A submersible pump is one of the most important components in homes, industries, farms, bore wells, and water supply systems. Because it operates underwater, it requires specific maintenance practices to ensure long-term efficiency and prevent unexpected failures. If you are a homeowner, farmer, or industrial user, understanding how to maintain a submersible pump is essential for saving money, preventing breakdowns, and extending pump life.
At Abirami Pumps, we guide customers on maximizing pump performance through proper maintenance.
1. Perform Regular Inspection of Power Supply and Wiring
A majority of submersible pump failures start from electrical issues. Always check:
Power cable condition
Insulation damage
Loose connections
Overheating signs
Proper earthing
Make sure the pump receives correct voltage as per manufacturer standards. Voltage fluctuations reduce pump life dramatically.
2. Clean the Pump Frequently to Avoid Clogging
Over time, mud, sand, silt, and debris settle around the pump and block the suction area. This causes low water output and overheating.
To clean safely:
Remove pump from bore well/tank
Rinse casing, impeller, and strainer
Use a soft brush to clear debris
Reinstall securely
Regular cleaning increases water flow and ensures smooth operation.
3. Check Water Level and Prevent Dry Running
A submersible pump should never run without water. Dry running generates high heat and damages the motor windings, seal, and impeller.
To avoid dry run:
Install a dry run protector
Ensure adequate water level before switching on
Monitor seasonal changes in bore well levels
Submersible pumps with protectors last years longer.
4. Monitor Vibration, Noise, and Water Flow
Any change in pump behavior is an early warning sign. Watch for:
Reduced water output
Unusual noise
Increased vibration
Air/water mixture discharge
Overheating
These symptoms indicate impeller wear, clogged pipes, or mechanical issues that need attention.
5. Inspect the Non-Return Valve (NRV)
A faulty NRV causes backflow and pressure drops when the pump stops. This reduces pump efficiency and wastes energy.
Signs of a failing NRV:
Sudden pressure loss
Water draining back into bore well
Longer time to build pressure
Inspect periodically and replace when needed.
6. Lubricate Bearings and Moving Parts (If Applicable)
Many industrial submersible pumps use lubricated bearings. Follow the manufacturer’s schedule for lubrication to avoid mechanical friction and overheating.
Never over-lubricate—use only recommended grease or oil.
7. Protect Against Sand and Sediment
High sand content damages impellers and reduces life. Install:
A sand guard
Bore well strainer
Sediment filter
These accessories greatly improve pump durability.
8. Schedule Professional Servicing Annually
Even well-maintained pumps require expert inspection.
A trained technician will check:
Motor resistance
Shaft alignment
Impeller condition
Wiring
Pressure and flow rate
Annual servicing ensures long-term reliability and reduces breakdown risks.
Why Maintenance Matters
Proper submersible pump maintenance offers:
Longer pump life
Better water output
Reduced electricity costs
Avoidance of expensive repairs
Improved safety
Consistent performance
