VENTURI

CHEMICAL INJECTION WITHOUT A PUMP

Venturi effect injectors for dosing chemicalsVenturi injector fertigation component

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 fertigation without additional pump. 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.
