UL 79 Spec AODD Pumps

Designed specifically for high-volume transfer, bulk unloading or fuelling applications. The pumps meet UL 79 specification code and are compatible with gasoline, aviation fuel, diesel fuel, fuel oil, and kerosene.

To meet UL 79 specifications, pumps utilise pressure relief valves to limit dispensing line pressure to under 50psi.

If line pressure between the pump and the dispensing point exceeds 50psi due to thermal expansion, line compression, backfeed, or gravity, the pressure relief valve opens and bleeds off the excess pressure. The relief valve must be plumbed to return the bleed-off fuel to the storage container.
