Venturi Fertilizer Injector Body for Drip Irrigation

Hydraulic fertilizer injection

This Venturi fertilizer injector body uses water flowing through its internal passage to create suction at the side port. A prepared liquid fertilizer solution can then be drawn into the irrigation stream. It is suited to a correctly designed injection branch serving drip irrigation or other compatible watering equipment.

Identify the component you need

The pictured product is the injector body, with water connections at its ends and a separate suction connection. Choose it when replacing the injector itself or assembling a compatible feeding branch. Agree the supplied accessories before ordering so that the tubing, intake filter, valves and connection fittings can be planned around the body.

Check the available pressure difference

Successful suction depends on water flow and the pressure difference across the injector. Connection size alone does not establish fertilizer draw rate. Check the performance information for the exact injector against the available inlet pressure, outlet pressure and irrigation flow. Allow for the pressure needed by the downstream emitters.

Connect the water and solution paths

Match the water connections, thread standard and suction port to your installation. Follow the indicated flow direction and support the pipework so that the body is not carrying unwanted pipe loads. Keep the suction connection sealed and position the solution supply according to the injector instructions. Include suitable filtration and source-water protection in the complete system.

Measure the feed before irrigating crops

Commission the assembly with water and confirm suction before introducing fertilizer. Measure the volume drawn during a timed run at normal irrigation conditions. Check concentration against the crop feeding plan and repeat the measurement after changes to flow or pressure. Flush and clean the branch as directed after use.
