Abstract
A sealing arrangement for a rotating shaft, which is in particular designed as a drive shaft of a pump, has a stationary seal holder in which a first and a second slide ring seal are supported. The slide ring seals each have a co-rotating rotary seal part and a stationary seal part. A sealing space is formed between the slide ring seals and the seal holder to which sealing fluid can be supplied via a feed line. In order to enable good rotor dynamics of the shaft with the seal arrangement, a bearing is arranged between the first and the second slide ring seals by means of which the shaft can be supported with respect to the seal holder.
