Abstract (en)
[origin: EP2772651A2] The vacuum pump (10) has a side-channel pump stage (12) which has a side channel with a stator element (14), where a coolant circuit (25) is formed for cooling the vacuum pump with a coolant. The coolant circuit has a coolant channel (18) for the side-channel pump stage. The coolant channel is bounded by the stator element. The coolant circuit is formed for cooling a component of the vacuum pump. The component is selected from the group of a drive electronic (20), a motor (22), a high vacuum pump stage (24), a housing and a bearing plate of the vacuum pump.
