2.For domestic use,for civil andindustrial applications.
3. For garden use and irrigation.

Product description

Designed for demanding hydrological applications, this submersible pumping system combines exceptional 80m immersion depth capability with 0.25% suspended solids tolerance. It serves potable water delivery, landscape irrigation networks, and industrial fluid transfer operations with equal proficiency. The thermal management system guarantees stable operation in +35°C liquid environments while maintaining compatibility with narrow 4" diameter wells. Motor options include serviceable rewinding models and maintenance-free encapsulated designs, powered by either three-phase 380-415V or single-phase 220-240V/50Hz supplies. Integrated control solutions range from basic magnetic starters to intelligent digital controllers with automatic fault diagnostics. Manufactured with reinforced structural casings, the pumps support optional configurations including chemical-resistant mechanical seals and alternative electrical specifications (60Hz/other voltages) for specialized installations. Particular attention has been given to hydraulic efficiency optimization for sustainable garden watering and agricultural water management applications.
