Troubleshooting Deep Well Submersible Pumps


Deep well submersible pumps are vital for supplying water from underground sources, particularly in agricultural and municipal applications. However, like any mechanical system, they can encounter problems that affect their performance. Understanding common issues and their troubleshooting techniques is essential for maintaining operational efficiency.


One of the most common problems is pump failure to start. This can arise from electrical issues such as a blown fuse, tripped circuit breaker, or faulty wiring. To troubleshoot, check the power supply to ensure electricity is flowing to the pump. Inspect the control box, and replace any blown fuses. If the pump still doesn’t start, the problem may lie within the motor itself, potentially requiring professional service.


Another frequent issue is the pump running without producing water. This can indicate a few different problems, including a malfunctioning check valve, a clogged intake screen, or a drop in the water table. Start by checking the discharge piping and ensuring that there is no blockage. Inspect the check valve to verify it is functioning correctly; if it’s stuck in the closed position, it may need to be replaced. Additionally, assess the well's water level – if the water table has dropped below the pump’s intake, the pump may need to be lowered or replaced.

Low water pressure can also be a concern. If the pump is operational but delivering insufficient pressure, there could be a leak in the discharge line or the well screen may be clogged with sediment. Inspect the discharge line for any visible leaks and consider flushing the well if sediment buildup is suspected. It might also help to measure the voltage and current during operation to ensure the pump is working within its rated specifications.


Lastly, overheating of the pump is a serious issue that can lead to damaging consequences. Overheating can occur from running the pump dry or if it’s covered in debris. To address this, always ensure that the pump is submerged adequately in water. Regular maintenance, including the cleaning of the pump and the surrounding area, is crucial to prevent debris accumulation.


By identifying common issues and applying systematic troubleshooting techniques, operators can effectively address problems with deep well submersible pumps. Regular maintenance and monitoring not only enhance the reliability of the pump but also prolong its lifespan, ensuring a continuous supply of water when needed most.
