The invention relates to a vacuum pumping system having an oil-lubricated vacuum pump. The vacuum pumping system (100) comprises an oil-lubricated vacuum pump (20), comprising a stationary pump statorand a rotatable pump rotor (23), and a motor (30), comprising a stationary motor stator (32) and a rotatable motor rotor (33) cooperating with each other for driving in rotation the pump rotor (23).The motor (30) further comprises an oil-tight unit (50) consisting of a metal jacket enclosing the motor rotor (33) and forming a container intended to collect and keep inside the motor (30) any oil leaking from the pump (20). 本发明涉及具有油润滑真空泵的真空泵系统，所述真空泵送系统(100)包含油润滑的真空泵(20)和马达(30)，所述油润滑的真空泵(20)包含固定的泵定子和可旋转的泵转子(23)，所述马达(30)包含固定的马达定子(32)和可旋转的马达转子(33)，所述固定的马达定子(32)和可旋转的马达转子(33)相互配合用于驱动所述泵转子(23)旋转。马达(30)还包含不透油的单元(50)，该单元由金属护套组成，该金属护套包围所述马达转子(33)并形成容器，所述容器用于收集从泵(20)泄漏的任何油并将其保持在马达(30)内部。
