How do I calculate the correct head requirement for my 1.5 HP submersible pump?
Calculating the correct head requirement is crucial for selecting the right 1.5 HP submersible pump. Here’s a step-by-step approach:
- Measure the static water level (distance from ground level to water surface when pump is not running)
- Estimate the drawdown (additional depth that water level drops during pumping, typically 5-15 meters)
- Measure the vertical distance from ground level to your overhead tank
- Add a friction loss factor (approximately 10-15% of the total vertical distance to account for pressure loss in pipes and fittings)
- Add a safety margin of 10-15 meters to account for seasonal water level fluctuations
Formula: Total Head Requirement = Static Water Level + Drawdown + Vertical Distance to Tank + Friction Loss + Safety Margin
Example: If your static water level is 40m, drawdown is 10m, vertical distance to tank is 15m, friction loss is 6m (10% of 65m), and safety margin is 10m, your total head requirement would be 81m. You should select a 1.5 HP pump with a head capacity of at least 85-90 meters.
For most 1.5 HP submersible pumps, the head capacity ranges from 60-120 meters depending on the model and number of stages. Choose a pump that exceeds your calculated requirement to ensure optimal performance.

Are 1.5 HP submersible pumps suitable for areas with frequent power cuts?
Yes, 1.5 HP submersible pumps can be suitable for areas with frequent power cuts, but you’ll need to consider several important factors and possibly implement additional solutions:
Challenges in Power-Inconsistent Areas
- Restart Issues: Frequent power cuts can cause repeated on/off cycles, which stress the motor and starter components
- Voltage Fluctuations: Power resumption often brings voltage spikes or drops that can damage the pump
- Dry Running: If power returns when water level is low, the pump may run dry and overheat
- Inconsistent Water Supply: Household water availability becomes unpredictable
Recommended Solutions
- Auto-Restart Controllers: Install controllers that safely manage pump restart after power restoration
- Voltage Stabilizers: Protect your pump from damaging voltage fluctuations
- Dry-Run Protection: Add sensors that prevent the pump from operating when water levels are too low
- Backup Power Solutions: Consider inverters or generators for critical water needs

What's the difference between a 1.5 HP borewell and openwell submersible pump?
Borewell and openwell submersible pumps are designed for fundamentally different water sources and applications, despite sharing the same power rating of 1.5 HP. Here’s a comprehensive comparison:
| Feature | 1.5 HP Borewell Submersible Pump | 1.5 HP Openwell Submersible Pump |
|---|---|---|
| Physical Design | Slim, cylindrical design (typically 3″-4″ diameter) | Wider, more compact design |
| Water Source | Narrow borewells (4″-6″ diameter) | Open wells, sumps, tanks, ponds |
| Head Capacity | High (60-120 meters) | Lower (30-50 meters) |
| Flow Rate | Lower flow rate (150-250 LPM) | Higher flow rate (250-400 LPM) |
| Impeller Design | Multiple stages (12-20) for high pressure | Fewer stages (3-7) for higher volume |
| Debris Handling | Limited (can handle only minimal sand/sediment) | Better (can handle some small debris and sediment) |
| Typical Application | Deep groundwater extraction | Surface water or shallow groundwater pumping |
| Example Model | Crompton 4W12BF1.5E (12 stage) | Euromolten 1.5HP Openwell |
Key Differences in Application:
- Borewell Pumps are optimized for lifting water from great depths through narrow tubes, prioritizing pressure over volume
- Openwell Pumps are designed for moving larger volumes of water from accessible sources, prioritizing flow rate over extreme pressure
Important Consideration: These pump types are NOT interchangeable. Using a borewell pump in an open well will result in lower than expected flow rates, while using an openwell pump in a borewell is physically impossible due to size constraints and would not generate sufficient pressure for deep water extraction.
Recommendation: For standard residential borewells (which are most common in Indian homes), a borewell submersible pump like the Crompton 4W12BF1.5E or CRI Zuno is appropriate. For open wells, sumps, or large tanks, the Euromolten 1.5HP Openwell Submersible would be the correct choice.
