Product Description

Mazzei® Venturi Injectors

Mazzei pioneered this simple-to-use, easy to install, injection 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 advantage of an easy to maintain, 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 (not pressure) transfer of irrigation chemicals, they provide safe chemigation.

The venturi style injector works off pressure differential to draw the solution into the injector system. Selecting the proper size injector unit for your application is very important. Mazzei has an "Injector Selector" on their website to help you choose which model best matches your needs. Go to .

How a Mazzei® Venturi Injector Works
When pressurized water enters the injector inlet, it is constricted toward the injection chamber and changes into a high-velocity jet stream. This increased velocity through the injection chamber results in a lower absolute pressure. This creates a vacuum, which enables an additive material to be drawn through the suction port and incorporate into the water stream. As the jet stream is diffused toward the injector outlet, its velocity is reduced and it is reconverted into lower pressure energy.
