Abstract

See full text

A centrifugal separator for separation of a liquid mixture includes a stationary frame, a rotatable assembly and a drive unit for rotating the rotatable assembly relative the frame around an axis of rotation, wherein the rotatable assembly includes a rotor casing enclosing a separation space in which a stack of separation discs is arranged to rotate around a vertical axis of rotation. The rotor casing includes a mechanically hermetically sealed inlet for supply of the liquid mixture to the separation space; a first liquid outlet that is mechanically hermetically sealed and arranged for discharge of a separated liquid phase and a second liquid outlet that is mechanically hermetically sealed and arranged for discharge of a separated heavy phase, the heavy phase having a density that is higher than said liquid phase. The separator further includes at least one positive displacement pump arranged downstream of the second liquid outlet for transporting the separated heavy phase from the separation space and at least one positive displacement pump arranged downstream of the first liquid outlet for transporting the separated liquid phase from the separation space.
