[origin: EP2772650A2] The vacuum pump has a pump inlet (10), a pump outlet (14) and a pump chamber (18) for a gas to be pumped, where the pump housing is arranged between the pump inlet and the pump outlet. A cooling gas inlet (48) is provided for a cooling gas for cooling the vacuum pump. One or more hollow portions are provided for the cooling gas and are arranged outside the pump chamber. Each hollow portion is limited by a component of the vacuum pump. One of the hollow portions is connected with the pump outlet in a conductive manner. An independent claim is included for a method for operating a vacuum pump.
