Mazzei PVDF Venturi Injector
Mazzei Injectors offer the advantage of an easy to maintain, non-mechanical system that is a cost-effective choice.
Mazzei Venturi Injectors are one of the easiest injector systems to install and use. Mazzei's proven patented design delivers chemicals with greater precision than many other types of injectors. The Mazzei Venturi Injectors are self priming and will not be hurt if they run dry. The PVDF (Polyvinylidene fluoride or polyvinylidene difluoride) model is made to hold up chlorine and sulfuric and nitric acids, plus are more resistant to ozone and UV damage. These are commonly used in pool or spa applications and in waterscapes.
Mazzei injectors use differential pressure between inlet and outlet to create a vacuum that draws the chemicals through the suction port into the injector. Mixing vanes then ensure even distribution of chemicals into the 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 http://injectorselector.mazzei.net/ .
- No moving parts to wear or break
- Self priming and easy to use
- Uniform chemical distribution
- Injection stops when water flow stops
- Highly resistant to most acids and alkalis
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.
