How the Water Powered Doser works

Dosatron water-powered, non-electric chemical injectors are the easiest, most reliable way to accurately inject chemicals into water lines. Dosatron injectors work using volumetric proportioning, ensuring that the chemical mixture remains the same regardless of variations in pressure and flow.

When water enters the injector, it triggers the hydraulic motor, which begins moving up and down inside the body of the injector.

On the up stroke, the Dosatron draws fluid up from the concentrate tank in an action similar to a hypodermic syringe.

On the down stroke, the concentrate is displaced into the mixing chamber, where it is mixed with the water flowing through the unit. Then the water-and-chemical mixture is discharged into the water lines.

  1. Water Flow
  2. Water enters the Dosatron body
  3. Concentrate is pulled up into the Dosatron
  4. Concentrate mixes with the incoming water
  5. Blended solution is discharged into the water line
