Chemical and Fertilizer Injection
Pumps Unlimited assists clients with
irrigation design and recommendations based on individual
requirement. We supply and install venturi-type, patented
Mazzei® injectors for injecting fertilisers, chemicals,
ozone gas, air, or oxygen into pressurised water systems.
Mazzei® 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 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.
How
a Mazzei® Injector Works
When pressurised 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 injector inlet pressure.
