The ARO U.L. listed pump for pumping petroleum products,
offers high volume delivery at low air pressures and easy
self-priming. This model is designed specifically for the trans-
fer, bulk un-loading or fueling applications. It includes a pres-
sure relief valve (per U.L. Specification 79) which restricts the
fluid outlet pressure to under 50 psi (3.4 bar), The relief valve
can be plumbed to return the bleed off fuel to the storage
