The Dosatron D20 is a water-powered injector engineered for high-performance chemical dosing across fertigation, agriculture, animal health, and industrial water treatment. As part of the innovative Mega-Flo series, the D20S is a true workhorse — delivering precise, proportional injection at flow rates up to 100 GPM, making it ideal for large farms, greenhouses, commercial irrigation, and high-volume process systems. When demand grows beyond a single unit, simply install D20S injectors in parallel to reach even greater dosing capacity.

Why Choose the D20S?

The D20S combines Mega-Flo capacity with the simplicity of water-powered operation — no electricity, no complex controls. It can be installed directly into a system or stand-alone on a set of legs, and its parallel-install capability means your dosing capacity scales with your operation. For high-volume applications that still demand precise, repeatable dosing, the D20S is Dosatron's proven workhorse.

Need even more flow?

The D20S is designed to scale. Install multiple units in parallel to multiply your dosing capacity, or explore the rest of the Mega-Flo series for higher single-unit flow rates.
