Fertilizer Injector Pump



This commercial grade fertilizer injector ensures precise nutrient injection regardless of flow or pressure.

With a proportional rating of min 1% to max 10%, no power is necessary to ensure exact nutrient fertigation control in various applications including hydroponic dosing, lifestock feeding and general farming applications.

Built with UV & corrosion resistant material, the kit comes with replacement seals so you can ensure years of successful operation under various environmental conditions.  Don’t bother with other cheap venturi devices that don’t work!  We’ve tried them all, and these are the best ones on the market.

Backed by a 1 year warranty against part malfunction and in-country 24/7 Australia support.

Fertilizer Injector FAQ's

No, it’s actually very easy.   Just install it against a wall between the garden and your water mains or water tank.  The hardest bit is ensuring the right EC to your garden.   We show you exactly how to do this.   See this video

These devices have been used in large scale agriculture & farming practices for decades.     They are powered by water pressure.   As water enters through the inlet, it drives an internal suction action just like a toilet plunger.   This creates a vaccuum within the device which draws nutrient upwards from a tank below and injects this into the water flow at quantities between 0.4% to 4% of the total flow.

  • No electricity needed 
  • No pumps needed (if using water mains)
  • No reservoirs needed
  • Injects fresh nutrient every feed
  • No recirculation needed
  • Long lasting, commercial quality
  • Allows precise nutrient measurement
  • Automated & easy to maintain

This set-up is best used for larger scale operations which are cycling through more than 100 litres of water per week.   It means you spend less time managing your reservoir.   Because they rely on water pressure, they’re much more scalable then a water pump.  2 injectors are sufficient to power an entire 100 tower farm.   (Part A & Part B nutrient)

They come with a 1 year warranty on malfunction or parts replacement.   They also come with replacement seals which can be used after 1 year or so to extend the life of the device well past 2-5 years.   

Basically, this is a high quality venturi.   You can pickup small venturi devices for $20 but in our experience they don’t work!  It’s very hard to regulate the amount of suction and you end up wasting heaps of nutrient.   Also, the venturi’s we’ve tested are very tepremental.  It might work ok for a day, and then it stops sucking properly and your constantly second guessing if it’s working!    These injectors are made for commericial growers who need consistency and longevitiy.   Yes, they cost more, but they’re worth it.

Typically, the main issue is build up of mineral salt in the 6mm hose which extends into your nutrient solution.   This can be easily resolved cleaning the hose fortnightly with a wire or simply running clean water through it.   

For commercial farms, we recommend 2 x injectors.   1 for Part A & 1 for Part B.   However for smaller residential set-ups, simply use 1 injector and combing the Part A & B nutrient in one reservoir at an EC of 15.   This ensures no significant nutrient ‘lock-out’ or detrimental results.   See these results.  (All based on 1 injector and combined Part A &B at EC15)

Injector Configurations


A Hunter X controller & electric solonoid set-up is connected to 2 x fertilizer injectors each drawing seperate Part A & Part B nutrients in precise configuration which can also be controlled remotely via an app on your iphone.


A simple water tap timer is connected to the water mains, with a single fertilizer injector which draws nutrient from a combined Part A & B reservoir containing a recommended nutrient concentration of max EC15-20 for optimal stability

Without any need for power, the fertilizer injector provides precise liquid fertilizer injection of dissolved nutrient with an automated dosing system designed to work acurately in various environmental conditions.  

No matter what flow or pressure input, the dose of the output solution will always be proportional and based on the configuration of 1 to 10% solution.

    Couldn't get a venturi system to work so found this injector and it has solved the fertigation solution. We run Jadam solutions through the drip system on the espalier orchard which has just been planted out with a wide variety of heritage fruit trees and they are now commencing bud break indicating the system is working well and the young trees have good root establishment. It will also be used for our vege beds once they are finished.
    Very happy with the system which has proven to be an effective and economic solution to the fertigation headache.

    Has been flawless, and better than my expectations. One unexpected outcome has been so many of my friends being envious and being wowed by the automatic fertilising lifestyle!
    Top notch and working in the background! Thanks

    I’m using the injector to mix bleach with water for house washing etc. So far it works perfectly. I do rinse it after every use every and lubricate the seals every now and then as a precaution. I think the seals as well as the stainless spring assembly in side should last as long if not longer than a 12v pump I was previously using. I like that fact they draw straight out of the drum. So no batch mixing.

    After a quick trip to buy hose fittings from the hardware store, I had the Fertilizer Injector – Water Powered Proportional Pump up and running in no time at all. Very easy to install and set up, and with me being a first time user, I set the dosage to 2.5% to test how the vegetables react to the Powdered Hydroponic Nutrient A & B Superior Blend over the coming weeks. I'm looking forward to reaping the benefits of the injector and nutrients for many years to come. Thanks Mr Stacky for simplifying / automating the feeding process for my vegetable towers, giving me back time to spend on other interests.
