A pump mechanism is a device designed to move fluids, such as liquids or gases, from one place to another. It operates by creating a pressure difference, which allows the fluid to flow through pipes or hoses. Common types of pumps include centrifugal pumps, which use rotational energy, and positive displacement pumps, which move fluid by trapping a fixed amount and forcing it into the discharge pipe. Pumps are widely used in various applications, including water supply systems, heating and cooling systems, and industrial processes. They play a crucial role in ensuring efficient fluid movement, making them essential in both residential and commercial settings.
