4DSC-A/D — AC/DC Brushless Solar Submersible Pump (Series overview)

The 4DSC-A/D series are AC/DC brushless submersible pumps optimized for solar-powered water supply and irrigation. These pumps are available in multiple capacity variants and are designed around a corrosion-resistant stainless-steel impeller and oil cylinder, NSK bearings and an IP-rated junction box for fair-weather and harsh-environment operation. They can be paired with auto-switching AC/DC controllers depending on power class (3–4 kW controllers for lower-power models; 5.5–22 kW controllers for larger models).
