3SDM 1.1KW Submersible Pump For Water Supply From Wells or Reservoirs Wholesale Price 3inch 220V

1.For water supply from wells or reservoirs.
2.For domestic use,for civil andindustrial applications.
3. For garden use and irrigation.

Product description

This engineered pumping solution delivers reliable performance across water supply, irrigation, and industrial fluid handling scenarios. Capable of operating at 80m submersion depths, it handles moderately sandy water (0.25% particulate content) within confined 4" diameter spaces while withstanding +35°C fluid temperatures. The motor selection encompasses both maintainable rewinding units and sealed permanent magnet designs, available in 50Hz three-phase (380-415V) or single-phase (220-240V) variants. System integration options include traditional electromechanical starters or modern microprocessor-based controllers with energy monitoring features. The pressure-optimized pump housing design allows for optional upgrades including industrial-grade mechanical seals and customized power configurations (60Hz/alternative voltages). Ideal for residential water wells, commercial building water systems, and extensive agricultural irrigation projects requiring durable, maintenance-conscious equipment.
