Air Driven Diaphragm Pumps

Gorman-Rupp air driven diaphragm pumps stand up to the abuses of the most demanding sludge and slurry applications due to the rugged construction and extra thick pump casing.

Air-driven diaphragm pumps can operate dry, with the suctions lifts up to 20ft. and can also handle high solid contents up to 70%.

Compressed air applied to top of diaphragm forces the diaphragm down and discharges liquid.

The solenoid is then signaled by an adjustable controller to halt incoming air. Compressed air is then directed into the bottom of air cylinder, raising the air cylinder piston and retracting the diaphragm. The retracting diaphragm fills pump cavity for next stroke.  Used air is exhausted to the atmosphere.
