## Overview

The NEWTRY Fertilizer Injector is a water-powered dosing pump delivering precise chemical injection from 0.4% to 4% concentration with a flow capacity up to 660 gallons per hour. Designed for professional irrigation and industrial applications, it ensures consistent mixing without electricity, operating efficiently across a wide pressure range (2.9-87 PSI). Built with durable ABS material and advanced piston technology, it supports diverse uses from garden drip irrigation to livestock and water treatment, making it an essential tool for modern sustainable management.

## Description

Product Description This is a water-powered doser device powered by the water dosage so when the water flow is small it will not work properly. It is recommended to check the water pressure. Uses: fertilizer and water irrigation, maintenance, garden flowers, rearing, environmental protection and water treatment, industrial hygiene, vehicle cleaning, food processing, printing industry or other industries that need to be diluted. Functionality: 1. The proportional pump takes the flowing pressure water as current, with little water pressure loss, without any other power plants. 2. It uses the hydropower of the proportional pump as the motor that operates the piston and the connecting rod inside the proportional pump, sucks up the liquid additive directly and makes it dissolve in the water flow. 3. This device moves up and down in a cylinder. When pushing the water, it uniformly sucks the additives charged at the bottom of the reservoir in the water flow through a pipe. 4. Repeat the movement up and down until the effect is achieved that the additive is added to the flowing water evenly and constantly. Parameters: Proportional Range: 0.4%·4% (1:25~1:250) Flow Range:20~2500L/h Working water pressure: 0.3~6 bar (about 4.35~87psi) Inlet and outlet diameter: 25mm Continuous work: >100T Flow Temperature: 4~30℃ Note: we will ship the product to you as soon as possible If you have any questions, please feel free to contact us

Review: Great for drip gardens - Works great for low-flow drip applications where cheap venturis don’t work.
Review: Ottimo - Funziona bene e permette di nutrire le piante con concime liquido direttamente durante l'irrigazione. Per me che uso compost liquido concentrato è comodissimo.

## Features

- [Important Parameters]-Percentage Range: 0.4 to 4% | Ratio Range: 1:250 to 1:25 | Flow: 0.09 to 11 GPM | Pressure: 2.9 to 87 PSI | Connection Size: 3/4" NPT
- [Working Principle]-Water powered fertilizer injector, no electricity is needed. It uses volumetric proportioning, ensuring that the chemical mixture remains the same regardless of variations in pressure and flow. The water flow rate will be reduced when going through the fertilizer injector.
