Abstract
A drum is for a rotary separator including a shaft rotatable about a central axis. The drum includes an inner drum member having inner and outer circumferential surfaces and being disposed generally about the shaft such that a first flow passage is generally defined between the inner drum member inner surface and the shaft. The inner drum inner surface is configured to separate liquids from a fluid flow contacting the surface. An outer drum member has inner and outer circumferential surfaces and is disposed generally about the inner drum member such that a second flow passage is generally defined between the outer drum member inner surface and the inner drum member outer surface, the second flow passage being generally coaxial with the first flow passage. Further, the outer drum inner surface is also configured to separate liquids from a fluid flow contacting the surface.
