NEWTRY Water-Powered Fertilizer Injector for Drip Irrigation 3/4" NPT Adjustable 0.4–4% Dosing

This compact, mechanical dosing pump attaches to a 3/4" NPT line and uses the flow of water to proportionally draw and inject concentrated liquids into drip irrigation or circulation systems. Designed for stable volumetric mixing, the unit keeps the concentration consistent across varying water pressures and flow rates. It is suitable for agricultural nutrient delivery, sanitation systems, vehicle wash dilution, and other industrial applications that require reliable liquid metering.

How precise is the NEWTRY injector when mixing solutions?

The injector uses a reciprocating piston and dynamic sealing design to deliver steady, repeatable dosing with minimal drift. Its volumetric proportioning method means the set ratio remains constant even if pressure or flow changes.

• Adjustable percentage range: 0.4%–4% (ratio 1:250–1:25)
• Flow capabilities: 0.09–11 GPM, suitable for small to medium systems
• Works across 2.9–87 PSI operating pressure

Will this pump work without electricity and how is it installed?

This model is water-driven—no external power source required—so it installs directly into the water line and uses the moving water to operate the dosing mechanism. Connection is standard 3/4" NPT for common plumbing fittings, making field installation straightforward.

• 3/4" NPT threaded inlet and outlet for easy plumbing
• Inline installation reduces footprint and avoids extra wiring
• Flow through the unit will slightly decrease due to internal hydraulics

What chemicals and fluids can I safely dose with this injector?

The pump is built for liquid solutions only; it cannot meter gases or highly volatile mixtures. It performs best with neutral to mildly acidic or alkaline liquids—recommended pH range is 5–9—and is commonly used for fertilizers, cleaners, and treatment chemicals.

• Suitable for fertilizers, sanitizers, detergents, water-treatment chemicals
• Not recommended for gases, foaming agents, or solids-laden slurries
• Each unit is pressure-tested with clean water before shipment

How durable and maintainable is the NEWTRY dosing pump?

Constructed for repeated use, the pump’s piston/cylinder geometry and sealing approach improve longevity and dosing uniformity. Routine checks and using compatible liquids will keep performance steady; minor dampness from factory testing is normal and does not indicate prior use.

• Reciprocating dynamic seals minimize leakage and wear
• Simple service access for cleaning or replacing seals and pistons
• Tested before shipment; light moisture from testing is expected

Who this is for: The NEWTRY 0.4%–4% fertilizer injector is aimed at growers, horticultural technicians, small-scale commercial irrigators, and facility managers who need a dependable, electricity-free metering solution. It suits anyone wanting consistent dilution ratios across variable water supplies—ideal for nutrient delivery in drip systems, sanitation and wash stations, and other applications requiring accurate liquid dosing without complex electronics.
