The Diesel Exhaust Fluid (DEF) pump is a device used to transfer DEF from storage containers to the vehicle's DEF tank. DEF is a non-hazardous solution composed of urea and deionized water that is used in selective catalytic reduction (SCR) systems to reduce harmful emissions from diesel engines. It generates the necessary pressure to transfer DEF. It is often an electric or air-operated diaphragm pump designed specifically for DEF handling.

Attributes:
• Designed and constructed to handle Diesel Exhaust Fluid.
• Built with adequate pressure rating
• durable and reliable.

Applications:
The Diesel Exhaust Fluid pump is extensively used in the automotive and trucking industry. Commercial vehicles such as trucks, buses, and delivery vans equipped with SCR systems rely on DEF for reducing nitrogen oxide emissions. DEF pumps are utilized at fuel stations, truck stops, and maintenance facilities to refill DEF tanks in these vehicles.
