Pneumatic pumps are devices that use compressed air to move fluids. They operate by creating a vacuum that draws liquid into a chamber, which is then expelled through a discharge outlet. These pumps are commonly used in various industries, including manufacturing, construction, and food processing, due to their efficiency and ability to handle different types of fluids. One of the key advantages of pneumatic pumps is their ability to operate in hazardous environments where electrical equipment may pose a risk. They are also relatively easy to maintain and can be used for both low and high-pressure applications, making them versatile tools in fluid management systems.
