A separator for centrifugally processing includes a rotatable drum having at least two drum parts, which can be rotated relative to one another at a screw thread. A drum tool is designed to open and close the drum by rotating the drum parts screwed together by the screw thread. The drum tool includes a retaining element attachable to the one drum part, a driver element attachable to the other, relatively rotatable drum part, and at least one rotation device for the relative rotation between the retaining element and the driver element together with the drum parts. The retaining and driver elements each having two or more points of engagement for the rotation device. The points of engagement are symmetrically arranged in such a way that forces produced by the rotation device produce a torque for the relative rotation of the drum parts, but no resulting force acting on the screwed drum parts on one side is produced.

A seal arrangement for a process device or installation. A component arrangement has two components adjoining one another in sections in the area of a gap. A groove toward the gap is formed on one of the two components, which groove is L-shaped and is open toward an edge of the gap. A seal is inserted into the groove, which seal also has an L shape that corresponds to the L shape of the groove, for which purpose the seal has a first sealing limb and a second sealing limb at right angle thereto. The first sealing limb is designed so that the first sealing limb is inserted into the first limb of the groove, and the second sealing limb is designed in such a way that the second sealing limb can be inserted into the second limb of the groove and is firmly clamped there, and the first sealing limb is firmly clamped into the first limb of the groove in the manner of a sealing foot with oversize.

A separator for centrifugally processing a flowable product includes a rotatable drum bounding a centrifuging chamber. The drum has a feeding and removal system having at least one feeding device and one or more removal devices composed of plastic or a plastic composite. An inner drum, composed of plastic or a plastic composite, is arranged in an outer supporting device of the drum. The feeding device and the one or more removal devices extend into the inner drum, do not rotate with the inner drum during operation, and are glued and/or welded to each other in such a way that the feeding device and the one or more removal devices are sealingly connected. The feeding and removal system has one or more grippers as the removal device, each of which one or two or more grippers has a disk segment and a shaft segment.

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.
