Instantly calculate Motor HP & Stages with this borewell pump capacity calculator. Accurate estimation for V4 (Domestic) & V6 (Agriculture) pumps based on depth.
Introduction
Are you struggling to select the right submersible pump for your new borewell? A common question we get is: “I have drilled an 800-foot borewell; how much HP and which Stage motor should I select?”
Choosing the wrong pump can lead to motor burnout, low water pressure, or high electricity bills. You don’t need to guess anymore. Use our Advanced Borewell Pump Calculator below to get an instant estimation based on your depth and water requirements.

Understanding Your Results
1. Why “Total Head” is more than just Depth
Many people make the mistake of calculating pump power based only on the depth of the hole. However, to get accurate water discharge, we must calculate the Total Dynamic Head. This includes:
- Vertical Depth: The actual depth of the borewell.
- Friction Loss: As water travels up the pipe, it loses pressure due to friction against the pipe walls and bends.
- Drawdown: The drop in water level when the pump starts running.
Our calculator automatically adds a safety margin (Head Friction Factor) to ensure your pump pushes water all the way to the surface with good pressure.
2. V4 vs. V6 Pumps: Which one do you need?
- V4 Series (4-Inch): Best for Domestic/Home use. These pumps fit in standard casings and generally provide a flow rate of 1,000 to 2,000 Liters Per Hour (LPH).
- V6 Series (6-Inch): Designed for Agriculture and Irrigation. These require a wider borewell casing and high-power motors (usually 5 HP to 10+ HP) to deliver massive water flow (5,000+ LPH).
3. What are “Stages” in a Pump?
If the calculator recommends a “50 Stage” pump, it refers to the number of impellers stacked inside the pump unit.
- 1 Stage (Impeller) lifts water by approximately 15 to 30 feet (depending on the brand).
- More Stages = Higher Pressure. For deep wells (over 800 or 1,000 feet), you need more stages to push the water vertically against gravity.
Frequently Asked Questions (FAQs)
How much HP motor is required for an 800-foot borewell? For a standard home setup (V4 pump) delivering approximately 1,500 liters per hour, you typically need a motor with a horsepower range of 4.0 to 5.0 HP and approximately 45-55 stages. For agriculture (V6 pump), you would need a motor with a horsepower range of 7.5 to 10 HP to handle the higher water volume.
Does this calculator work for Openwell pumps? No, this tool is specifically designed for Submersible Borewell Pumps (V4 and V6 series) used in deep drilling.
