Dosatron D14MZ3000 Doser | 14 GPM, 1:3000 to 1:333, 3/4 in

Why the Dosatron D14MZ3000 Doses So Low Precision beats strength here. Ratio runs 1:3000 to 1:333, or 0.03 to 0.3%, which is 1.25 to 11 mL per gallon. Flow covers 0.05 to 14 GPM on 3/4 in NPT. Anything metered in parts per million needs a range like this, because a 1:50 unit spends its whole adjustment in the first turn. Running a Nutrient Injector Off Line Pressure Water does the work. A nutrient injector of this type has no motor and no controller. Line pressure drives a piston and the piston draws concentrate in proportion to the water passing through. The ratio holds whether the line is barely open or wide. Pressure can sit anywhere from 4.3 to 85 PSI. Seals are Viton, chosen for acid and fertiliser salts, and the bypass lets plain water through for a flush. The housing is polypropylene, 21 in by 6-5/16 in, at 6 lbs. Feed water stays under 104 F. It ships with a 6 ft suction tube, strainer, weight, mounting bracket and the manual. Key Features 1:3000 to 1:333: 0.03 to 0.3%, or 1.25 to 11 mL per gallon, set on the adjustment barrel. 0.05 to 14 GPM: The ratio holds across the whole flow range, not only at full bore. No motor, no controller: Line pressure drives it, so there is nothing to wire and nothing to fail. Viton seals and a bypass: VF handles acid and salts. BP passes plain water for a flush. 3/4 in NPT, polypropylene: 21 x 6-5/16 in at 6 lbs, on 4.3 to 85 PSI. Suction kit included: 6 ft tube, strainer, weight, mounting bracket and manual. Feed under 104 F.
