When distributors are transporting Diesel Exhaust Fluid (DEF) to fleets there are two major considerations:
This means that the bulk DEF tankers must meet the specifications required to prevent contamination of the fluid and limit corrosion. The tankers are equipped with an insulated tank and cabinet. The cabinet and piping system is sometimes heated too, ensuring the DEF remains between 14°F (-10°C) and 86°F (30°C).
Portable DEF bulk transfer pump systems are also required for delivery to customer tanks. A transfer pump is designed to connect the bulk tank to the tanker and transfer the DEF at a flow rate of up to 25 gallons per minute (GPM). For ease many tankers have been designed to self-load from a large DEF bulk storage facility.
Distributors use DEF bulk transfer skids to refill drums and totes, these normally have flow rates of 25-250 GPM.
