Dosatron chemical injectors are water-powered, so no electricity is needed, and they accurately inject chemicals into water lines.
Dosatron non-electric injectors work using volumetric proportioning, ensuring that the chemical mixture remains the same regardless of variations in pressure and flow. When water enters the Dosatron, 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, with an action similar to a hypodermic syringe. On the down stroke, the concentrate is displaced into the mixing chamber, where it mixes with the water flowing through the unit. Then the water-and-chemical mixture is discharged into the water lines. Dosatron offers two types of hydraulic motors, piston and diaphragm.
