple-to-use and easy to install solution more than 30 years ago. Using high-efficiency patented and trademarked Mazzei Venturi injectors, Mazzei’s chemigation technology delivers a uniform distribution of chemicals and fertilizers within the irrigation water. Mazzei Injectors offer the advantages of an easy to maintain a non-mechanical system. With no moving parts, and often no supplemental pump system, Mazzei is the cost-effective choice. Because Mazzei Injectors are designed for vacuum transfer of irrigation chemicals, they provide safe chemigation.
