Chemical and Fertilizer Injection
Mazzei® Fertilizer Injectors
Pumps Unlimited assists clients with irrigation design and recommendations based on individual requirements. We supply and install venturi-type, patented Mazzei® venturi injectors for injecting fertilizers, chemicals, ozone gas, air, or oxygen into pressurized water systems.
Mazzei® Venturi Injectors are high-efficiency differential pressure injectors with internal mixing vanes.
When sufficient pressure difference exists between the inlet and outlet ports of the injector, a vacuum is created inside the injector body, which initiates suction through the suction port.
Mazzei® Injectors are incredibly 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.
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 pressure, 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 pressure energy but at a pressure lower than the injector inlet pressure.
Special Features of the Mazzei® Venturi Injectors
- Single-unit construction – trouble-free operation with no moving parts
- The constant injection of material assures uniform distribution
- Proven performance with years of expected service life
- Safe to use as the chemicals are under vacuum, not pressure
- No electrical connections needed
- Can run dry with no problems
- Considerable cost savings versus other injection methods
- Molded Polypropylene or PVDF (KYNAR®) ISO-R (BSPT) threads are available
