Why should one use centrifugal pumps

Integrally geared centrifugal pumps are preferred in India now-a-days. These centrifugal pumps are fairly simple. They use kinetic energy to move the liquids. The low flow pumps in India has an engine attached to the axis similar to that of ship’s water wheel.

While most of the integrally geared centrifugal pumps are used for water, some of these low flow pumps in India are also used for sewage and chemicals.  Because of the direct conversion of the energy, this is a very simple pump. As with all the pumps, there are advantages and disadvantages for these pumps too.

Advantages of Integrally geared centrifugal pumps

  • The biggest advantage is that they require no values or any moving parts. It also allows high flow at a very low maintenance. The output is also very steady.
  • As there is no drive seals or values, there is no leakage in the pump.
  • There is almost zero noise and has minimum wear.
  • Centrifugal pumps eliminates the risk of motor damage.
  • It can be used to pump hazardous liquids and chemicals.
  • Easy to clean or remove and acquires less space.

Disadvantages of Integrally geared centrifugal pumps
  • Rotation is used of  suction .
  • There is some kind of energy loss involved.
  • These integrally geared centrifugal pumps can develop cavitation, which causes bubbles. These bubbles can be corrosive in nature and can lead to significant pump damage. It can be caused due to improper use of pumps.

For most household or light industrial uses, a centrifugal pump is fine.  As long as the liquids aren’t too viscous, like mud or waste, and the pump can be totally submerged They are ideal for any kind of liquid transfer., it will provide consistent, effective, and reliable operation.
