Abstract

A sealing element for sealing a high-pressure side from a low-pressure side at a rotating shaft, in particular in a pump, with a supporting ring configured to be arranged on a stator surrounding the shaft and from which a first annular membrane protrudes facing in the direction toward the shaft. From the first annular membrane, a second annular membrane protrudes facing in the direction toward the shaft. The first annular membrane is formed longer than the second annular membrane as viewed in the axial direction of the shaft, and the second annular membrane is configured with a sealing edge which is to be arranged lying on the shaft.
