Dosatron INJECTOR 14gpm MAX 1:330 TO 1:3000 BYPASS KALREZ/VITON SEALS

Dosatron D14MZ3000 14 GPM Water-Powered Doser, Kalrez/Viton Seals – D14MZ3000VFBPIIK

The Dosatron D14MZ3000VFBPIIK is the Kalrez and Viton seal variant of the D14MZ3000 series. It operates in the same 1:3000 to 1:330 dilution range as other D14MZ3000 models but uses Kalrez (FFKM) seals in the critical sealing surfaces of the injector. Kalrez is a perfluoroelastomer that provides the broadest chemical resistance of any elastomer seal material — it is appropriate for applications where even AFLAS or Viton may be degraded by the specific chemicals in use.

The D14MZ3000VFBPIIK is water-powered and requires no electricity. The bypass allows the injector to pass water without drawing concentrate. The 3/4-inch NPT connection integrates with Lo-Flo NDS plumbing. Kalrez seals are specified when operating with aggressive chemicals — strong acids, concentrated pH adjusters, or specialty additives that fall outside Viton's or AFLAS's compatibility range.

Key Features & Benefits

• Kalrez Seal Assemblies — Broadest chemical resistance of any elastomer — handles aggressive chemicals that degrade Viton and AFLAS.
• Viton Secondary Seals — Viton used in non-critical sealing positions where Kalrez is not required.
• 1:3000 to 1:330 Dilution Range — Covers low to moderate concentrate application rates.
• 3/4-Inch NPT Connection — Compatible with Lo-Flo NDS and standard grow room irrigation plumbing.
• Bypass Included — Allows plain-water flow without removing the injector.
• 14 GPM Maximum Flow — Handles standard Lo-Flo NDS and grow room flow rates.
• Water-Powered — No electricity required.

Who Should Use This Injector

The D14MZ3000VFBPIIK is specified when the concentrates or pH adjusters being used are known to degrade standard Viton or AFLAS seals. Kalrez's broad chemical resistance makes it the appropriate seal choice for the most demanding chemical environments in professional fertigation. It is not necessary for standard hydroponic nutrient applications where Viton compatibility is sufficient.

When Are Kalrez Seals Necessary?

Kalrez (FFKM) seals are a specialized material used when other elastomers — including Viton and AFLAS — are incompatible with the chemical environment. Kalrez resists nearly all chemicals including concentrated acids, ketones, esters, amines, and steam at high temperatures. In hydroponic applications, Kalrez seals are typically specified when using concentrated pH adjusters like pure sulfuric or hydrochloric acid, or when specialty additives contain chemicals that fall outside the compatibility range of Viton. For facilities using standard liquid nutrient concentrates and phosphoric or citric acid pH adjusters, Viton seals in the standard D14MZ3000 models are chemically compatible and represent the more cost-effective choice.

Frequently Asked Questions

What seals does the D14MZ3000VFBPIIK use?

Kalrez (FFKM) seals in critical sealing positions and Viton in secondary sealing positions.

When are Kalrez seals needed over Viton?

When the specific chemical used is incompatible with Viton. Standard liquid nutrients and pH adjusters (phosphoric, citric acid) are typically compatible with Viton. Kalrez is specified for more aggressive chemical environments.

What is the dilution range?

1:3000 to 1:330.

What connection size does it use?

3/4-inch NPT.

Is electricity required?

No. The injector is entirely water-powered.
