Certified Precision for High-Volume Water Treatment

The Dosatron D40WL3000 Injection Stem Assembly (Part #8CD035NAF) is the primary metering component for the D40WL series, Dosatron's industrial solution for high-flow water disinfection and potabilization. This assembly is certified to NSF/ANSI/CAN 61 & 372 standards, making it the industry standard for safe chlorine injection and water sanitation. Operating at flow rates up to 40 gallons per minute, this component maintains a precise volumetric injection ratio of 1:3000 to 1:800 (0.03% to 0.125%), ensuring that water treatment protocols remain accurate regardless of pressure fluctuations in the main line.

Industrial Aflas Sealing for Alkaline Chemistries

Engineered for durability in demanding chemical environments, this assembly is equipped with specialized Aflas (AF) seals designed to resist degradation from high-pH, alkaline chemistries such as calcium hydroxide (liquid lime) and potassium carbonate. As a complete "Bill of Materials" (BOM) assembly, it provides a comprehensive field-replacement solution that restores the injector's factory-calibrated suction and mixing integrity. This ensures consistent chemical delivery for facility-wide sanitation, reducing the risk of dosing errors while extending the service life of high-flow 40 GPM dosing systems.

Key features:

• NSF/ANSI 61 & 372 Certified: Guaranteed safe for use in water potabilization and food-safety disinfection systems.
• High-Flow 40 GPM Capability: Optimized for large-scale facility operations requiring robust, reliable nutrient or chemical injection.
• Superior Aflas Seal Durability: Specifically chosen for alkaline chemistry resistance, preventing premature seal failure when using high-pH products.
• Ultra-Precise Metering: Maintains a consistent 1:3000 to 1:800 ratio for critical low-dose chemical applications.
• Complete BOM Assembly: Simplifies complex field maintenance by providing a pre-assembled metering unit that reduces labor and downtime.
