How Does An Air Operated Double Diaphragm Pump Work?
An air operated diaphragm 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 then fills the opposite chamber via the inlet manifold. The rapid changeover allows for reduced pulsation at the outlet.
How to Select an Air Operated Double Diaphragm Pump?
Choices are endless when selecting the correct air operated double diaphragm pump (AODD). Aluminum? Stainless? Why Plastic? Different chemicals require different pump components which are critical in determining the best pump solution for the application. Not all applications are the same and neither are the pumps. Check out some general information regarding the construction of Graco AODD Pumps.
