Precision Metering for D25 Series Fertigation Systems
The Dosatron D25RE1500 Injection Stem Assembly (Part #CD085VF) is the essential metering component responsible for regulating the accurate intake of concentrates in professional growing environments. Engineered for the D25 series—Dosatron’s widely used injector capable of handling water flow rates up to 11 gallons per minute—this assembly ensures that your solution is mixed at a constant 1:1500 to 1:500 ratio (0.07% to 0.2%) regardless of variations in system pressure. As a complete "metering part" assembly, it allows for a comprehensive restoration of the injector's lower end, maintaining the factory-calibrated volumetric precision required for high-performance crop management.
Industrial Viton Sealing for Acidic Chemistries
This specific assembly is equipped with high-durability Viton (VF) seals, making it the primary choice for applications involving acidic fertilizers, pH down solutions, and specialized industrial mineral oils. The "High Volume" (HV) construction is built to withstand the mechanical stresses of continuous-duty fertigation, where consistent delivery of nutrients or plant protection products is critical to plant health. By replacing the entire injection stem assembly, facility managers can effectively eliminate suction leaks and ensure a pressure-tight interface, preventing air from entering the nutrient stream and ensuring a reliable, maintenance-free operation.
