1. What is a Submersible Pump?
- A pump with a hermetically sealed motor that operates fully submerged underwater in a borewell, sump, or well.
2. How does a Submersible Pump work?
- It uses impellers to push water up toward the surface (rather than pulling/sucking it), which makes it highly efficient and quiet.
3. What do V4, V6, V8, etc. stand for?
- The 'V' series indicates the compatible borewell diameter:
- V3 / V4: For 3-inch or 4-inch borewells (domestic & light farming)
- V6 / V7 / V8: For 6, 7, or 8-inch borewells (heavy agricultural & industrial supply)
4. What is the difference between Radial Flow and Mixed Flow?
- Radial Flow: High pressure/head capacity — best for pushing water out of very deep borewells.
- Mixed Flow: High volume discharge — best for pumping large quantities of water at medium depths.
5. Can Submersible Pumps run on Solar Power?
- Yes, many models can connect to solar controllers and PV arrays for cost-effective, off-grid irrigation.
6. What causes a submersible pump to stop working?
- Common issues: Low voltage / phase loss, dry running (water level dropping below the pump), damaged cable, or blocked impellers due to mud/sand.
