Why is your submersible pump failing?

In the world of pumping, you will often come across many manufacturers providing you a variety of pumps like submersible sewage pumps, dewatering pumps, etc. However, while telling you about themselves and their products, they hardly ever mention the possible cause of failure of their pumps.

In this blog, we are going to choose the path of honesty, and tell you all about the reasons of a submersible pump’s failure. Even though we are the proud manufacturers of many submersible pumps like submersible sewage pumps etc., we understand that this is something our customers should know.

Following is a list of reasons to a submersible pump’s failure:

1. Ignorance and wrong selection of the submersible pumps

Although this reason might sound tiny, but it is the most common reason for submersible pump failure.  Many a times customers have an ignorance towards pumps & are often ill advised in this regard. Eventually they end up buying wrong pumps. This may not only lead to wrong use of pump, but often affect the performance of the submersible pumps, eventually leading to its failure. 

Not only this, but many times people try to use a one pump for several different needs & without knowing it make pump useless all purposes. 

2. Dry running of the pump

This is 2nd most common reason for submersible pump failure. After selecting a right pump, it is also important to ensure that it is put to use for right purpose & is also equipped with basic control precautions. Taking these things for granted eventually leads to dry running of submersible pumps. What people don’t know is that the dry running of a submersible leads to heating up the motor of the pump. This causes it to fail.

3. Reverse rotation 

This failure is caused when a submersible pump is wired incorrectly. This means that the motor would run backwards. In case this happens, a very less amount of water gets pumped. Moreover, this seriously damages the pump. It also polishes the impeller which further leads to cavitation.

4. Cable Damage

This is another common reason for submersible pump failure. More often than not, cable is most ignored part of the pump. Mishandling of pump can cause internal or external damage to cable. If the cable has been yanked or gashed, then it should immediately be checked. One should always ensure that there is no undue stress on cable during it handling or fitment. The seal arrangement where the cable is entering the pump’s body, is a weak spot, even just a few drops of moisture can successfully lead to the pump’s failure.

Apart from these, there can be other reasons (which we will cover some other time) leading to a submersible pump’s failure.

However, keeping these above most common points in mind will help you make better decisions regarding pump selection & its usage. Contact Darling Pumps at +91 9981992833, or visit www.darlingpumps.in
