How does an air operated double diaphragm pump work?
An air operated diaphragm pump (also known as a membrane pump) is a type of positive displacement pump that uses compressed air as a power source. The compressed air is shifted from one chamber to the other by a linked shaft that allows the chambers to move simultaneously. This back-and-forth motion, forces liquid out of one chamber and into the outlet manifold, while filling the opposite fluid chamber via the inlet manifold. Upon changeover, the fluid section that was filled on the previous shift empties into the outlet manifold and the fills the opposite chamber via the inlet manifold. The rapid changeover allows for reduced pulsation at the outlet.
