Dosatron COMPLETE INJECTION STEM ASSY FOR NEW D45RE8AF -HV

High-Flow Precision for 20 GPM Dosing Systems The Dosatron D45RE8AF Injection Stem Assembly (Part #CD107AF) is the essential suction and metering engine for the D45 series, a high-performance injector capable of handling water flow rates up to 20 gallons per minute. This assembly is engineered to maintain a precise injection ratio of 3% to 8% (1:33 to 1:12), making it ideal for applications requiring high-concentration nutrient or chemical delivery. As a genuine OEM replacement, the CD107AF restores the factory-calibrated volumetric precision of your unit, ensuring that concentrated solutions are mixed uniformly into the water stream regardless of mainline pressure fluctuations. Industrial Aflas Resilience for Alkaline Chemistries Equipped with specialized Aflas (AF) seals, this "High Volume" (HV) assembly is specifically formulated to resist degradation from high-pH, alkaline chemistries and aggressive cleaning agents. Unlike standard seals that can fail or swell when exposed to basic environments, Aflas maintains its structural integrity and sealing pressure under continuous-duty operation. By replacing the entire injection stem assembly, facility managers can effectively eliminate suction leaks and ensure a pressure-tight interface. This protects the operational lifespan of the 20 GPM dosing equipment while ensuring consistent delivery of specialized plant protection or water treatment products. Key features Direct D45RE8AF Series Replacement: Specifically engineered for 20 GPM high-flow injectors, ensuring an exact factory-spec fit and immediate restoration of dosing accuracy. Superior Aflas Chemical Resistance: Engineered to withstand aggressive alkaline chemicals and high-pH additives, preventing premature seal failure and suction loss. High-Concentration Dosing Precision: Maintains a consistent 3% to 8% injection ratio, perfect for specialized treatments requiring higher chemical density. Restores Volumetric Accuracy: Replaces worn internal stem components to maintain the precise suction required for high-performance facility management. Complete Maintenance Solution: Simplifies complex field repairs by providing a pre-assembled metering unit, reducing labor costs and system downtime.
