Pump failures can cause serious disruptions to your business or facility. It is important to recognize the symptoms of pump failure and know the causes, prevention, and repair techniques. This blog provides an overview of pump failure and examines the signs to look out for, the most common causes, and the ways to prevent, diagnose, and repair a pump failure.
Symptoms of Pump Failure
To better understand the various signs of pump malfunction, it’s important to be aware of the five primary symptoms: Unusual Sounds/Vibrations, Changes in Pressure, Leaks Around the Pump, Short Cycling, and Excessively High Temperature.
Unusual Sounds/Vibrations
When it comes to diagnosing potential pump failure, one of the signs to look out for is any unusual sounds or vibrations. Abnormal noises and vibrations can indicate that the pump is not working correctly, and should be investigated further. Common sounds to look out for include grinding, rattling, squealing, or even humming. These sounds can be caused by a number of issues, such as worn bearings, misaligned impellers, or clogged components. Vibrations can also be caused by similar issues, including misalignment, out of balance impellers, and cavitation due to low flow.
If you notice any of these symptoms, it is best to shut down the system and investigate the cause. Early detection and correction of the issue can help to prevent further damage and costly repairs. If you are unsure of the cause, it is best to contact a professional for assistance.
Changes in Pressure
Changes in pressure are one of the most common symptoms of pump failure. If you notice a sudden decrease or increase in pressure, it could be an indication that something is wrong with your pump. For example, if you notice that the pressure in your water system has dropped significantly, then it could be a sign of a broken pump or a clogged filter.
Similarly, if the pressure suddenly increases, it could be a sign of a broken valve, a worn seal, or a blocked impeller. In either case, it is important to get the problem checked out by a professional to ensure that your pump is functioning properly.
Leaks Around the Pump
Leaks around the pump can be a telltale sign of pump failure, as the pump is designed to keep the system sealed and pressurized. When the pump begins to fail, it can no longer provide the necessary pressure, leading to leaks. In many cases, these can be identified by the presence of liquid or gas seeping from the pump or its connections. This leakage can also be accompanied by other signs of pump failure, such as a decrease in the pump’s performance, an increase in the noise or vibration from the pump, or a change in the system’s operating temperature. If a leak is detected, it is important to take the necessary steps to address the issue as quickly as possible, as it can lead to further damage to the pump and the system.
Short Cycling
Short cycling is one of the more common symptoms of a pump failure. This occurs when the pump starts and stops rapidly, without completing its normal cycle. This can cause the pump to overheat, leading to a breakdown. Short cycling can also be caused by a malfunctioning pressure switch, a faulty relay, or a blockage in the pipes. In any of these cases, it’s important to have the pump serviced by a professional to prevent further damage.
Excessively High Temperature
One of the most common symptoms of a pump failure is an excessively high temperature. When a pump is not functioning properly, it may struggle to move fluids, resulting in increased friction and heat buildup. This can cause the pump to overheat, leading to a significant rise in the temperature of both the pump components and the fluids being moved.
It is important to keep a close eye on the temperature of your pump. If the temperature of the pump rises above the normal operating range, it is a sign that the pump is not functioning optimally, and could be a symptom of a potential pump failure. If you notice an excessively high temperature, you should take steps to address the issue immediately, as it could be an indication that the pump needs repair or replacement.
