Dosatron Water Powered Doser 14 GPM 1:500 to 1:50, 3/4 in

Dosatron D14MZ2 14 GPM Water-Powered Doser, 1:500-1:50 – D14MZ2VFBPHY

The Dosatron D14MZ2VFBPHY covers the 1:500 to 1:50 dilution range (0.2% to 2%), which encompasses the most common nutrient application rates for liquid hydroponic nutrients. At 0.256 to 2.56 oz per gallon (or approximately 2 to 20 mL per liter), the D14MZ2 range covers most of the standard concentrated nutrient products and is the most widely used Dosatron configuration for hydroponic nutrient delivery.

The D14MZ2VFBPHY is water-powered, requires no electricity, and features a 3/4-inch NPT connection for Lo-Flo NDS and standard grow room irrigation integration. Viton seals are standard and chemically compatible with the nutrient concentrates and pH adjusters used in most hydroponic production. The bypass allows water to flow through without dosing, and the included union provides a disconnect point for inline installation and service.

Key Features & Benefits

• 3/4-Inch NPT Connection — Standard connection for Lo-Flo NDS and grow room irrigation plumbing.
• 0.05-14 GPM Flow Range — Handles standard Lo-Flo NDS flow rates at 4.3 to 85 PSI.
• Bypass and Union Included — For plain-water flow and clean inline installation.
• Water-Powered — No electricity required.

Who Should Use This Injector

The D14MZ2VFBPHY is the standard-range Dosatron for Lo-Flo NDS and grow room fertigation. Most liquid nutrient products are used at rates that fall within the 1:500 to 1:50 range, making this the most common D14 series configuration. It is also available in 40 GPM format (D40MZ2BPVFHY) for Hi-Flo NDS and higher-throughput applications.

The D14MZ2 as the Baseline Dosatron for Standard Nutrient Programs

When designing a Dosatron-based fertigation system, most operations start with the D14MZ2 (1:500 to 1:50) because it covers the dilution range where the majority of liquid nutrient products are used at recommended rates. If the nutrient program includes products dosed at lower concentrations — such as trace element supplements at 1:1000 or silica at 1:2000 — a second D14MZ3000 injector can be added in series to handle those components without requiring the lower-concentration product to be over-dosed through the D14MZ2. Using multiple injectors in series for different concentrate ratios is standard practice in more complex nutrient delivery programs.
