ARO Diaphragm Pumps by Ingersoll Rand provide stall free and ice free operation while pumping at some of the highest flow rates in the industry. U.L. 79 listed models are specifically designed to ensure that you are in compliance with the standard for power operated pumps for petroleum dispensing products. ARO Diaphragm pumps are ideal for high volume fuel transfer, re-fueling, or unloading. An integrated pressure relief valve ensures that fluid pressure never exceeds 50 PSI. Bled off fuel is then returned to the storage container. The exteriors of these high quality pumps are made from aluminum while the wetted components are molded from chemically resistant Viton.
