Also referred to as an air operated diaphragm pump (AODD), pneumatic diaphragm pump, and a membrane pump, a diaphragm pump is a positive displacement pump using a reciprocating motion of a rubber-like diaphragm to suction substance from the entrance valve into a chamber when expanding and upon compression pushes the substance through the exiting valve.

One of the main benefits of air-operated diaphragm pumps is there’s no need for lubrication.

Engineered for maximum fluid and chemical compatibility, the All-Flo 3-in. aluminum dual-diaphragm pump is a heavy-duty solution. The stall-free and non-metallic air section makes sure operation doesn’t freeze or stall.
