Quick Takeaways
- Submersible pumps are ideal for deep boreholes
- Prices range from KES 50,000 to 1M+
- Proper sizing ensures efficiency
- Solar pumps reduce operating costs
- Regular maintenance prevents failure
- Correct installation is critical
- Water demand determines pump choice
What Is a Submersible Well Pump System
Specialised water pumps designed for high performance and reliable drawing of water from deep boreholes.
A submersible well pump system is a fully submerged unit installed inside a borehole to push water to the surface. Unlike surface pumps, it operates underwater, reducing energy loss and improving efficiency.
Submersible Well Pump Complete System
- Submersible Pump
- PV modules and Connectors
- Submersible drop cable and joint
- 10m module connection cable
- DC solar isolator with MCB control provided for module isolation
- Safety rope and HDPE pipe connectors
Submersible pumps are less prone to cavitation compared to surface pumps, making them ideal for deep wells.
How Does a Submersible Well Pump Work
Submersible pumps use impellers to push water from the borehole. Impellers rotate creating pressure drop which causes the pump to draw water. Continuous impeller rotation causes the water flow to the delivery pipes.
How Much Is a Deep Well Submersible Pump in Kenya?
- Small systems: KES 50,000 – 150,000.
- Medium systems: KES 150,000 – 400,000
- Large solar systems: KES 400,000–1,000,
Types of Submersible Pumps
- Monoblock pumps: motor and pump combined, used for shallow wells
- Open well pumps: installed in open wells or tanks
How Do You Size Submersible Well Pumps
- Calculate daily water demand
- Determine flow rate (litres/hour)
- Calculate Total Dynamic Head (TDH)
Factors to Consider When Selecting a Well Pump
When selecting a well pump, consider:
- Borehole depth
- Water yield
- Power source (solar or grid)
- Pipe length
How to Install Submersible Pumps
Submersible pump installation is done by the following steps below:
- Attaching pump to pipe
- Connecting wiring
- Lowering into borehole
What Pipe to Use for Submersible Well Pumps
- UPVC pipes – UPVC pipes are often used as delivery pipes. Preferred in case the borehole water is saline.
- GI Pipes – ideal for non saline water. Highly expensive but more durable.
What Size Wire for Submersible Well Pump
A 6mm submersible pump Cable is often used.
Wire size depends on:
- Pump power
- Distance
- Voltage
Safety Rope for Submersible Well Pumps
Use a stainless-steel rope when lowering a submersible pump to prevent pump loss.
How to Test a Submersible Well Pumps
- Monitor the flow rate
- Check the power consumption rate
- Monitoring pressure of water output.
Troubleshooting Submersible Pump Issues
- Low output → clogged pipe
- No water → pump failure
- Overheating → wiring issues
How to Pull Up a Submersible Well Pump
- Turn off power
- Disconnect wiring
- Use a winch with a stainless steel rope tied to a hook to slowly pull pump
Why Solar Submersible Pumps are Popular
Solar pumps are ideal due to:
- Zero fuel cost
- Low maintenance
- Off-grid capability
Solar submersible pumps are used in remote or areas with unreliable
Maintenance Tips for Long Pump Life
- Regular inspection
- Clean pipes
- Monitor voltage
