How Centrifugal Pumps Have Become Important for Heavy Industries

The pumps that are most commonly used in industries are centrifugal pump which is used to move water or other fluid with the help of impeller, where conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow takes place. Heavy industries are showing an emerging trend and require these centrifugal pumps to achieve the core work of industry. Why these pumps are used so vigorously in industries, some of the common uses include water, sewage, petroleum and petrochemical pumping. Let us know how these pumps came into existence, according to Reti, the first machine that could be characterized as a centrifugal pump was a mud lifting machine which appeared as early as 1475 in a treatise by the Italian Renaissance engineer Francesco di Giorgio Martini. True centrifugal pumps were not developed until the late 17th century, when Denis Papin built one using straight vanes.

Reason why these pumps are so popular in heavy industries, the usage itself is an answer for this. Some of the applications are listed as following:

1. Textile sector - Bleaching of fabrics and silk
2.  Food  sector- Sugar refining, bleaching, and disinfecting 
3. Water/Chemicals sector - Purifying water, deodorizing sewage, and industrial effluents. 
4. Pulp and Paper sector - Bleaching pulp, fireproofing and wood preserving. 
5.  Agriculture sector - Fertilizer, fungicide, and insecticide manufacturing 
6.  Electronics sector - Chip and metal cleaning, and acid waste transfer 
7.  Steel sector - Steel and Stainless steel picking 
8.  Oil and Gas sector - petroleum purification 
9.  Chemical sector- Catalyst transfer, and neutralizing 
10.  Metal Treating sector - Anodizing, and electroplating

The usefulness of centrifugal pump are just one side of the coin, the other side of the coin is its advantages.

1. There are no drive seals; hence it reduces the risk of leakage. This gives an advantage of pumping hazardous liquids without spillages. 
2.  No heat transfer from the motor— a thermal barrier is provided by an air gap that separates the pump chamber from the motor. 
3.  There is a complete separation of the liquid means that liquid cannot seep into the motor from the pump. 
4.  Reduced friction. 
5.  Magnetic coupling can be broken—if the load of the pump is too great the magnetic breaks, it means the pump does not overload and get damaged.

After going through all this above mentioned points, I think the question how centrifugal pumps have become important for heavy industries has been very well answered.
