4SRM 3/7, 0.5HP

 Materials & Build

Pump body & motor bracket — stainless steel (AISI 304) for corrosion resistance.
Impellers & diffusers — Technopolymer for lightweight strength.
Shaft & bushes — stainless steel AISI 304 for wear resistance.
Seals & filters — stainless steel components to protect internals.
Motor — submersible, oil-filled or encapsulated electric motor designed to work fully submerged.

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.
