◎ Precise Proportional Dosing

◎ Versatile Irrigation Compatible

Precise Proportional Nutrient Delivery

Designed by an agricultural equipment brand with decades of field experience, the 12V Ag Proportional Fertilizer Dosing Pump is precision-engineered for reliable, long-term performance in remote irrigation systems. Its proportional dosing technology automatically meters Fertilizer in direct relation to water flow, delivering precise, consistent nutrient application while the 12V DC power and robust, weatherproof construction enable energy-efficient operation and simple installation on tractors, pumps, or drip systems. Key features—adjustable dosing ratios, chemical-resistant materials, low-maintenance diaphragm design, easy calibration, and plug-and-play electrical connections—translate into reduced waste, improved crop uniformity, and lower operational costs for growers.

Material introduction

The 12V proportional dosing pump features a corrosion‑resistant engineered plastic body and a metal motor housing that combine lightweight construction with robust durability. Wetted parts are made from chemically compatible materials—EPDM or PTFE diaphragms, stainless‑steel or ceramic check valves and Viton seals—to withstand acidic and alkaline Fertilizer solutions without rapid degradation. External fittings and tubing use polypropylene or PE for reliable connections in greenhouse irrigation, and the compact 45×20×20 unit is shipped in a protective carton to help ensure long service life.

FAQ

What is a 12V Ag Proportional Fertilizer Dosing Pump and how does proportional dosing work?

It is a DC-powered dosing/injector designed for agricultural fertigation that delivers fertilizer or additives in direct proportion to the irrigation water volume. A control signal (from a flow sensor, irrigation controller, or pulse generator) tells the pump how much to inject so the chemical concentration stays constant regardless of changes in water flow.

Which irrigation systems and application scenarios is this pump suitable for?

It is commonly used with drip and micro‑sprinkler systems, greenhouse benches, orchards and vineyards, small pivots and reels, turf/sports fields, and off‑grid or mobile setups powered by 12V batteries or solar. It works wherever you need consistent proportional fertigation tied to the water flow.

How do I install and set up the pump for correct operation?

Mount the pump near the fertilizer tank on a stable surface. Connect the suction tube with a strainer to the tank and the discharge tube to the irrigation mainline injection point (use a tee or dedicated injector fitting). Install a flow sensor or pulse source on the mainline if required, wire the 12V power with correct polarity and a fuse, and connect the pump control to the flow sensor or controller. Prime the pump (remove air), set the desired dosing ratio on the controller, run a test irrigation cycle, and check for leaks and correct injection.

How do I calibrate and adjust the dosing ratio?

Calibrate by collecting the injected chemical over a known irrigation period and comparing it to the total water volume delivered in the same period. Example method: run irrigation for a fixed time, measure water volume and collected injected liquid, then calculate actual concentration = injected volume ÷ irrigation volume. Adjust the pump’s ratio or stroke control until measured concentration matches the target. Repeat the test after each adjustment.

What maintenance and cleaning does the pump require?

Regularly inspect tubing, fittings, seals, check valves and the suction strainer. Flush lines with clean water after each fertilizer batch or when switching chemicals to prevent crystallization or clogging. Replace wear parts (diaphragm, seals, check valves) per manufacturer guidance or if performance drops. Protect the pump from freezing and prolonged UV exposure. Keep electrical connections dry and secure.

What chemicals are safe to use and what safety precautions should I follow?

Most water‑soluble fertilizers and common liquid additives are suitable, but always check the pump’s material compatibility list for aggressive acids, oxidizers or solvents. Do not use slurries or unfiltered suspensions. Install backflow prevention (check valve or anti‑syphon) to protect the water source. Wear appropriate PPE when handling chemicals, store concentrates safely, and avoid running the pump dry for extended periods. Ensure the 12V supply is properly fused and protected from voltage spikes.
