Hydro Systems SuperDos 20 Injector - 1in NPT - 20gpm - 2.5% Injection Rate

Mid-High Flow Non-Electric Injection with Patented Internal Mixing

The Hydro Systems SuperDos 20 Injector delivers proportional, non-electric chemical injection at up to 20 GPM through a 1in NPT connection. A patented internal mixing chamber promotes homogeneous mixing while keeping chemicals away from critical motor components, and the adjustable ratio sleeve enables quick ratio changes without tools.

A built-in on/off bypass stops injection without interrupting system water flow, making the SuperDos 20 a practical choice for facilities that need to switch between liquid chemicals and wettable soluble powder programs on the same line.

Key Features & Benefits

• Patented internal mixing chamber — ensures thorough, homogeneous chemical mixing while protecting motor components from chemical contact.
• 0.2% to 2.5% adjustable ratio — the ratio sleeve is field-adjustable without tools to match different chemical programs (1:500 to 1:40).
• Built-in on/off bypass — stops injection while maintaining water flow for easy chemical changeovers.
• Non-electric, water-driven operation — no electrical supply needed, reducing installation cost and complexity.
• 0.05 to 20 GPM flow range — proportional positive displacement keeps dosing consistent through pressure and flow variation.

Who Should Use This

Commercial greenhouse operators, nurseries, and irrigation professionals who need mid-to-high volume, non-electric injection with field-adjustable ratios for fertilization, pest management, sanitation, or pH control programs are the direct fit for the SuperDos 20.

About Hydro Systems

Hydro Systems Co. traces its Cincinnati, Ohio roots back to 1963, having concentrated on proportional dosing pump manufacturing since 1983 as part of what is now Dover's Pump Solutions Group. The SuperDos line sits at the higher-flow end of that dosing pump lineup.

Frequently Asked Questions

What is the injection ratio range?

The SuperDos 20 provides an adjustable ratio range from 1:500 to 1:40 (0.2% to 2.5%). That covers most fertilization and treatment programs without swapping injectors.

Can this injector handle wettable powders?

Yes — the SuperDos 20 is designed to handle both liquid chemicals and wettable soluble powder formulations. The patented mixing chamber keeps both types moving cleanly through the injector.

How is the injection ratio adjusted?

An adjustable ratio sleeve allows quick, tool-free ratio changes directly in the field. No disassembly is required to move between ratio settings.

What does the built-in bypass do?

The built-in on/off bypass lets the operator stop chemical injection while maintaining water flow to the rest of the system. That simplifies chemical changeovers between programs.
