Venturi Injector

Venturi injectors are a highly efficient way to introduce liquid or gas into water. They are ideal for dosing chemicals, aerating water, dosing ozone and fertilizer application through drip irrigation.

How does a venturi work?

Venturis work on a principle of differential pressure.
Water flows into the venturi at a higher pressure than that at which it exits. This pressure difference creates a vacuum at the suction port on the side of the device. This sucks air, ozone, or liquid into the main water stream. So, the greater the difference in pressure, the greater the vacuum and, with that, the greater the efficiency of mixing.
Venturis come in a number of different sizes. Size is determined not by the size of the pipeline into which it is installed, but rather by the pressure and flow rate of the water.


Which venturi do I need?

Wassertec is an agent for Mazzei Injectors, which are made in the USA. Mazzei venturi injectors are engineered from highly chemically resistant Kynar (PVDF) and are available in sizes ranging from ½ inch to 12-inch pipe diameter. We keep stock of models in the ½ inch to 3-inch range. Other sizes are available on request.
