Beschreibung
Zusammenfassung:	The invention relates to a shaft seal (SS), which comprises more than one sealing module (SM), at least one fluid supply (FF) and a fluid discharge (EX), comprising a primary seal (MS1) which is subject to the greatest partial pressure difference (???). Conventional shaft seals of said type usually require significant amounts of additional sealing fluid (SF) in order to ensure suitable pressure gradients. The invention provides a solution by designing the second primary seal (MS2) as a radial double seal (RDS), which is determined by two gas seals (DGS), each having a rotating sealing surface (RSS) and a stationary sealing surface (SSS), which sealing surface pairs (SSP) are located opposite each other in a sealing plane (SEP), wherein the two sealing planes have a substantially radial extension to the shaft (S).
