Understanding Submersible Pump Operation for Boreholes in Kenya
Submersible pumps are essential for providing water from boreholes, especially in regions with water scarcity. In Kenya, many households, farms, and industries depend on boreholes to access clean water. The term submersible pump operation for boreholes in Kenya refers to how these pumps work under water to lift water from deep wells and supply it to homes or irrigation systems.
A submersible pump is placed inside the borehole, fully submerged in water. Unlike surface pumps, it pushes water to the surface instead of pulling it, which makes it more efficient and less likely to lose suction.
Types of Submersible Pumps
There are several types of submersible pumps used in Kenya. Choosing the right type is important for effective submersible pump operation for boreholes in Kenya.
1. Domestic Submersible Pumps
Domestic pumps are smaller and suitable for homes. They can lift water from shallow or moderately deep boreholes. These pumps are easy to install and require less power.
Popular Brands: Grundfos, Franklin, Pedrollo
Price Range: KES 20,000 to KES 60,000 depending on power and depth
Performance Curve: Domestic pumps usually lift water up to 60 meters and provide flow rates between 1,000 and 5,000 liters per hour.
2. Agricultural Submersible Pumps
Farms often require large volumes of water for irrigation. Agricultural pumps have higher flow rates and can operate continuously for long hours.
Popular Brands: Lorentz, Pedrollo, Grundfos
Price Range: KES 50,000 to KES 120,000
Performance Curve: These pumps can lift water up to 80 meters with flow rates from 5,000 to 15,000 liters per hour.
3. Industrial Submersible Pumps
Industries need pumps that can handle very high water volumes and operate in challenging conditions. These pumps are usually made of heavy-duty materials to resist wear and corrosion.
Popular Brands: Franklin Electric, Grundfos, Lowara
Price Range: KES 100,000 to KES 500,000
Performance Curve: Industrial pumps lift water up to 150 meters and flow rates from 15,000 to 50,000 liters per hour.
How Submersible Pumps Work
The principle of submersible pump operation for boreholes in Kenya is simple. The pump has an electric motor that drives an impeller. The impeller pushes water up through a pipe connected to the surface.
Water enters the pump through a filter or strainer to prevent debris from entering the motor. The motor is sealed to prevent water from damaging it. Because the pump is submerged, it cools itself with the surrounding water.
Key Components
- Pump Motor: Powers the impeller to lift water
- Pump Bowl and Impeller: Moves water from the borehole to the surface
- Column Pipe: Guides water and houses the electrical cable
- Discharge Pipe: Connects the pump to the surface plumbing
- Seal Kit: Prevents water from entering the motor
Installation of Submersible Pumps
Proper installation is crucial for efficient submersible pump operation for boreholes in Kenya.
- Measure Borehole Depth: Know the water table and borehole depth before selecting a pump.
- Lower the Pump Carefully: Avoid twisting the cable or dropping the pump.
- Check Electrical Connections: Ensure the motor is properly connected to a power source.
- Install a Control Panel: This panel protects the pump from overloads and dry running.
- Test the Pump: Turn on the pump and observe water flow, pressure, and motor performance.
Maintenance Tips
Maintenance ensures long life for your submersible pump. Proper care is part of successful submersible pump operation for boreholes in Kenya.
- Inspect electrical connections regularly.
- Clean pump intake to prevent clogging.
- Monitor water levels to avoid dry running.
- Check the seal and replace it if worn.
- Lubricate bearings if required by the manufacturer.

Pricing Guide
Prices in Kenya vary depending on the type and depth of the borehole:
- Domestic submersible pumps: KES 20,000 – 60,000
- Agricultural submersible pumps: KES 50,000 – 120,000
- Industrial submersible pumps: KES 100,000 – 500,000
Factors that affect prices include motor size, material quality, brand, and additional features like solar compatibility.
Performance Curves
Performance curves are diagrams that show how a pump performs at different water flow rates and pressures. Understanding these curves helps in selecting the right pump for submersible pump operation for boreholes in Kenya.
- Flow rate increases as the lift decreases.
- Each pump model has an optimum flow rate where it works efficiently.
- Curves help prevent overloading the motor.
Most manufacturers provide datasheets with flow rate, total head, power consumption, and efficiency. Always refer to these datasheets before buying.
Common Issues and Troubleshooting
Even well-installed pumps may face problems. Here are common issues:
- Pump Not Starting: Check electrical supply and motor connections.
- Low Water Flow: Inspect for clogged intake or worn impeller.
- Pump Overheating: Could be due to running dry or voltage issues.
- Noise or Vibration: Check for loose bearings or misaligned impeller.
Regular inspection prevents major damage and ensures continuous submersible pump operation for boreholes in Kenya.
