Dosatron INJECTOR 14GPM MAX 0.25 TO 2.25 TSP/GAL W/ 1 UNION

Dosatron D14MZ3000 14 GPM Water-Powered Doser, 1:3000-1:333 – D14MZ3000VFBPHY

The Dosatron D14MZ3000VFBPHY is a 3/4-inch 14 GPM water-powered proportional injector in the D14MZ3000 series. It covers the 1:3000 to 1:333 dilution range (0.03% to 0.3%), making it suitable for concentrates applied at low rates. A distinctive feature of this model is the custom injection scale: rather than displaying only percentage or ratio markings, it shows the dosing rate in milliliters per liter and teaspoons per gallon — the units used in hydroponic product labels — making it easier to set the injector directly from the product's feeding schedule without unit conversion.

The D14MZ3000VFBPHY uses Viton (FKM) seal assemblies, which are chemically compatible with the broad range of liquid nutrient concentrates, pH adjusters, and additives used in hydroponic production. The 3/4-inch NPT connection integrates with Lo-Flo NDS systems and standard grow room irrigation plumbing. The included bypass allows water flow without dosing, and the included union simplifies inline installation and future injector removal.

Key Features & Benefits

• 1:3000 to 1:333 Dilution Range — 0.03% to 0.3% — covers low-concentration nutrient and additive application rates.
• mL and tsp/gal Dial Scale — Custom injection scale reads directly in the units used on hydroponic product labels.
• Viton Seal Assembly — Chemical compatibility with standard nutrients, pH adjusters, and additives.
• 3/4-Inch NPT Connection — Sized for Lo-Flo NDS and standard grow room irrigation plumbing.
• 0.05-14 GPM Flow Range — Handles low to moderate flow rates at 7 to 85 PSI.
• Bypass and Union Included — Bypass for plain-water flow; union for clean inline installation and service.
• Water-Powered — No electricity required — operates from incoming water pressure.

Who Should Use This Injector

The D14MZ3000VFBPHY is for growers who dose concentrates in the 1:3000 to 1:333 range — most single-part and two-part liquid nutrient products fall within this range at recommended rates. The custom mL/tsp-per-gallon scale is particularly useful when following manufacturer feeding schedules that specify dosing in those units.

The Custom Injection Scale Explained

Most Dosatron models are calibrated with a percentage or ratio scale, requiring the grower to convert the product label's dose recommendation from mL per liter or tsp per gallon into a percentage before setting the injector. The D14MZ3000VFBPHY eliminates this step with a scale that reads directly in the same units. For example, if a nutrient label calls for 5 mL per liter, the grower sets the injector to 5 mL/L rather than calculating that 5 mL/L equals approximately 0.5%, which equals a 1:200 ratio. This reduces the likelihood of dosing errors from unit conversion mistakes.
