The rugged construction and extra-thick pump casing of Gorman-Rupp Air Driven Diaphragm pumps stand up to the abuses of the most demanding sludge and slurry applications. They overcome the "high wear" problem commonly found in double diaphragm and progressive cavity pumps. They are capable of operating dry, on suction lifts up to 20 feet, and handling high solids content up to approximately 70%.

Air Driven Diaphragm pumps have only three moving parts so maintenance and service are minimal. Replacement of pump diaphragm can be accomplished in about one hour without disconnecting piping. Check valves can also be quickly and easily cleaned out using "twist lok" handles. No special tools required.
