These air-operated double-diaphragm (AODD) pumps are versatile and can pump virtually any liquid safely and effectively. These models deliver flow rates up to 160 gallons per minute (GPM) in a wide range of body materials, making them suitable for transferring anything from water to acids. Capable of running dry, these pumps are designed to handle solids efficiently. They can be dead-headed without a bypass for on-demand applications. Since they are operated by compressed air, no electrical connections are necessary. Groundable units are available, offering a variety of safety certifications such as ATEX. Every unit integrates longevity and ease of maintenance with the innovative patented air valve and diaphragm technologies.
