Review: Fabulous 👍🏻 - I've had a couple of these, the first one lasted about five years and only failed because of a severe frost coupled with me not emptying the chamber which is easy to do, just push down on the big button at the top, ces't la vie. Anyway, second one installed and working fine. 🤞🏻 no sever frost and if so I remember to empty the chamber. I grow trees for a living and have an extensive network of irrigation pipe coupled to this dosser, so I can micro-dose the plants with liquid feed. Very effective, happy to recommend 😉 Review: Very underrated device!!! - I was originally put off buying this item because of the negative reviews, but after trying alternative ideas (such an a venturi syphon, which was utterly useless) I realised that my choice was to either pay an absolute fortune for the utter ripoff leading brand one or give this one a try. Considering that here in the UK we can return any defective item within a year if it breaks I didn't really understand what some of the other negative reviewers were complaining about since they could just return it for a full refund, so I figured I had nothing to lose by trying so I bought one and I also paid a little extra for the 2 years insurance that was offered to me by desertcart at checkout so if anything does go wrong I am covered. Well, I was extremely happy with my decision because it has worked brilliantly! I needed a system to water all my hanging baskets because it was taking ages to do them manually each day, but it also needed to add fertiliser because otherwise I would have to mix it and water them manually which would defeat the point. So plumbed in the fertiliser injector and I made sure that the input pressure was regulated down to the required amount (I have mine regulated to 1 bar, and I strongly suspect that the reason for people reporting broken seals is because they didn't bother to regulate the pressure and subjected it to the full force of the mains water, but its just a hunch). On the subject of broken seals though the box actually came with a bunch or replacement parts including seals inside it so it seems like the manufacturer has listened to the reviews and added some in each box. The unit itself seems very sturdy and as I say it has worked brilliantly and saved me a great deal of time. A well deserved 5 stars! ## Features - [Working Principle]: With flowing pressure water as power, the loss of water pressure is small, and no other power facilities are needed. In case of emergency, it can quickly dispense drugs and save a lot of manpower. - [Important Parameters]: 0.4%~4%（1:25~1:250）; Working pressure: 0.3~6 bar ( about 4.35~87 psi); inlet and outlet diameter: 3/4”(25mm), Flow range: 20~ 2500L/h (4.4 ~660.43 gallons/h) - [Accurate and Effective]: Adopt Reciprocating Dynamic Sealing Technology, has higher accuracy. unique cylinder block and piston motion area design ensures more uniform and effective mixing of liquid and medicine. - [Application]: Fertilizer irrigation, equipment maintenance, horticultural flowers, livestock breeding, environmental protection and water treatment, industrial hygiene, vehicle clarity, food processing, drinking water industry or other industries requiring a certain proportion of dilution. - [Attention]: We recommend gradually adjust up the flow of the mains water when first use to avoid broken seals due to inproper high pressure. The fertilizer injectors can only mix liquid but not gas. The pH of the solution should be in the range of 5-9. Each dosing pump will be tested with clean water before shipment. If the item you received is a little wet, please be assured that it does is a new product. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B083PRS5L2 | | Best Sellers Rank | 104,049 in Garden ( See Top 100 in Garden ) 13,080 in Mowers & Outdoor Power Tools (Garden) | | Brand | NEWTRY | | Colour | Black, Green | | Country of Origin | China | | Customer Reviews | 4.2 out of 5 stars 205 Reviews | | Flow Rate | 2500 Litres Per Hour | | Item Weight | 2.18 Kilograms | | Item weight | 2.18 Kilograms | | Manufacturer | NEWTRY | | Material | Polypropylene (PP) | | Number of Items | 1 | | Number of Packs | 1 | | Power source | Water pressure | | Product Style | Above Ground | | Style | Above Ground | | UPC | 883021663672 | | Unit Count | 1.0 count | | Usage | Animal health, food safety and sanitation, irrigation, metal processing, water treatment | ## Product Details - **Brand:** NEWTRY - **Colour:** Black, Green - **Item weight:** 2.18 Kilograms - **Manufacturer:** NEWTRY - **Material:** Polypropylene (PP) - **Maximum flow rate:** 2500 Litres Per Hour - **Number of Packs:** 1 - **Number of items:** 1 - **Power source:** Water pressure - **Style:** Above Ground ## Images ![0.4%-4% Fertilizer Injector - Image 1](https://m.media-amazon.com/images/I/71Ft1C9gpJL.jpg) ![0.4%-4% Fertilizer Injector - Image 2](https://m.media-amazon.com/images/I/71auLP7GW+L.jpg) ![0.4%-4% Fertilizer Injector - Image 3](https://m.media-amazon.com/images/I/61EvI6Z-V-L.jpg) ![0.4%-4% Fertilizer Injector - Image 4](https://m.media-amazon.com/images/I/61041YEZ0mL.jpg) ![0.4%-4% Fertilizer Injector - Image 5](https://m.media-amazon.com/images/I/61rUJ2FNicL.jpg) ## Questions & Answers **Q: Is it recommended to use an npt to bsp adapter for the uk market?** A: Hello. This product can be used with an npt to bsp adapter; the pump itself has a 6 point thread, i.e. a 3/4 inch diameter thread. **Q: Will an irrigation system still work if there isn't any fertilizer in a bucket?** A: Hello. This pump does not have any fertiliser in it and the irrigation system works. **Q: I will have a bypass around my installation for when I do not want to use any fertilizer, can just the inlet for the dosing pump be closed?** A: I have bypass too, but placed valve before and after dosing pump,just in case. But i think it would depend on pressure you have in system. Besides, i think its standard to place valves before and after, filters, pumps etc. just like everything it needs maintenance . ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fabulous 👍🏻 *by C***G on 19 June 2025* I've had a couple of these, the first one lasted about five years and only failed because of a severe frost coupled with me not emptying the chamber which is easy to do, just push down on the big button at the top, ces't la vie.

It is reliable, but the achillies heel of this pump is that the central pump washer requires regular lubricating with vegetable oil. I have used silicone grease that lasts longer! Please also note that the threads on the inlet/outlet pump are the american type & need a (expensive) pipe convertor to take them to BSP! Manufacturer Customer services were very helpful & supplied a new collar unit when my old one broke. ## Frequently Bought Together - NEWTRY 0.4%-4% Fertilizer Injector for Drip Irrigation Adjustable Water Powered Dosing Pump 3/4" NPT - NEWTRY 10pcs Springs for NEWTRY All Kinds of Water Powered Flow Dosing Pump Hydraulic Chemical Fertilizer Injectors - NEWTRY 0.4%~4% Adjustable Fertilizer Injector Water Powered Chemical Liquid Doser Dispenser 4.4~660.43 gallons/h Drip Irrigation Injector Dosing Pump for Industry Garden Hose Livestock (0.4% -4%) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/215855698-0-4-4-fertilizer-injector](https://www.desertcart.co.uk/products/215855698-0-4-4-fertilizer-injector) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-09-05*
