Product Overview
Elevated tank supply systems in remote and off-grid locations require reliable solar-powered pumping to ensure consistent water delivery at height. This submersible pump is suitable for borehole installations operating on DC energy, supporting applications where water must be lifted and stored in overhead tanks without grid dependency.
Performance reaches a maximum head of 70 m while delivering flow up to approximately 64 L/Min at lower head conditions, based on the performance curve. This allows efficient water transfer for storage and distribution systems requiring moderate head and higher flow capability.
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.
