Precision Dual-Scale Metering for Hydro Series Systems
The Dosatron Injection Stem Assembly (Part #CDDI074VFHY) is the primary suction engine for the D14MZ2 Hydro series, engineered for facilities that require high-flow water management with water flow rates up to 14 gallons per minute. This assembly is uniquely configured with a dual-unit scale, displaying both percentage (%) and milliliters per gallon (mL/gal) to simplify nutrient calculations and reduce mixing errors. It is responsible for creating the volumetric vacuum required to draw concentrated additives into the mixing chamber at a consistent 1:500 to 1:50 (0.2% to 2%) injection ratio. As a genuine OEM replacement, it restores the factory-calibrated accuracy of your unit, ensuring that specialized treatments are mixed uniformly into the water stream regardless of mainline pressure fluctuations.
Industrial Viton Resilience for Acidic Environments
Equipped with high-durability Viton (VF) seals, this "Hydro" designated assembly is specifically formulated to resist degradation from acidic fertilizers, pH-down solutions, and specialized mineral oils. Unlike standard seals that can fail or swell when exposed to low-pH environments, Viton maintains its structural integrity and sealing power 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 14 GPM dosing equipment while ensuring the precise delivery of plant protection or water treatment products in demanding greenhouse and industrial environments.
Key features:
