A mechanical pump is a device used to move fluids or gases from one place to another. It operates by converting mechanical energy into hydraulic energy, allowing it to create flow and pressure. Common types of mechanical pumps include centrifugal pumps and positive displacement pumps, each designed for specific applications in industries like water treatment and oil and gas. These pumps can be powered by various sources, including electric motors, engines, or manual operation. Mechanical pumps are essential in many systems, such as heating and cooling systems, irrigation, and chemical processing, ensuring efficient fluid movement and management.
