  • What is a double diaphragm pump?

    The ARO range of air operated diaphragm pumps offers many materials of construction. 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.
