## Overview

The NEWTRY Fertilizer Injector is a water-powered dosing pump designed for precise chemical injection with an adjustable range of 0.4% to 4%. It operates efficiently without electricity, supports flow rates from 0.09 to 11 GPM, and withstands pressures between 2.9 and 87 PSI. Engineered with advanced sealing and piston technology, it ensures uniform mixing for applications spanning irrigation, livestock, industrial sanitation, and water treatment.

## 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

## 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.
- [Accurate & Effective]-Adopt reciprocating dynamic sealing technology, this dosing pump has higher accuracy. Unique cylinder block and piston motion area design ensures more uniform and effective mixing of liquid.
- [Application]-Animal Health, food safety & sanitation, irrigation, metal processing, nutrient delivery system, printing, vehicle wash, water treatment, dilution solutions or other industries requiring a certain proportion of dilution.
- [Attention]-The fertilizer injectors can only mix liquid but not gas. The pH of the solution should be in the range of 1-10. 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.
