A suction pump is a device that creates a vacuum to draw fluids or gases from one location to another. It works by reducing the pressure inside a chamber, allowing atmospheric pressure to push the liquid or gas into the pump. Suction pumps are commonly used in various applications, including medical procedures, industrial processes, and aquarium maintenance. These pumps come in different types, such as diaphragm pumps, gear pumps, and centrifugal pumps, each designed for specific tasks. They are essential tools in many fields, helping to move substances efficiently and safely while preventing contamination or spillage.
