Automatic Double Diaphragm Pumping System

QED has been successfully installing double diaphragm pumping systems on sites all over the world for well over two decades. The system is designed to handle harsh liquids such as leachate, solvents, and fuels. Flow rates range from 0-20 gpm, with options for models with higher rates. The system is pneumatically operated, making it intrinsically safer than electrical systems that can shock, spark, or ignite. These easy-to-use systems are designed for pumping liquids out of sumps, tanks, ponds, and shallow wells, and are available on an open frame, or mounted inside a protective enclosure.
