Reasons And Treatment Methods For Abnormal Sound Of Submersible Pump Starting

Mar 22, 2024

Submersible pumps are widely used to pump water from wells, boreholes, and other sources. These pumps are designed to be submerged in water and are used for various applications such as irrigation, domestic water supply, and industrial uses. However, sometimes when these pumps are started, they produce unusual noises, which can indicate a problem. In this article, we will discuss the reasons for the unusual sounds in submersible pumps and the methods to deal with them.

Reasons for Unusual Sounds in Submersible Pumps

1. Air in the Pump：When there is air in the pump, it can cause unusual sounds when the pump is started. The air can enter the pump if the water level in the well or borehole is too low. This can cause the pump to become noisy and inefficient.

2. Damaged Impeller：A damaged impeller can also cause unusual noises in submersible pumps. The impeller is the part of the pump that rotates and creates pressure that moves water through the pump. If it becomes damaged, then the pump will make loud noises when it is started.

3. Loose Motor：If the motor of the submersible pump is loose, it can also cause unusual sounds. This can occur if the motor has become detached from the pump housing, or if there is a loose connection between the motor and the impeller.

Methods to Deal with Unusual Sounds in Submersible Pumps

1. Check the Water Level：If the water level in the well or borehole is too low, then the pump will suck air, which can cause unusual sounds. To fix this, check the water level and make sure that it is adequate for the pump to work properly.

2. Replace the Impeller：If the impeller is damaged, then it needs to be replaced. To do this, the pump will need to be disassembled, and a new impeller will need to be installed.

3. Secure the Motor：If the motor is loose, then it needs to be secured properly. This can be done by tightening any loose screws or bolts that are holding the motor to the pump housing.


Submersible pumps are an important piece of equipment that can be used for various applications. However, when they produce unusual sounds, it can be an indication of a problem. By understanding the reasons for these sounds and using the appropriate methods to deal with them, submersible pumps can continue to work properly and efficiently.
