Mazzei Venturi Fertilizer Injectors

Mazzei Injectors are extremely efficient, compact differential injection devices. Currently operating successfully in thousands of installations worldwide, Mazzei Injectors offer a reliable, accurate, and economical method to inject virtually any liquid or gas substance into a pressurized fluid stream.

Mazzei® venturi injectors are differential pressure injectors with internal mixing vanes. The unique, patented design and precision construction of Mazzei injectors maximizes injector efficiency, suction capacity and mixing capabilities. Our injectors also have no moving parts, which simplifies maintenance, and they have much lower operating costs than less efficient systems.

HOW IT WORKS

When pressurized water enters the injector inlet, it is constricted toward the injection chamber and changes into a high-velocity jet stream. The increase in velocity through the injection chamber results in a decrease in absolute pressure, creating a vacuum that draws a liquid or gas additive through the suction port and mixes it thoroughly into the water stream. As the jet stream is diffused toward the injector outlet, its velocity is reduced and resumes its flow in a thoroughly mixed state with slightly lower energy than when it entered the injector.

FEATURES

• Molded from high quality thermoplastics with superior strength, high temperature capability and resistant to most chemicals
• No moving parts, low maintenance trouble-free operation
• Unique design allows maximum cavitation in the injection chamber, thereby providing instantaneous mixing
• Ideally suited for continuous mixing functions, requires no secondary blending devices
• Initial cost and installation cost are low
• Powered by the motive fl uid, no external energy required for most installations
• Available in a broad range of sizes, flows and injection capacities

APPLICATIONS

The highly versatile Mazzei Injectors are suitable for a wide variety of applications -

• Agriculture
• Ag Irrigation Systems - to inject fertilizers and other chemicals or water treatment additives.
• Ag Spray Systems - for mixing and/or the transfer of concentrated pesticide materials.
• Food Processing - for water chlorination, injection of detergents, bacterial agents and other water treatment purifi cation additives.
• Home and Garden
• Irrigation Systems - for application of liquid fertilizer through landscape sprinkler or drip irrigation systems, hose end sprinklers and/or spray nozzles. (Check local guides)
• Industrial/Commercial
• Water Treatment - to inject air, liquids, gases (ozone) and other water purifi cation chemicals for cooling tower or other water or fluid recirculatory systems, waste water systems and potable water systems.
• Washing and Cleaning - to inject detergents, solvents and other cleaning agents into carpet cleaning equipment, car wash systems, dishwashing equipment and other industrial cleaning processes
