Efficient, Accurate, Durable, Easy

Crafted by a specialist irrigation brand from chemical-resistant PVC and stainless steel, the 1.5in (50mm) Venturi Fertilizer Injector uses Venturi suction to deliver accurate, pump-free dosing for drip irrigation while resisting clogging and UV degradation. It meters Fertilizer and liquid nutrients precisely with an adjustable injection rate, built-in anti-siphon safety, and easy inline installation for farms, greenhouses, and landscaping projects. Compact low-pressure operation, corrosion-resistant components, and tool-free maintenance reduce energy use and downtime, providing uniform nutrient distribution, improved crop performance, and long service life.

Material introduction

The 1.5in (50mm) Venturi Fertilizer Injector is built from lightweight, chemical‑resistant engineering plastics that withstand UV exposure and routine irrigation pressures. Critical wetted parts feature corrosion‑resistant metal fittings and durable elastomer seals (EPDM or similar) to maintain compatibility with a wide range of fertilizer solutions. This combination of sturdy polymers, resilient seals, and metal connectors delivers reliable performance up to 8 bar while keeping the unit compact and easy to install in drip irrigation systems.

FAQ

How does the 1.5in (50mm) Venturi fertilizer injector work and where should I install it in my drip irrigation system?

The Venturi injector uses the pressured water flow to create a vacuum that draws fertilizer solution from a supply tank into the irrigation mainline. Install it inline in the pressurized mainline with the flow-direction arrow aligned with water flow. For best performance place it on a straight run (a few pipe diameters of straight pipe upstream and downstream), downstream of the pump and downstream of any fine filters or pressure regulators so the injector sees clean, steady pressure. Follow the manufacturer’s orientation guidance (many allow horizontal or vertical) and secure connections to avoid air leaks.

Do I need a separate pump or electricity to run the injector? What water pressure and flow does it require?

No separate pump or electricity is required—the Venturi works off system pressure. However, it needs a minimum water pressure and flow through the 1.5in main to create suction. If system flow or pressure is too low you will see little or no draw. Check the product specifications for the exact minimum operating pressure and recommended flow range, and ensure your pump/valves supply that. If suction is weak, increasing flow or system pressure (or using a larger pump) typically restores operation.

How do I control the dosing rate and concentration when using this injector?

Dosing is a combination of the injector’s suction rate and the concentration of the stock solution in the supply tank. Some Venturi models have an adjustable metering valve to change suction rate; others have a fixed ratio. For precise dosing: (1) consult the injector’s rated injection ratio, (2) prepare a known-strength stock solution in the tank, and (3) calculate the required tank concentration based on system flow. For very precise or variable dosing, consider a proportioning pump or a venturi with adjustable ratio and flow monitoring.

Which fertilizers and chemicals can I safely inject with this Venturi?

Water-soluble fertilizers (NPK blends), many liquid nutrients, and commonly used acidifiers are typically suitable. Avoid pumping gritty, undissolved solids, viscous pastes, or concentrated corrosive chemicals unless the manufacturer explicitly states compatibility. Check the injector materials (PVC, stainless steel, seals) and the vendor’s chemical compatibility chart before use. Always mix fertilizers fully in the supply tank and strain the solution to prevent clogs and damage.

What regular maintenance is needed to keep the injector working reliably?

Regular maintenance includes: flushing the injector and suction line after each use; routinely cleaning the internal strainer and nozzle; inspecting and replacing O-rings and seals as needed; checking the suction hose and foot filter for blockages; and ensuring the supply tank is vented and free of debris. Also maintain the system’s upstream filter so particulates don’t reach the injector. Winterize according to local conditions (drain and store if freezing) and follow the manufacturer’s recommended service intervals.

The injector isn’t drawing fertilizer—what should I check first?

Common causes are insufficient flow/pressure, air leaks, clogged suction filter, blocked injector nozzle, improperly positioned suction hose, or a closed/blocked valve. Troubleshoot by: confirming adequate system flow and pressure; checking that the injector is installed in the correct flow direction; inspecting and cleaning the suction foot filter and injector strainer/nozzle; ensuring the suction hose is airtight and submerged properly (and that the supply tank is vented); and verifying there’s no backflow preventer or valve blocking suction. If problems persist, consult the product manual or supplier for model-specific checks.
