5 Indications Your Centrifugal Pump Needs Repair

Centrifugal pumps are quality components in most industrial activities. At times, production efficiency depends on how well your centrifugal pumps are functioning. Frequent servicing and checkups are ideal for good functioning. However, centrifugal pumps can indicate when they have broken down or are not in good use. It is good to take quick action in cases where the pump starts showing the need for repairs. Fixing the pump reduces the risk of total breakdown during the work process and of the pump having damages beyond repair. Therefore, find the right industrial equipment stores to find the right parts for your repair needs. Below are indications that your centrifugal pump requires attention for repairs.

    Leakage of the pump

The first red flag to a pump that is breaking down is leakage. High temperatures, excessive pressure, or even corrosion of the pump loosens its joints and seals. Loose seals and joints allow fluid flow out of the pump, therefore, escaping. It is simple to fix a leakage in the pump than buying the entire pump. Fixing pump leakages is as easy as tightening the fasteners that are around the pump. However, in different cases, the gasket or mechanical seal may be needing some little replacing. To take good care of your pump, avoid dry running of the pump since it will lead to blisters or heat cracks.

  1. Unusual vibrations or noises

Unusual vibrations or noises

Continuous noises or unusual vibrations are indications of a present problem. Usual causes of the vibrations include the presence of a foreign object in the pump or bearing failure taking place. The vibration of the equipment in accompaniment with rattling noises is a clear sign of cavitation. Cavitation leads to notable destruction to the pump, forcing you to sort out the problem quickly. Pump vibrations are due to pump bearing issues because of poor selection of the pump bearing during its purchasing. You can opt to reduce the pump vibrations by placing it on a wooden floor, an anti-vibration pad, or a noise-reducing pad. These soak all the unusual vibrations from the centrifugal pump.

  1. Overheating


Clogging of pumps always results in overheating of the equipment. In addition, it may cause a reduction in liquid flow. In case a centrifugal pump is overheating, this means that the flow of the liquid in the pump could be under restriction. There are trouble places in the centrifugal pump, for instance, clogging of the recirculation port, obstruction of the air release valve, or line that leads to overheating. It is good to be vigilant and to avoid overheating the pump. Aside from causing harm to the internal components, it can cause severe injuries and burns on anyone dealing with the equipment. Leaving the discharge line open or the suction during operations helps to avoid overheating of the machine.

  1. Low pump flow

Low pump flow

Reduction in pump flow takes the pump into harmful cavitation conditions. It also makes your pump take longer than the expected time during work progress. To be aware of the pump flow decreasing, measure the suction vacuum and the discharge pressure as the pump is operating. The most common causes of flow reduction in the pump are leaking gasket, an open bypass valve, clogging on the suction line, and much more. If you notice any of the above issues or any other unusual issue, contact a pump mechanic so that he can get your pump back in working order. The good thing about low pump flow is that it causes less mixing of formation water with the stagnant casing water.

  1. Slow re-priming

Slow re-priming

The most common cause of slow re-prime is improper clearance. Apart from improper gapping, there are other causes of re-priming. Clogging and lose seals slow down re-priming processes. In cases where the spacing checks out, get a topmost vacuum check at the end to know the exact place of the problem. Carry out priming when you need your pump to function well. According to centrifugal pumps, priming is filling the pumps with water. It is good to note that re-priming is in different ways according to the type of pumps. Therefore, consult a pump specialist to assist you in determining the best way to prime your pump. Note that some pumps can carry out self-priming.
