The fluid which creates the vacuum is know as the motive fluid. The motive fluid for irrigation injectors is the irrigation water itself. Vacuum created by the venturi sucks fertilizer or chemical into motive water. Our Venturi are water driven, ie they are driven by the pressure of the main irrigation pipeline. The energy to run these devices reduces the irrigation water pressure of the water line. Applications: Fertilizer and chemical injection through drip and sprinkler irrigation systems.
