Pumps are mechanical devices designed to move fluids, such as liquids or gases, from one location to another. They play an important role in various industrial applications, including water supply, wastewater treatment, oil and gas, chemical processing, and more. They have various categories based on their operating principles, such as centrifugal pumps, positive displacement pumps, or axial flow pumps.
