Abstract:
A delivery unit for a liquid additive includes a first pump with a first suction port and a first pressure port, a second pump with a second suction port and a second pressure port, and a feed device. The feed device is connected to the first pressure port through a first line system and the first suction port is connected to a tank for the liquid additive through a second line system. The second pressure port is connected to the tank through a third line system and the second line system and the third line system are separated from one another. A method for operating a delivery unit and a motor vehicle having a delivery unit are also provided.
