These are still vulnerable to damages that require immediate repair despite the fact that these were made to be durable heavy equipment. Here are some of the common issues you might come across and the appropriate measures to take to fix it.
Leaks should not be a reason for worry. A pump usually has this problem. If you want to determine the precise location of the leak, you need to take a close look at it. Doing so will allow you to tell the repairman where the problem is and he will be able give you an estimate of the total cost for the repairs. As soon as you start hearing unusual sounds, it is very probable that a foreign object might be jammed inside. Too much pressure and water can also cause a lot of noise. Other sources could be cavitations and bearing failure.
Vibrations are brought on by problems in the system. Then again, the pump itself can be a reason. Look at the pipes and separators in case these are causing the vibration. A great deal of seal water and constant carryover can also be an underlying cause. If there is tension and a problem with the alignment of the coupling or V-belt, these could be the reasons behind the unusual vibrations.
If the pumps cannot easily start, you need to take a look at the power supply and guarantee that it is connected correctly. If there are no problems with the connection, then the cause for such failure could be a malfunction in the electrical system. Over flooding of oil and extremely low temperatures can also be the contributors. Once you know where the problem is and what caused it, you can contact the repairman and have it fixed as soon as possible.
