A DEF pump system is a device that is used to transfer diesel exhaust fluid (DEF) from a storage container to a vehicle's onboard DEF tank. DEF is a liquid that is used in diesel engines to reduce harmful NOx emissions.
DEF pump systems typically consist of the following components:
- A pump: The pump is responsible for moving the DEF from the storage container to the vehicle's onboard tank.
- A filter: The filter removes any impurities from the DEF before it is pumped into the vehicle's tank.
- A controller: The controller regulates the flow of DEF from the pump to the vehicle's tank.
- A nozzle: The nozzle is used to dispense the DEF into the vehicle's tank.
