Zusammenfassung:	The invention relates to a shaft seal (1), arranged to seal a rotatable drive shaft (2) from a high pressure area. The shaft seal (1) comprises a shaft seal housing (3), a first seal (10) and a second seal (20), wherein the first and second seals (10, 20) are positioned around the drive shaft (2) at different axial positions. A chamber (4) is created in between the first (10) and second seal (20), wherein the shaft seal (1) comprises a fluid supply (74-78) for supplying a pressurized fluid to the chamber (4). The first seal (10) is a mechanical seal positioned between the high pressure area and the chamber and the second seal (20) is a lip seal.
