submersible pumps troubleshooting skills
This article contains common problems related to Submersible pump and their simple solutions
No job is flawless. All industrial machinery has the potential to break down and have issues. A submersible pump is made up of a large number of parts and has a large number of additional parts fitted.
The efficient operation of all primary and auxiliary components is necessary for the pump to operate without interruption.Submersible pumps can break down occasionally for a number of reasons.
By performing regular maintenance on important components and replacing them when a problem is discovered, a significant amount of wear and tear can be reduced.
Here’s how to fix the most typical problems that arise with submersible pumps and pump machinery.
1. Problem- Motor doesn’t start
A tripped circuit breaker or blown fuse may cause the motor of a pump to stop working. A new fuse or a circuit breaker reset will take care of this problem.
The similar issue could be brought on by rusted or filthy fuse receptacles.
However, in this case, a motor intermittently ceases working. A new fuse receptacle can be installed to fix this problem.
The buildup of debris or corrosion at the pressure switch contact points on a pump results in voltage fluctuations, which damage the motor. The motor might even quit. Debris or rust removal can solve this problem.
The pump may be unable to operate correctly due to a buildup of sand or other substances nearby.
2. Problem - Imbalance in the voltage
Voltage imbalance will result from the drop-cables’ improper size. It might even be the result of each winding receiving electricity inequitably.
As a result, the motor overheats, its lifespan is reduced, and it eventually fails catastrophically. Use a cable that is the right size to avoid this problem.
By utilizing a motor that is built to function at a greater resistance level. Smaller drop cables and less full load current are needed in this design.
3. Problem - Supply line Diameter reduces
Each and every submersible pump is made to work with an input line that has a specific diameter. However, some users employ reduction couplings to attach a hose or line that is smaller than the advised diameter.
- In this case, there is a chance that the intake line will kink. It might even contract on its own. By implementing these suggestions, you can prevent this issue.
- Use an intake line that is the specified size, and make sure the intake line and discharge line are the same size.
- Make sure the intake line is straight all the way from the water source to the pump.
- Use a non-collapsible hose or a sturdy intake line.
4. Problem - Motor runs constantly
In the following situations, a submersible pump’s motor may run continuously or cycle regularly.
A leak has been found in the system. To make sure that the well-capacity of the pump is within limitations, you must check the water level and replace any broken or leaky pipes.
The pressure switch needs to be replaced. To fix the problem, you must clean the contacts and check the settings.
The check valve or screen on a pump is obstructed. To solve the problem, you must take out the obstruction.

5. Problem - sudden increase in the voltage
A submersible pump’s motor insulation is built to withstand a certain amount of voltage. However, a storm or lightning strike could be to blame for the abrupt increase in voltage.
It could harm the insulation and make the motor overheat. Even a hole in a motor’s casing could be created by lightning. To get around this issue, you must utilize an external surge protector.
6. Problem - Changes in the temperature
A submersible pump that overheats is a sign that there is a deeper issue. This issue may be brought on by a bad motor.
However, the overheating could be the result of another underlying problem that worsens in addition to rising the temperature of a pump.
The temperature changes of the pump could possibly be the result of
- improper installation
- foreign material buildup outside the motor
- Low/high voltages
- temperature of the surrounding water rising
Any of the aforementioned problems could cause a submersible pump to stop working if they are not fixed right away. Due to overheating, the water or any other cooling fluid will begin to boil and produce steam.
The pressure from the steam will cause the insulation to rupture or break down. Utilizing high-quality materials that deliver dependable service and last for years will help you avoid overheating. Making sure that each component fits properly is equally vital.
7. Problem - Motor not properly connected
A water pump’s impeller is designed to rotate in a single direction. However, if the impeller rotates in the opposite way, the pump will not work properly.
The poorly made electrical connections to the electric motor may be the cause of this issue.
In this case, you must also review the user manual when checking the setup of the electric motor. You can use it to check if the connections have been made correctly.
8. Problem - Noisy Motor
It’s important to examine the valves and make sure the flow pattern hasn’t changed if a submersible pump is very noisy. It might occur as a result of cavitation in the pump.
The excessive noise can be a pump’s response to the bubbles created during the water transfer. Due to cavitation, the pump will become quite noisy and lose efficiency. In this case, you need to make sure the driver and pump are aligned properly.
Even cavitation could be brought on by the fundamental properties of the water. In this case, it’s crucial to modify the pump in order to account for viscosity.
A submersible pump is made of several different pieces and installed with a lot of different extra parts. As a result, it could break down at any time.
It is crucial to frequently inspect the equipment’s condition and to perform maintenance or promptly replace any broken parts.
Using these suggestions, you can fix a few of the usual problems with a submersible pump. Was this article useful to you?
