Types of Pumps

There are various types of pumps used in industrial applications, each designed for specific purposes. Centrifugal pumps are one of the most common types of pumps utilized in industries such as oil and gas, water treatment, and chemical processing. These pumps use the centrifugal force generated by a spinning impeller to impart kinetic energy to the liquid, causing it to move through the pump and into the piping system.

Centrifugal Pump vs Fan

While both centrifugal pumps and fans operate based on the principles of centrifugal force, they serve different functions. Centrifugal pumps are primarily used to move liquids, while fans are designed to move gases. The impeller design and operational characteristics of centrifugal pumps and fans vary to accommodate these distinct applications.
