ARO PD05P-AAS-PAA Diaphragm Pumps

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. Product Description ARO Compact Double Diaphragm Pumps provide peak performance in a small package. These positive displacement pumps are available in sizes ranging from 1/4" to 3/4" and flow rates up to 14.8 GPM (56 LPM).
