A suction pump is a device that creates a vacuum to draw fluids or gases from one location to another. It operates by reducing pressure inside a chamber, allowing atmospheric pressure to push the fluid into the pump. Suction pumps are commonly used in various applications, including medical procedures, industrial processes, and water removal. These pumps can be powered by electricity, engines, or manual operation, depending on their design and intended use. They come in different types, such as diaphragm pumps, gear pumps, and centrifugal pumps, each suited for specific tasks and fluid types.
