Air Operated Double Diaphragm (AODD) pump is a type of positive displacement pump that uses compressed air as the driving force to move a flexible diaphragm back and forth. This diaphragm creates a reciprocating motion that draws in and expels fluid, making it an effective pump for various applications across industries. Here's a detailed description of the key components and operation of an AODD pump:AODD pumps typically have two diaphragms, one on each side of the pump chamber. These diaphragms are made of flexible materials such as rubber, thermoplastics, or elastomers. They are the central components responsible for moving the fluid by flexing in response to changes in air pressure. The pump has two air chambers, one behind each diaphragm. These chambers are separated from the fluid chambers by the diaphragms. When compressed air is introduced into one of the air chambers, it pushes the diaphragm in the opposite direction, creating a vacuum in the fluid chamber. This vacuum causes fluid to be drawn into the pump.
