Compact Fertilizer Injection Tank for Drip Irrigation

Add a refillable fertilizer reservoir to a drip irrigation feeding circuit. This compact tank works with a bypass pressure difference to move prepared nutrient solution into the water line. It suits small field blocks, nursery lines and greenhouse zones where a large stationary vessel would be unnecessary.

Choose the tank capacity

Select a 10, 20 or 30 L vessel according to the amount of fertilizer solution needed for one feeding run and the space available at your irrigation headworks. Each size is a separate purchase option; the main photograph illustrates the tank assembly style and should not be used to judge capacity. The product specification lists a maximum pressure of 0.4 MPa. Check the normal and peak pressure at the planned connection before fitting the tank.

Plan the bypass connection

The photograph shows a red vessel with a filling cap and two connection tubes leading to a valve assembly. A pressure difference between the inlet and outlet sides drives water through the tank and carries diluted fertilizer back into the irrigation supply. Match the connection threads, tube routing and any required valve or adaptor to your own system. Check the selected package contents before installation; the capacity choice by itself does not identify every accessory in the photograph.

Fill, feed and flush

Isolate the water supply and release pressure before opening the cap. Prepare a fully dissolved fertilizer solution suitable for the tank and downstream emitters, then close the vessel securely. Restore water slowly, check the joints and observe the feed while the irrigation zone runs. Flush the tank and the lines after feeding so residue does not remain in the small passages. Use the backflow protection required for your water source and installation.

Sold as one selected tank capacity. Confirm accessory and thread compatibility for your particular bypass connection.
