A urea dispenser transfers DEF from a dedicated storage tank to the vehicle’s urea tank using a corrosion-resistant pump and sealed delivery system. The process begins when the user activates the dispenser, allowing fluid to flow through a filtered hose and nozzle.
The dispenser’s flow meter measures the exact volume dispensed, while electronic controls regulate speed and prevent overflow. Automatic shutoff nozzles stop dispensing once the tank reaches capacity, minimizing spills and waste.
This controlled operation ensures accuracy, cleanliness, and safety. It also protects the vehicle’s SCR system from contamination, which is critical for maintaining emission performance and avoiding costly repairs.
