The 4DSC‑A/D(HV) and 4/6DSC‑A/D(HV) series are 4″ (and 4/6″) AC/DC dual‑use wide‑voltage brushless solar pumps with stainless steel impellers, NSK bearings, and stainless steel oil cylinders for excellent corrosion resistance. They feature an AC/DC auto‑switching controller or a wide‑voltage HV controller (≤2.2kW), accepting AC 85V–280V and DC 110V–350V wide input, making them compatible with PV, grid, or hybrid power systems. Power ratings range from 750W to 1500W, delivering flows of 3.5–9.5 m³/h with maximum heads up to 203 m. Outlet sizes are 1.25″ or 2″. Each unit comes with a 2 m cable and free spare parts. Ideal for deep‑well high‑head lifting, high‑flow irrigation, and community water supply.
