Pool Chemical Injection


Mazzei® venturi injectors deliver chemicals more safely and with greater precision and reliability than traditional delivery methods. If the water flow stops, injection stops instantly. The Mazzei injection system is simple to use and self-priming, Mazzei injectors are able to run dry with no problems, and, because they are made with special thermoplastics, they last longer.

The Mazzei injectors use differential pressure between inlet and outlet ports to create a vacuum, which draws chemicals through the suction port. Internal mixing vanes help ensure even distribution, and most installations do not require a pump or motor. Mazzei venturi injectors are available in PVDF—an advanced thermoplastic that is superior to other types of plastic including PVC, Polypropylene and Polyethylene. PVDF is resistant to chlorine, sulfuric and nitric acids, ozone and sunlight (UV). Let Mazzei be the solution for the chemical feed needs for your swimming pool, spa or waterscape.
