Structural Integrity for High-Flow Mega-Flo Systems
The Dosatron D20S Base Assembly (Part #EX-20MP005VF-HV) is the critical structural foundation for the D20S series, Dosatron’s industrial workhorse capable of handling flow rates up to 100 GPM. This "High Volume" (HV) designated assembly is engineered to withstand the significant hydraulic forces present in large-scale agricultural and greenhouse irrigation lines. As a genuine OEM replacement, this base provides the precise internal geometry and connection points required for the suction block and piston assembly to function with the proportional accuracy Dosatron is known for. Replacing a compromised base is essential for maintaining the system’s pressure rating and preventing costly chemical leaks in high-production environments.
Advanced Chemical Resistance and Precise Sealing
This base assembly comes pre-equipped with high-quality Viton (VF) seals, making it highly resistant to a broad range of concentrated fertilizers, acids, and pesticides typically used in commercial cultivation. The seals are specifically designed to maintain a perfect vacuum and pressure-tight interface, ensuring that your nutrient dosing remains consistent regardless of mainline pressure fluctuations. Built for durability and ease of maintenance, the 20MP029VF assembly allows facility managers to perform a complete bottom-end overhaul of their D20S unit, extending the service life of the injector and ensuring long-term reliability for facility-wide nutrient delivery protocols.
Key features:
- Optimized for D20S 100 GPM: Specifically designed as a direct replacement for the high-flow Mega-Flo series, ensuring perfect factory fit and function.
