What is the function of a pump in a fluid system?

A pump in a fluid system serves to move fluids from one location to another, overcoming resistance and pressure variations within the system. It converts mechanical energy into hydraulic energy, enabling the flow of liquids or gases through pipes, valves, and other components. Pumps are essential for maintaining desired flow rates, pressures, and ensuring the efficient operation of various applications, such as water supply, heating, and industrial processes.
