What is the primary purpose of a pump in mechanical systems?

The primary purpose of a pump in mechanical systems is to transport fluids from one location to another. Pumps are designed to move liquids or slurries, using mechanical action to create a flow or pressure differential that allows the fluid to be conveyed through pipelines, hoses, or other delivery systems. This movement is essential in various applications, such as transferring water in irrigation, circulating coolant in machines, and delivering fuel in engines.

While there are other devices or systems that perform tasks like compressing gases, generating electrical power, or cooling machinery parts, these functions are not the core responsibility of a pump. A pump's main role is specifically focused on fluid transport, making it a vital component in many industrial, agricultural, and domestic applications.
