ARO Fuel Pumps are specifically designed for high volume fuel transfer, bulk unloading, or re-fueling. These high quality diaphragm pumps meet UL79 specification code. They are compatible with unleaded fuel, diesel, keorsene, aviation fuel and fuel oil.
Note: To meet UL79 specifications, pumps utilize pressure relief valves to limit dispensing line pressure to under 50 PSI. If line pressure exceeds 50 PSI due to thermal expansion, compression, backfeed, or gravity; the pressure valve opens and bleeds off excess pressure. The relief valve must be plumbed to return the bled off fuel to the storage container.
