The 4DPC‑HV series is a 4″ AC/DC dual‑use wide‑voltage brushless solar pump with corrosion‑resistant plastic impellers and NSK bearings for reliable performance. Key components (outlet, connecting fitting, oil cylinder) are available in stainless steel or brass to suit different water conditions. It is equipped with an AC/DC auto‑switching controller or a wide‑voltage HV controller (≤2.2kW), accepting AC 85V–280V and wide DC input for compatibility with PV, grid, or hybrid power sources. Performance curves show models with high flows and heads (some reaching 12–14 m³/h and over 200 m), ideal for deep‑well lifting, large‑scale irrigation, and community water supply. Free spare parts are included to reduce maintenance costs.
