Inside the sealing shroud of the centrifugal pump there is located an inner rotor driven by a drive motor, while an outer rotor which is connected to the pump impeller is located outside of the sealing shroud wall. At least the sealing shroud wall is formed of a material which is electrically non-conductive. The efficiency is improved. Materials not normally used in sealing shrouds, such as ceramics, can be used for the same and this increases the usefulness or fields of application of the pump. |
