A centrifugal pump is an important part of any commercial establishment. Its function is to move any low viscosity liquid like water, and it works on the principle of converting electricity into kinetic energy.

If you are planning to buy a centrifugal pump, here are the six things that you must consider before you make your purchase.

1. Where Are You Planning to Install It?

A centrifugal pump is used to move large amounts of liquid at a fast pace and might not be a great fit for individual residences. On the other hand, they are the perfect choice for commercial establishments such as water treatment plants, food processing units, and manufacturing plants as well as hotels and buildings.

You can also use a centrifugal pump to irrigate your farmlands during the dry months.

2. Flow Rate

Whether it is a borewell pump or a centrifugal pump, the flow rate determines its general effectiveness. Flow rate is the time taken by a pump to pump out a specific volume of liquid and is measured in litres per minute.

For commercial use, your centrifugal pump should pump more than 2500 litres of water per minute. When it comes to domestic use, your centrifugal high-pressure pump can have a flow rate between 100-200 litres per minute.

3. Inlet Size

In a centrifugal pump, the water enters through the inlet pipe into the impeller’s eye where the fluid rotates at a very high speed. As a result of this, a vacuum is created at the eye of the impeller, and the liquid is discharged through the outlet. The vacuum is also instrumental in ensuring that more water is drawn into the pump.

The size of the inlet pipe, therefore, determines the amount of liquid that comes inside the pump. The more the size of the inlet, the more amount of water is pumped inside and therefore, pumped out faster!

A typical centrifugal pump would have an inlet in the size range of 1 to 6 inches, but it can also be bigger in size.

4. Maximum Head Pressure

The maximum head pressure of a centrifugal pump is extremely important. It indicates the highest point where the device is able to pump water.

For example, if the maximum head pressure of a solar water pump is 60 metres, you can pump water only up to this height. Beyond this, the flow rate of the pump will be zero, and no water will reach higher levels.

You should especially take this into consideration when you use a centrifugal pump in a high-rise building. It would be best if you always chose a centrifugal pump that has the maximum head pressure higher than the height that you intend to pump the water.

5. The Quality Of The Pump

Buying a centrifugal pump is not a small matter. It is the foundation of your plumbing system, and therefore, you must take into consideration the quality of the device that you are installing in your property.

From the material of its body to the engine or motor, they severely impact the experience that you have with the pump. The best way to ensure that you are choosing the right pump for your requirement is to do your research and understand how the different elements measure up against your requirement.

6. Type Of Water To Be Pumped

Depending on whether you are pumping water in a commercial building or agricultural land, there is a significant difference in the type of pump that would serve your purpose.

The decision to purchase a centrifugal pump should be made only after thorough research into the kind of water you’re pumping, which would enable you to list the requirements side-by-side with the features that those requirements would need.

Choosing any major home device is not an easy task, but when it comes to choosing a pump that would form the basis of your plumbing system, you have to have a comprehensive idea of what will work for you.

When you choose a centrifugal pump for your needs, make sure that you consider these six simple criteria before you zero-in on your purchase and Crompton provides the best range of pumps that will suit any of your needs.
