Abstract (en)
[origin: WO2016071443A1] A pump unit for reducing agents in an exhaust gas purification system for an internal combustion engine of a motor vehicle comprises a pump stage (18) that includes a reinforcement ring (28, 29) in a membrane (20). The reinforcement ring (28, 29) is pressed into housing parts (21-23) of the pump stage (18), thereby rendering the sealing tightness of the pump stage (18) highly reliable.
