Specifications: Inlet/outlet thread: 3/4'' Material: POM Size: See photos Flow range: 0.65-2.42 m3/h Work pressure: 0.7-9.5bar Self-priming capability: 9-92L/h Package Includes: 1 Pc 3/4 Inch Venturi tube, 1 Pc Irrigation Water Hose, 1 Pc Flow Control Switch, 1 Pc Metal Mesh Filter Working principle: 1, Venturi-type fertilizer and irrigation system irrigation at the entrance of the water supply control valve installed in parallel, the use of control valve will be small, the formation of the control valve before and after the pressure difference, you can dissolve in the water inhalation into the Venturi And then into the water supply pipe. 2, The use of water through the Venturi tube produced by the vacuum suction, the fertilizer solution from the exposed fertilizer bucket evenly inhaled piping system for fertilization. Make your operation more convenient and simple. 3, If the fertilization concentration is stable, no additional power, more savings your time and resources! 4, the scope of application: greenhouse and other small area of fertilization. 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.
