4SRM 3/10 1 HP

A 4‑inch borehole submersible pump with 1 HP power, designed for lifting clean water from wells and boreholes. It delivers up to 7–8 m³ per hour and can pump water to a maximum head of around 50–55 meters. Ideal for household water supply, small-scale irrigation, tank filling, and pressure-boosting systems, it features a stainless-steel body and multistage impellers for reliability and efficiency

  • Motor: Submersible motor designed to operate fully under water with IP68 protection.
Installation Considerations

Fully submerge and suspend vertically in the borehole using a strong rope or rod.

Use proper submersible cable and grounding with a dedicated electrical supply.

Install rigid discharge pipe with check valve and avoid dry running.

Ensure clean water with minimal sand and maintain access for maintenance.
