Latham - Air Operated Diaphragm Pump (AODD)

An Air Operated Diaphragm Pump (AODD) is a type of positive displacement pump. The pump has two pumping chambers that are alternately filled and discharged by the movement of flexible diaphragms. The pump used compressed air is alternately fed to, and vented from, air chambers on the opposite sides of the diaphragms to create the pumping action. They are reliable, easy to maintain and very durable however they limited to low pressure, they can be noisy, and they can be prone to freezing if weather conditions drop below certain temperatures.
