Dosatron PLUNGER ASSEMBLY FOR D8RE5 VF

The Core Suction Engine for Acidic Fertigation The Dosatron Plunger Assembly (Part #8PJ069VF) is the essential internal component responsible for creating the volumetric vacuum within the D8RE5 series injectors. Designed to handle water flows up to 40 gallons per minute, this assembly works in tandem with the motor piston to draw concentrated additives into the mixing chamber. As a genuine OEM replacement, the 8PJ069VF restores the factory-original suction power of your unit, ensuring that your nutrient solutions are blended at a consistent 1% to 5% injection ratio, regardless of fluctuations in mainline water pressure. Industrial Viton Sealing for Acid-Based Chemistries This "VF" designated model is equipped with high-durability Viton seals, making it the primary choice for growers utilizing acidic fertilizers, pH down solutions, and specialized industrial additives. Unlike standard seals that can swell or degrade when exposed to low-pH environments, Viton maintains its structural integrity and sealing performance, preventing vacuum leaks and protecting the injector from internal wear. By replacing the entire plunger assembly rather than individual O-rings, facility managers can achieve a more reliable seal and significantly reduce the labor time associated with high-flow injector maintenance. Key features Direct OEM Replacement: Specifically engineered for the Dosatron D8RE5VF series to ensure an exact factory fit and immediate restoration of 40 GPM dosing precision. Viton (VF) Seal Integration: Provides superior resistance to acidic chemicals and fertilizers, preventing premature seal degradation and suction loss in demanding environments. Restores Volumetric Accuracy: Replaces worn internal plunger components to maintain a consistent 1:100 to 1:20 injection ratio for sensitive crop or facility treatments. Heavy-Duty High-Flow Construction: Built to handle the rigorous mechanical stresses and pressure fluctuations of industrial irrigation systems operating up to 40 GPM. Complete Maintenance Solution: Simplifies complex field repairs by providing a pre-assembled plunger unit, reducing labor costs and system downtime in commercial greenhouses.
