MAZZEI® VENTURI INJECTORS

Mazzei Venturi Injectors are differential pressure injectors with internal mixing vanes. Superiority of Mazzei Injectors is due to the unique, patented design which maximizes injector efficiency, suction capacity and mixing capabilities. The operating costs of Mazzei Injectors are lower than less efficient systems, and Mazzei Injectors are trouble-free because they have no moving parts.

 

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, thereby enabling an additive material to be drawn through the suction port and entrained 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.

 

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 micro bubbles which greatly increases the surface area of gas (oxygen, ozone, etc.) in contact with the liquid (several micro bubbles have a greater surface area than one large bubble of the same volume).

 

Why Mazzei?

  • Proven performance with years of expected service

  • No electrical connections needed

  • Can run dry with no problems

  • Considerable cost savings versus other injection methods

  • Safe to use as the chemicals are injected under vacuum, not pressure

  • Injectors are available in stainless steel, Polypropylene (PP), Polyvinylidene Fluoride (PVDF), natural PVDF or Ethylene Chlorotrifluoroethylene (ECTFE).
