An exchangeable separation insert for a centrifugal separator includes a rotor casing enclosing a separation space in which a stack of separation discs is arranged, and first and second stationary portions. A feed inlet supplies a fluid mixture to the separation space. The insert includes a light phase outlet and a heavy phase outlet. The feed inlet is arranged at a first axial end of the rotor casing. One of the light phase outlet and heavy phase outlet is arranged at a second axial end. A first rotatable seal seals and connects the feed inlet and a second rotatable seal seals and connects one of the light phase outlet and heavy phase outlet.
