Review: Easy order and delivery - These are good units, but I wish that they would last longer than 18-24 months. The rebuild kits are available but the unit is hard to clean first. Review: Always a good one - I ordered this through desertcart because it was a better deal than my sales rep I have. Always. Good injector for professionals. Wish they had service more than sending them back. It’s too expensive ## Features - Dilution Range: 1:500 to 1:50 (.02% to 2%) - Water Flow Range: 0.05 to 14 GPM - Operating Pressure Range: 4.3 to 85 PSI - Dimensions: 19 1/18" x 6 5/16" Connection size: 3/4" NPT - Weight: 6 lbs ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07HJFM6TC | | Best Sellers Rank | #77,293 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #4 in Lab Dosing Pumps | | Brand | Dosatron | | Brand Name | Dosatron | | Color | Black | | Customer Reviews | 4.4 out of 5 stars 67 Reviews | | Flow Rate | 14 gpm | | Included Components | Doser | | Item Dimensions L x W x H | 22"L x 6.75"W x 5.75"H | | Item Type Name | Consistent Dispenser | | Item Weight | 4.4 pounds | | Manufacturer | Dosatron | | Manufacturer Part Number | D637922-D14MZ2 D14MZ2VFII | | Manufacturer Warranty Description | Limited Manufacturers Warranty.

It has all kinds of settings on it so it should work for you. I think your pressure should be OK. **Q: Can I use this Dosatron for humic acids ?** A: We do not use humid acid in ours. Humid acid has some solid materials in it that may require constant agitation to keep it stirred up. The dositron has a screen but not sure if it would clog or reduce effectiveness. We have used humic acid in a sprayer system with an agitator. Sorry this is not a better answer. Best of luck! **Q: Does it come with a bypass switch?** A: I don’t think so, but I never received my order. Was shipped????? But never received it and no tracking info???? **Q: Can I use this to inject soda ash mixture to my well water?** A: does the ash dissolve completely ? If so you could use it but if it has granules in it the pump will wear out ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy order and delivery *by K***O on April 14, 2026* These are good units, but I wish that they would last longer than 18-24 months. The rebuild kits are available but the unit is hard to clean first. ### ⭐⭐⭐⭐⭐ Always a good one *by N***I on June 7, 2024* I ordered this through Amazon because it was a better deal than my sales rep I have. Always. Good injector for professionals. Wish they had service more than sending them back. It’s too expensive ### ⭐⭐⭐⭐⭐ Very nice addition to the greenhouse *by A***O on March 26, 2022* We purchased this to go in our new greenhouse. We have been using the exact same model in our old greenhouse for many years and they work great. On the few occasions that we needed customer support we were very happy with the level of service that we received from the manufacturer. ## Frequently Bought Together - DOSATRON D14MZ2 D14MZ2VFII Water Powered DOSER 14GPM 1:500-1:50 D637922 - Dosatron Nutrient Delivery System - Mixing Chamber Kit --- ## 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.za/products/83606093-d14mz2-d14mz2vfii-water-powered-doser-14gpm-1-500-1-50](https://www.desertcart.co.za/products/83606093-d14mz2-d14mz2vfii-water-powered-doser-14gpm-1-500-1-50) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-04*
