A separator for separating substances having relatively high densities from a flow stream, the separator operating at a first pressure comprising: a shaft; a drum connected to the shaft, and adapted to rotate to separate the substances having relatively high densities from the flow stream, wherein at least a portion of the flow stream flows through a region at least partially defined by an inner surface of the drum; at least one bearing assembly for supporting the shaft; and a first housing; a second housing, wherein the at least one bearing assembly is disposed in one of the first and second housings; the separator characterized in that the separator includes: means for permitting the at least one bearing assembly to operate at a second pressure substantially corresponding to the first pressure, wherein the permitting means comprises: a reservoir operating at a second pressure substantially corresponding to the first pressure; a passage at least partially extending within the one of the first and second housings and in fluid communication with the bearing assembly; and at least one line fluidically connecting the passage and the reservoir.
