The PVT suffix indicates a PVDF head and PVDF valve with PTFE seals, a configuration commonly used for compatibility with aggressive liquids in dosing applications. This pump is intended for dosing liquids such as disinfectants, flocculants, or additives and is widely employed in water treatment, municipal, and industrial processing scenarios where accurate, repeatable flow is essential.
