A pump is a mechanical device used to move fluids, such as liquids or gases, from one place to another. It works by creating a pressure difference, which allows the fluid to flow through pipes or hoses. Pumps are commonly used in various applications, including water supply systems, heating and cooling systems, and industrial processes. There are different types of pumps, including centrifugal pumps, which use rotational energy to move fluid, and positive displacement pumps, which move fluid by trapping a fixed amount and forcing it into the discharge pipe. Pumps are essential in many industries, including agriculture, construction, and manufacturing.
