1/2" Mazzei Venturi Fertilizer Injector (1.2-5.8 GPM)

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.

Features:

• Requires no electrical connections
• Runs dry with no problems
• Highly resistant to most acids and alkalis
• Versatile and cost-effective
• Imitations don’t perform as well as a Mazzei

Material:

• Body: Polypropylene

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. 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.

Performance

Mazzei venturi injectors operate over a wide range of pressures and require only a minimal pressure differential between the inlet and outlet sides to initiate a vacuum at the suction port. The injectors’ internal mixing vanes create thousands of microbubbles, which greatly increases the surface area of gas (air, oxygen, ozone, etc.) in contact with the liquid. Several microbubbles have a greater surface area than one large bubble of the same volume. Higher surface area facilitates greater solubility.

Why Choose Mazzei Injectors?

• Offers proven performance with years of expected service
• Requires no electrical connections
• Runs dry with no problems
• Provides considerable cost savings over other injection methods
• Safe to use as the chemicals are injected under vacuum, not pressure
• Imitations don’t perform as well as a Mazzei
