aodd pumps FAQ
An Air-Operated Double-Diaphragm Pump (AODD) can be described as one of the types of positively displacement (PD) pump. It is comprised of two pumping chambers which are filled alternately and then discharged through the movement of diaphragms with flexible diaphragms.
An AODD pump moves fluid by the alternate and repeated back-and-forth movement (strokes) of two flexible membranes or diaphragms mounted on a common shaft. Although diaphragm pumps can be driven directly, with the shaft connected directly to a motor, an AODD pump uses compressed air with a sophisticated distribution system directing the air alternately to two air chambers on the opposite sides of the diaphragms.
Air operated diaphragm pumps can transfer liquids with low, medium or high viscosities, as well as liquids with suspended solids. They also can handle many aggressive chemicals such as acids because they can be constructed with a wide variety body materials and diaphragms.
