If you are dealing with a borewell at home or on your farm, you have probably heard the term submersible water pump more than once. But what exactly is it, how does it work, and how do you pick the right one? This guide covers everything in simple language — no technical jargon, just what you actually need to know.

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. That is why submersible pumps tend to last longer than surface pumps when used correctly.

When Do You Need a Submersible Water Pump?

You need a submersible pump when:

• Your water source is a borewell — especially one deeper than 25 feet
• You need water for irrigation across a large farm
• You have a building with multiple floors that needs consistent water pressure
• Your open well is deep enough that a surface pump cannot pull water efficiently

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 a Submersible Pump Work?

The pump sits inside your borewell, submerged in water. When you switch it on, it pushes water up through a pipe connected to your overhead tank or direct supply line. The motor is sealed in a watertight casing — water actually helps keep it cool, which is why running it dry can damage it quickly.

Most submersible pumps are either oil-filled or water-filled:

• Oil-filled — Motor is cooled by oil inside the casing. Works well for clean borewell water.
• Water-filled — Motor is cooled by water. More eco-friendly, and handles slightly sandy water better.

Polter Pumps offers both variants across its submersible pump range — from the compact V3 to the heavy-duty V8.

How to Choose the Right Submersible Pump

Three things decide which pump you need:

1. Borewell Depth

The deeper your borewell, the more powerful the pump needs to be. As a rough guide:

• Up to 42 metres — V3-75MM Submersible Pumpset (0.5 HP to 2 HP)
• Up to 180 metres — V4-100MM Submersible Pumpset (0.75 HP to 7.5 HP)
• Deeper borewells — V5, V6, V7, V8 range for higher head and flow requirements

2. Water Requirement

How much water do you need per day? A household of 4 to 5 people typically needs around 500 to 1000 litres per day. A farm with 3 to 5 acres of irrigation needs significantly more. Match the flow rate (LPM) of the pump to your daily requirement.

3. Power Supply

Smaller pumps (under 2 HP) usually run on single-phase power — standard home supply. Larger pumps (3 HP and above) typically need three-phase power. Check your power supply before buying.

Submersible Pump for Agriculture

For farmers, a submersible pump is often the most reliable solution for borewell-based irrigation. The V4 and V5 range from Polter Pumps is widely used across farms in Gujarat, Rajasthan, Delhi NCR, and Punjab.

If you are looking at solar-powered irrigation, our pumps are also compatible with solar setups — reducing electricity costs significantly over time. Read more in our guide on solar water pumps for agriculture.

Submersible Pump vs Monoblock Pump — Which One?

This is the most common question people ask:

• Monoblock pump — sits above ground, pulls water from a sump or tank. Good for shallow sources and home use. See our monoblock pump range.
• Submersible pump — goes inside the borewell, pushes water up. Essential for deep borewells and high-flow requirements.

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 to 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. Submersible pump 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.
