    Tank filling applications in remote and off-grid locations require dependable solar-powered pumping to ensure consistent water delivery, making this submersible pump suitable for borehole installations operating on DC energy. It supports storage tank filling where steady flow and reliable operation are essential without grid dependency.

    Performance reaches a maximum head of 120 m while delivering flow up to approximately 50 L/Min at lower head conditions, based on the performance curve. This enables efficient water transfer with higher volume delivery while maintaining flexibility for varying system requirements.

    A helical rotor hydraulic design enables efficient operation across a wide working range, maintaining stable pressure while supporting smooth water movement. This configuration minimizes pulsation and ensures consistent discharge across varying operating conditions.

    The construction incorporates AISI 316 stainless steel for both 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 operation.
