Even though centrifugal pumps are designed in a way that they can handle high temperatures and pressures, they still need to be resistant to problems. Therefore, being prepared for issues beforehand is always a good idea. This article contains all possible problems your centrifugal pump may face and the solutions you might need to come up with to solve them.
Problem 1 – Unusual Sounds and Vibrations
Something might be wrong with your centrifugal pump if you notice unusual sounds and vibrations. The cause of this can either be some solid particles stuck inside the pump or failed bearings.
Solution – Check if there are any particles stuck in your pump. If yes, remove it. If the sound and vibration persist, your centrifugal pump may be facing cavitation, requiring professional assistance.
Problem 2 – Leakage in Pump
Leakage occurs when the pump’s seals and joints tend to get loose. This loosening results in liquids and material flowing out of the pump.
Solution – If your pump faces leakage, check the seals and joints and make sure you tighten them.
Problem 3 – Pump’s Impeller Rotating in the Reverse Direction
Becoming a cause of severe damage to the pump, the inverse rotation of the impeller is a common problem among centrifugal pumps.
Solution – Make sure you verify which side your motor turns when connecting it to power.
Problem 4 – Pump Becoming Dry
A centrifugal pump can run dry and not allow fluids to pass for several reasons, including part clogging, operating at an inappropriate speed, reversed operation, a very high suction lift, and air trapped inside the pump.
Solution – Firstly, if you notice clogging in your pump, clean the filter, impeller, and valve. Secondly, in case of a reversed operation, see the direction of rotation of the impeller. Furthermore, check the inlets for any impediments if you feel the suction life is at an increased level. Another vital aspect to look for if you want your pump running is to fill it with liquid to the brim and not leave any space for air to get trapped.
Problem 5 – Bearings Getting Overheated
Overheated bearings are alarming because they indicate a fault in the centrifugal pump, which leads to decreased pump efficiency. Overheated bearings may result from a blockage in the following places: open-ended discharge line, valve, suction filter, or recirculation port.
Solution – the first thing you need to do is check if the pump is sufficiently lubricated. If this is not the case, then the lubricating oil might not be of good quality and might cause rusting of the pump. Moreover, look at the center of the motor and the pump; if they are not aligned, this might be the reason for the bearings heating up.
The problems mentioned above are some prevalent issues faced by centrifugal pumps. Now that you know the solutions, you don’t have to worry anymore! However, there are still times when a professional is needed to resolve the more complicated issues and maintain the centrifugal pumps, which is why responsive and trustworthy after-sales service from the provider is important.
