Abstract: A self-draining separator for centrifugal separation of a suspension into a light liquid phase, a heavy solid phase, and a moderately heavy intermediate phase. The separator includes a rotatable centrifuging drum, a liquid discharge for the light liquid phase, a discontinuously active solid matter discharge opening for the heavy solid phase, to which a first actuatable discharge device is assigned, by way of which the solid matter discharge opening can be discontinuously opened and closed. The separator also includes a discontinuously active discharge opening for the intermediate phase, to which at least one second actuatable discharge device is assigned, by way of which the discharge opening for the intermediate phase can be discontinuously opened and closed again.

Abstract: A separator includes a frame and a separator insert exchangeably disposed on the frame. The separator insert is designed to separate a flowable suspension into at least two flowable phases of different density in a centrifugal field and forms a preassembled, exchangeable unit for inserting into stator units on the frame of the separator. Mutually spaced holders having stator units of the bearing devices are formed on the frame, between which holders the housing of the separator insert is non-rotatably retained such that the rotor with the drum remains rotatable. The relative position of the holders can be changed such that the separator insert can be exchanged. The housing and the holders have corresponding interlocking elements in order to non-rotatably retain the housing at the holders.

Abstract: A method for lowering the pressure inside the hood interior of a separator arrangement with a separator with a rotatable drum includes rotating the rotatable drum about a vertical rotation axis. Before processing a product that is to be processed, a liquid is first directed through the drum and the pressure inside the hood interior is lowered, by a device, as a result of rotations of the drum in the manner of a jet pump. After the pressure inside the hood interior has been lowered sufficiently, then the actual processing of the product that is to be processed is performed.
