Abstract
A shaft sealing arrangement for a pump for delivering hot fluids includes a dynamic shaft seal (), in particular a slide ring seal, in order to seal a rotatable shaft () relative to a housing (), and a cooling ring () which is mounted in front of the dynamic shaft seal () in the direction of the pump interior and which surrounds the shaft () at a small spacing. The shaft sealing arrangement further includes an additional seal () which seals the shaft () in the region of the cooling ring () in order to reduce the feed of hot fluid into the gap between the shaft () and the cooling ring (), with the additional seal () being formed as a brush seal.
