Simplify your nutrients with the D14 Series

The Dosatron D14 Series is perfect for the indoor grower. There are many different variations of the D14 to choose from and knowing the differences for your specific needs is critical!

14 GPM is the max flow rate for the D14 series.


Selecting your Dosatron Injector

Seal Options

  • Viton Seals

    Generally used for products with neutral to acidic pH. Ex: fertilizers, pesticides, acids (pH correction), supplements, surfactants

  • Aflas Seals

    Generally used for products with a higher than neutral to alkaline pH. Ex: pH up products, calcium hydroxide (liquid lime), calcium carbonate, potassium carbonate

  • Kalrez Seals

    Used specifically for Peracetic acid (also known as peroxyacetic acid, or PAA) products. Ex: ZeroTol, SaniDate, etc.

Dilution / Injection Range

The Ratio Range for doser dilution is the range of rates that doser can be adjusted to for specific amount of chemical injection into the water supply. Most dosers can be adjusted within a range of dilution amounts and other dosers have fixed dilution amounts.

EX: Dilution range of 1:500 to 1:50 gives us a percentage of solution to water of 0.2% to 2%. This essentially tells us the percentage of chemical mixture dosed into the water supply.

The ratio and percentages are also commonly view in the following units.

  • mL/gal
  • tsp/gal
  • oz/gal

D14 Ratio Ranges

Ratio Range mL/gal tsp/gal oz/gal
1:100 to 1:10 37.5 to 375 mL 7.5 to 75 tsp 1.280 to 12.8 oz
1:200 to 1:20 18.75 to 187.5 mL 3.75 to 37.5 tsp 0.64 to 6.4 oz
1:500 to 1:50 7.5 to 75 mL 1.5 to 15 0.256 to 2.56 oz
1:3000 to 1:333 1.25 to 11 mL 0.25 to 2.25 tsp 0.0425 to 0.384 oz

Dosatron Model Name Definitions.

There are several Dosatron Dosers with similar models numbers that vary by only 1 or 2 letters. BE SURE to make a selection based on your exact needs!

Units with HY in the name are specifically meant for the Dosatron NDS - Nutrient Delivery System. Units with "HY" in the model number include a SCH 80 Threaded Union to connect the injector to the other injectors/kits in-line.

Units with BY have a Bypasss option essentially taking the specific doser out of operation. Once the Bypass switch is flipped, the dosers stops the ram pump from pulling chemicals into the water line.

  • V: Identifies the type of hose (stands for Viscous)
  • BP: Units with bypass options
  • P: Identifies the type of housing (stands for PVDF or Kynar)
  • IE: Units with side injection option
  • WL: Certified by NSF to NSF/ANSI 61 Standards
  • D: Car wash units
  • HY: Hydroponic / Nutrient Delivery System units
  • AF/VF: Identifies the type of seals (AF = Aflas® or VF = Viton)
  • K: Kalrez
  • II: Identifies the region (North/Central Am. – Dosatron International, Inc.)

How the Water Powered Doser works

Dosatron water-powered, non-electric chemical injectors are the easiest, most reliable way to accurately inject chemicals into water lines. Dosatron injectors work using volumetric proportioning, ensuring that the chemical mixture remains the same regardless of variations in pressure and flow.

When water enters the injector, it triggers the hydraulic motor, which begins moving up and down inside the body of the injector.

On the upstroke, the Dosatron draws fluid up from the concentrate tank in an action similar to a hypodermic syringe.

On the down stroke, the concentrate is displaced into the mixing chamber, where it is mixed with the water flowing through the unit. Then the water-and-chemical mixture is discharged into the water lines.

  1. Water Flow
  2. Water enters the Dosatron body
  3. Concentrate is pulled up into the Dosatron
  4. Concentrate mixes with the incoming water
  5. Blended solution is discharged into the water line
