A simple look at how the AODD works.

A positive displacement (PD) pumping system with an air-operated double-diaphragm (AODD) is comprised of two siphoning chambers that are on the other hand filled and removed utilizing flexible diaphragms. To give the siphoning movement, compacted air is taken and set free from air chambers on inverse sides of the diaphragm. AODD siphons are regularly utilized in moving applications and can deal with a wide scope of feeds, including slurries, rough, and shear touchy liquids. They are strong, trustworthy, and easy to work with, even though they can be uproarious, inclined to icing, and restricted to low-pressure applications.

The liquid is moved by the to and fro development (strokes) of two adaptable films or diaphragms organized on a common shaft in an AODD siphon. Although diaphragm siphons can be operated straight by associating the shaft to an engine, an AODD siphon utilizes compacted air that is sent then again to two air chambers on rival sides of the diaphragms.
