Feature:1. It is installed directly on the water supply pipeline, and the water pressure is used as the power to work, without the need to power on or start the motor.2. The accurate automatic dosing ratio is not affected by the pressure fluctuation of the water flow; the amount of solution injected is proportional to the amount of water flowing into the pipeline, and the external adjustment is flexible and convenient.3. Complete quantitative dosing and mixing function. Continuous proportional injection; accurate proportional tracking adjustment; automatic uniform dilution.4. The outer shell is made of high‑quality PP, wear‑resistant, UV‑resistant, and resistant to aging. Fertilizer injector has high accuracy and long service life.5. The pump body adopts anti‑corrosion design to ensure the availability of solution and increase the service life.How to Use:1. Connect the inlet and outlet pipes on both sides of the dosing device.2. Install the hose at the bottom, because the bottom is a suction tube, and the hose is installed directly in the tube.3. Water pressure can work normally when it reaches about 2.5‑3 pressure.4. The principle of hydrodynamics.Specification:Item Type: Fertilizer InjectorMaterial: PPWeight: Approx. 1600g / 56.4ozColor: BlueProduct Size: Approx. 21.5x17cm / 8.5x6.7inAdditive Inlet Pipe Outer Diameter: Approx.12mm / 0.5inWater Inlet and Outlet Thread: G3/4 to G1 Male Thread (G1 adapter is not insta
