ABSTRACT:
The liquid being handled is introduced through a centrifugal conduit 1, is separated according to the different density and the two liquid phases exit through conduits 4 and 5. The centrifugal separator comprises disks for sealing (6, 11 and 19) which are fixed respectively to the central part of the rotor 7 to the middle disk 12 and to the upper cover 20 of the apparatus against which the moveable shaped rings (8, 13, 14 and 17) press. The movable rings are subjected to the pressure of the liquid being introduced into the separator as well as the pressure of the two liquid phases being separated by centrifugation due to the difference in specific weight. In this manner, a perfect seal between the different phases is ensured, no biasing means are needed and there is no necessity of particular external cooling.
