Why can slip rings suppress noise? The sealing device of the slip ring is preferably applied to the water pump to suppress noise. The vibration-damping component, especially its elastic component, is designed so that it can generate a kind of micro-friction, which can lead to the best suppression of noise. The problem when using the slip ring sealing device is that it will generate noise under certain conditions of use. There are currently no effective measures to adequately dampen the vibration of the slip ring seal and avoid noise. This type of slip ring seal is designed so that it can be manufactured cost-effectively, and it guarantees effective noise containment. The vibration-damping component has a shaped metal plate which can be produced simply and cost-effectively. Because of its shape stability, it can be simply installed on the slip ring sealing device, and the metal plate ensures a long service life of the vibration-damping component.

The reducing part is supported by the elastic part under the prestress. Based on the metallic structure of the vibration-damping component, it can be adjusted to the required prestress in order to obtain the vibration-damping effect that is optimally adapted to the application of the slip ring sealing device. There is a slight friction between the vibration-damping component and the support area, which leads to a vibration-damping effect. Even under the most extreme operating conditions, this vibration-damping component can effectively suppress noise. It can be manufactured cost-effectively and easy to install, while ensuring a long service life. Such a slip ring sealing device can be advantageously used in automotive technology.

The vibration-damping part has an outer shell which is supported on the wall portion of the mounting cavity of the slip ring seal device under radial prestress. Advantageously, the elastic member is provided with a contoured contour on its circumference, in particular a contoured contour. This shaped profile ensures on the one hand the best vibration damping and on the other hand a high stability of the damping components.
