Product Description

Each Mazzei Suction Line / Injector Kit includes a Suction Line Kit, the F-30 L Liquid Flow Meter and a Venturi Injector. All parts are sold separately if one of these kits does not meet your system needs.

Mazzei Venturi systems offer a low cost solution for precise chemical applications in agricultural irrigation systems. Injecting chemicals into a pressurized irrigation system known as (chemigation) is the most common application for Mazzei Injectors in agriculture. 

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. 

Mazzei pioneered this simple-to-use, 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 advantage of an easy to maintain, non-mechanical system. With no moving parts, and often, no supplemental pump system, Mazzei is a cost-effective choice. Because Mazzei Injectors are designed for vacuum (not pressure) transfer of irrigation chemicals, they provide safe chemigation.
