Submersible Water Pumps: The Complete Guide
What is a Submersible Water Pump?
A submersible water pump is a pump that goes inside the water — usually inside a borewell or an open well. Unlike a regular monoblock pump that sits above ground and pulls water up, a submersible pump pushes water up from below. This makes it far more efficient, especially for deeper water sources.
Because the motor is sealed and sits underwater, it stays cool naturally and runs quietly — which is why submersible pumps tend to outlast surface pumps when used correctly.
When Do You Need One?
Deep Borewells
Especially anything deeper than 25 feet — a surface pump simply can't pull water efficiently from that depth.
Farm Irrigation
Large acreage needs steady, high-volume flow that only a submersible setup can sustain.
Multi-Floor Buildings
Consistent pressure across floors, without the head-loss issues surface pumps run into.
Deep Open Wells
When the well is too deep for a surface pump to prime and pull from reliably.
For regular home use with an overhead tank and shallow sump, a self-priming monoblock pump usually works fine. But for borewells, submersible is the way to go.
How Does It Work?
The pump sits submerged inside your borewell. Switch it on, and it pushes water up through a pipe connected to your overhead tank or supply line. Water itself helps keep the sealed motor cool — which is exactly why running it dry damages it so quickly.
Polter Pumps offers both variants across its submersible pump range — from the compact V3 to the heavy-duty V8.
Choosing the Right Pump
1. Borewell Depth
Rough guide only — the deeper the borewell, the more powerful the pump needs to be. See the full submersible pump range.
2. Water Requirement
A household of 4–5 people typically needs around 500–1000 litres per day. A farm with 3–5 acres under irrigation needs significantly more. Match the pump's flow rate (LPM) to your daily requirement.
3. Power Supply
Smaller pumps (under 2 HP) usually run on standard single-phase home supply. Larger pumps (3 HP and above) typically need three-phase power — check your supply before buying.
Submersible Pumps for Agriculture
For farmers, a submersible pump is often the most reliable solution for borewell-based irrigation. The V4 and V5 range is widely used across farms in:
Looking at solar-powered irrigation? Our pumps are compatible with solar setups too, cutting electricity costs significantly over time — read our guide on solar water pumps for agriculture.
Submersible vs. Monoblock — Which One?
If your water source is a borewell deeper than 25 feet, always go with a submersible pump. For open wells, check our open well pump range — designed specifically for that purpose.
How Long Does a Submersible Pump Last?
A good quality submersible pump lasts 8–10 years with basic maintenance. Key things that extend pump life:
- Never run the pump dry — always ensure water level is above the pump
- Check the power supply regularly — voltage fluctuations can damage the motor
- Inspect the cable and connections once a year
- Use a starter or control panel with overload protection
All Polter Pumps submersible pumpsets come with a 1-year manufacturer warranty and copper wound motors built for Indian power conditions.

Common Questions
Can I install a submersible pump myself?
Not recommended. Installation involves lowering the pump into the borewell, connecting pipes, and setting up the electrical panel. Always get it done by a qualified technician.
What happens if the pump runs dry?
The motor overheats and can burn out quickly. Always install a dry-run protection switch or water level controller if possible.
Which submersible pump is best for a 200-foot borewell?
200 feet is approximately 60 metres. The V4-100MM Pumpset handles up to 180 metres of head — a solid choice for this depth.
Does Polter Pumps have dealers in Delhi NCR?
Yes. We have our Delhi office at Najafgarh, New Delhi, and a growing dealer network across Delhi NCR. Check our dealer page or call +91 9821698852.
