A pump is a device used to move liquids or gases from one place to another by increasing pressure. Think of it as a mechanical heart, pushing fluids through a system. It can be as simple as a hand-operated bicycle pump or as complex as an industrial water pump. Unlike gravity-fed systems, a pump actively forces the fluid to move. It is vital in many applications, from supplying water to homes to circulating coolant in engines. It is like a helpful assistant moving essential items around.
