Venturi Injectors


Chemical Injection without a pump

Venturi injectors are an efficient way to introduce liquids or gases into water. They are ideally suited for chemical dosing, water aeration, ozone dosing and fertigation without the need for an additional pump. The Venturi operates on the principle of pressure differential. In simple terms, water enters the Venturi at a higher pressure than the pressure at the outlet. This pressure difference creates a vacuum at the side suction port of the device. As a result, air, ozone or liquid is drawn into the main water flow. The greater the pressure difference, the stronger the vacuum and, consequently, the higher the mixing efficiency.
