An axially-split turbomachine comprising a casing comprised of a first casing portion and a second casing portion, forming a housing for a rotor arranged for rotation therein. The rotor comprises a shaft and at least one impeller mounted on the shaft. The casing comprises at least one shaft passageway through which the shaft extends from the interior of the casing towards the exterior of the casing. The sealing arrangement comprises a linear sealing member, extending between the first and the second casing portions. The sealing arrangement further comprises at least one sealing ring portion surrounding said at least one shaft passageway. The sealing ring portion and the linear sealing member form a continuous sealing body.
