The ARO 650717-C is a 1" air-operated double-diaphragm (AODD) pump from ARO's U.L.-listed fuel-transfer line — purpose-built for moving petroleum fuels, self-priming and rated to about 29 GPM on compressed air up to 120 psi.
It pairs an aluminum wetted body with a Viton (FKM) diaphragm and Acetal balls and seats. Viton is the elastomer of choice for gasoline, diesel, kerosene, aviation fuel and fuel oil, and the pump carries a U.L.-79 listing for flammable-fuel service. To meet U.L.-79 a built-in pressure-relief valve bleeds off excess pressure, and it can be plumbed to return that fuel to the supply container. Bolted construction keeps the fluid path leak-tight.
It is built for high-volume fuel transfer, bulk unloading, vehicle refueling and equipment servicing. Not sure this build suits your fuel or setup? Send us your application details and we'll point you to the right part number.
