ARO PF20A-AAP-SAA-B Double Diaphragm Pump

What is a double diaphragm pump? A double diaphragm pump is a positive displacement pump that uses a two sets of flexible membranes to pump fluids and a series of check valves to ensure fluid can only travel in one direction through the chamber. Pump cycling will begin as air pressure is applied. Air operated diaphragm pumps utilize a pressure differential in the air chambers to alternately create suction in the fluid chambers.
