500 Gallon Vertical Tank Package (500Rv-R23D)

UL 142 is the Underwriters Laboratories standard for aboveground steel storage tanks used to hold flammable and combustible liquids. A UL 142 listing confirms the tank meets recognized safety and construction requirements, which is often required by fire codes and insurance policies for facilities storing oil or other combustible fluids.

This package is specifically configured for oil — it includes an ARO 'Thunder' oil pump and a 1/2" x 50' oil reel, indicating it is intended for storing and dispensing lubricating oils rather than fuels or water-based fluids.

A 3:1 pump ratio means the pump delivers three times the fluid output pressure relative to the incoming air supply pressure — for example, 30 PSI of compressed air yields approximately 90 PSI of fluid pressure at the outlet, allowing the pump to move viscous oils efficiently without requiring a high-pressure air source.

The package is comprehensive — it includes the 500-gallon tank, ARO 'Thunder' 3:1 oil pump, 1/2" x 50' oil reel, digital meter, air filter/regulator with gauge, 5' air hose, tank gauge, and fill cap. The primary item you need to supply is a compressed air source to power the pneumatic pump.

The included air filter/regulator with gauge conditions the compressed air before it reaches the pump, removing moisture and particulates that could damage the pump internals while allowing you to dial in and monitor the air pressure for consistent, controlled oil dispensing.

The digital meter tracks the volume of oil dispensed from the tank, enabling accurate charge-back to jobs or vehicles, inventory management, and early detection of any unexpected usage that could indicate leaks or waste.
