Dosatron D14MZ2 Water Powered Doser. 14 GPM, 1:500 to 1:50

What the Dosatron D14MZ2 Does Without Power The Dosatron D14MZ2 needs no electricity at all. Line pressure drives the piston, the piston draws concentrate in proportion to flow, and the mix leaves downstream at the ratio you set. Rate holds whether the line runs at 0.05 or 14 GPM, and pressure can sit anywhere from 4.3 to 85 PSI. Dose range is 1:500 to 1:50, which is 0.2 to 2%. Reading the Model Code on a Water Powered Doser The suffix is not decoration. On a water powered doser the letters after the model tell you what you are getting, and nobody explains them. VF is Viton seals, which handle the acids and fertiliser salts that degrade a standard seal. BP is the integral bypass, so plain water can run the same line without pulling the unit. HY is the hydroponic build. Beyond the code, the numbers that matter are dose and connection. Injection runs 7.5 to 75 mL per gallon through a 3/4 in NPT body in polypropylene. It stands 19-1/8 in by 6-5/16 in and weighs 6 lbs. Feed water should stay under 104 F. The box holds a 6 ft suction tube, strainer, weight, mounting bracket, bypass and the manual. Key Features No electricity, ever: Line pressure drives the piston. Nothing to wire and nothing to trip a breaker. Proportional at any flow: The ratio holds from 0.05 to 14 GPM, so a part open valve doses the same. 1:500 to 1:50: 0.2 to 2%, or 7.5 to 75 mL per gallon, set on the barrel. VF means Viton seals: They take the acids and salts that degrade a standard seal on a feed line. BP means an integral bypass: Run plain water down the same line without pulling the unit out. 3/4 in NPT, 6 lbs: 19-1/8 x 6-5/16 in in polypropylene. Keep feed water under 104 F.
