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

How does a venturi work?
Venturis work on a principle of differential pressure.
In short, 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.
If sized and installed correctly, a venturi can achieve a gas/water ratio of 1:1. (i.e. inject 1 litre of air/ozone into every litre of water that passes through it). For Liquid dosing this ratio is maximum 1:10 (i.e. inject a maximum of 1 litre of chemical into every 10 litres of water).
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 are agents 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.
Who we are
Founded in Cape Town, January 2002, Wassertec has become the leader in ozone and ozone generation in Southern Africa.
From day one, our vision has been to design and manufacture the highest quality ozone generation systems primarily for the wine and bottled water industries. We believe that by taking care of the quality, the rest will take care of itself.
By collaborating with highly competent electrical engineers and industrial software developers, we have, over the years, created what we believe to be the best ozone systems currently available in their class.
