摘要:
The invention relates to a pump assembly comprising a pump unit and an electric motor driving said pump unit and comprising a rotor (1) having a rotor shaft (2, 3) and a rotor stack (3) fastened thereon. The fastening of the rotor stack (3) on the rotor shaft (2, 3) is performed by means of a circular key joint (5, 6) comprising at least one circular key (5) on the side of the rotor shaft (2, 3) and a complementary circular key (6) on the side of the rotor stack (3).
