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

• 1:500 to 1:50 Dilution Range — 0.2% to 2% — the range covering most standard liquid nutrient programs.
• 0.256 to 2.56 oz per Gallon — Application rate in US imperial units.
• Viton Seal Assembly — Chemical compatibility with standard hydroponic nutrients and pH adjusters.
• 3/4-Inch NPT Connection — Sized for Lo-Flo NDS and standard grow room irrigation plumbing.
• 0.05-14 GPM Flow Range — Handles standard Lo-Flo NDS flow rates at 4.3 to 85 PSI.
• Water-Powered — No electricity required — operates from incoming water pressure.

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.

Frequently Asked Questions

What is the dilution range of the D14MZ2VFBPHY?

The dilution range is 1:500 to 1:50 (0.2% to 2%). That covers the rate most standard liquid hydroponic nutrient products are used at.

Is the D14MZ2VFBPHY the right model for standard liquid nutrients?

Yes, most liquid hydroponic nutrient programs fall within the 1:500 to 1:50 range at recommended rates, making this the most commonly used D14 configuration. It is the default starting point for a new fertigation build before adding specialty injectors for other products.

What is the 40 GPM equivalent of this injector?

The Dosatron D40MZ2BPVFHY (DS40GPM7.5BSVTU) is the 40 GPM Hi-Flo equivalent. Choose it instead when your facility's flow rate exceeds what a 3/4-inch Lo-Flo injector can handle.

When would I add a second injector in series with this one?

Add a second D14MZ3000 injector in series when your nutrient program also includes products dosed at lower concentrations, such as trace supplements around 1:1000 or silica around 1:2000. That avoids forcing a low-dose product through an injector calibrated for standard-strength nutrients.

What is included?

Mounting bracket, suction hose, bypass, union, and weighted strainer. That's the complete hardware set for a standard inline installation.
