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

Questions about water pumps? Get your answers here!

Whether you’re thinking about dewatering pumps, submersible waste water pumps, sewage pumps, or any other type of water pump, it’s natural that you would have many questions popping in your head, Well, if anything, that’s a good thing. However, it’s only healthy to get the answers to all these questions before the lack of knowledge gets you in trouble.

In an attempt to help you and many others like you, here’s a tiny list of those questions along with their answers: 

1.What do you mean by an open centrifugal pump?

These pumps use centrifugal force for pressurizing and moving water from inlet to outlet. The pump shaft spins the impellers. Water gets forced through the impeller and rotational energy gets transferred from the impeller to the water. 

2. Why is my pump making noises?

Mostly water pumps are fairly quiet while in operation, However, at times pumps may make noise due lose & faulty installations, improper pipe fittings or noise may even come from hydraulic portion of pump. Therefore, always ensure weather the noise is coming from the pump. If the pump makes a popping, growling, squealing, or grinding noise, then you should immediately get it attended by trained service technician who may have to disassemble it and inspect for damage. 

3. Why did my pump’s shaft break?

The shaft failures could be because of many factors. These include:

• Sudden & frequent starting or stopping the pump.
• When engaged suddenly, a water pump may twist the impeller off the shaft. This can end up damaging the shaft & bearings.
• Water hammer that is caused by a sudden shut off of water flow causes the impeller to break the pump shaft. Over time, it also damages the shaft bearings. It always advisable to have NRV fitted to pipeline.
• A damaged or unbalanced impeller may cause shaft failure as well as bearing damage.

4. When should the gaskets of the water pumps be replaced?

Whenever the water pump is partially or fully opened for servicing or for any other reason. Also if Gaskets are found to be damaged or cut they should be replaced. They are inexpensive, and a faulty gasket causes the water pump to leak.

What questions should be answered, before selecting sewage pumps?

When it comes to sewage pumps, everyone’s dream and necessity is to own a properly working one. This stands true especially for homeowners who have basement toilets. 

The role of sewage pumps is to lift flushable waste into a septic tank or the sewer line. There are many people who often go for replacing their water pump with the same model as before. Before making the decision, you should always ask yourself, how long should your pump last?

Similarly, when selecting the right sewage pumps for your needs, there are some questions that you should ask yourself! The following is a list of those questions, along with the answers to the same:

1. How much flow is required?

To know what type of flow rate is required, it’s important to know the number of users that would be feeding the sewage basin as well as the number of drains. If you want to know a great rule of thumb, then its 50 gallons per person per day for residential use.

2. What about the vertical lift’s distance?

If you are familiar with the pumping industry, then you would have questions like “what is the total dynamic head?”  and “what is the head?” or something in these lines. All of these questions are asked to help in determining the amount of force or pressure needed for “pushing” the liquid up to where it’s required to go. Considering whether the system lifts to a septic tank, in the absence of any back pressure or to a sewer system with pressure pushing back, is imperative.

3. What are the requirements when it comes to solids handling?

Such type of requirements might be easily determined by the local codes. A sewage pump should have the capacity to handle spherical solids that are up to 2” in diameter, unless otherwise stated.

4. What is the size of the pump basin required?

Normally, the flow rate determines the size of the basin that is needed. A properly sized basin allows the water pump to run for longer on each cycle. It would also help to cycle less times each day. Generally, the larger the motor, the less cycles each day are recommended and the longer becomes the run time that is needed. Usually, the owner’s manual indicates the max number of cycles in a period of 24 hours. Taking this into account, with the flow rate, would help in determining what would be right for you. With higher flow rates, the basin’s diameter needed increases. 

Therefore, if you’re looking for the right sewage pump for your system, then make sure to answer these questions beforehand.
