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

Liquid and Water Jet Eductors

How do venturi water jet eductors work?

Venturis eductors 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.
