Mazzei Injectors (patented) 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.


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, other water treatment purification 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 codes for backflow device requirements)

  • Industrial/Commercial
    Water Treatment - to inject air, liquids, gases (ozone), and other water purification chemicals for cooling tower or other water or fluid recirculatory systems, waste water systems, potable water systems.
    Washing & Cleaning - to inject detergents, solvents, and other cleaning agents into carpet cleaning equipment, car wash systems, dishwashing equipment and other industrial cleaning processes.


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


  • How Mazzei Injector Works
    When a pressurized operating (motive) fluid 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 pressure, thereby enabling an additive material to be drawn through the suction port and entrained into the motive stream. As the jet stream is diffused toward the injector outlet, its velocity is reduced and it is converted into pressure energy (but at a pressure lower then the injector inlet pressure.

  • Mazzei Injectors are extremely efficient, They 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.


Mazzei Typical Installation A
EXAMPLE A- Injector installed around a point of restriction such as a regulator valve or gate valve which creates a pressure loss, thereby allowing the injector to produce a vacuum.

Mazzei Typical Installation B
EXAMPLE B - Injector installed across the differential pressure created by an existing booster or supply pump in the system. It is plumbed from the discharge side to the intake side of the pump.

Mazzei Typical Installation C
EXAMPLE C - Injector installed in main flow line with flow control valve on bypass line.

Mazzei Typical Installation D
EXAMPLE D - Installed in conjunction with a centrifugal pump to boost pressure through the injector thereby creating a differential pressure and producing a vacuum for chemical induction downstream from the pump.
