    Pressure water supply systems in remote and off-grid environments require dependable solar-powered pumping capable of delivering stable water pressure from borehole installations. This submersible pump is suitable for renewable energy applications where consistent supply and efficient operation are essential without dependence on grid electricity.

    Performance reaches a maximum head of 100 m while delivering flow up to approximately 133 L/Min at lower head conditions, derived from the performance curve peak. This allows efficient medium-head operation while maintaining stable discharge across varying demand requirements.

    A multi-stage centrifugal hydraulic design supports medium-to-high flow operation with balanced pressure characteristics across borehole applications. The polyamide impeller configuration reduces rotational mass while supporting efficient hydraulic performance and smooth water delivery throughout the operating range.

    The construction incorporates AISI 316 stainless steel for the pump and motor components, providing corrosion resistance in submerged environments. A compact 3-inch design allows installation in boreholes with a minimum diameter of 76 mm, while integrated protections including dry-running, overload, and voltage safeguards ensure dependable long-term operation.
