Air Operated Diaphragm Pump Guide

AODD pumps are a type of reciprocating positive displacement pump driven by compressed air rather than an electric motor. This pump design is made up of two chambers, each with their own inlet check valve, outlet check valve, and diaphragm; hence, they are also referred to as double diaphragm pumps. Due to their design benefits, AODD pumps are a popular pumping solution for many applications, including food, cosmetics, chemical transfer and fuel.
