<p>An apparatus for retaining a liquid phase which may include solid materials between a fixed wall and a rotary member passing therethrough. A seal is thereby provided which eliminates friction while accepting limited leakage of the liquid phase. The apparatus includes: (a) a partition member which is fixed with respect to the rotary member and the periphery of which has at least one planar surface which is perpendicular to the axis of rotation of the rotary member. This forms a bearing surface, and a surface which is concentric to the axis and which is joined to the bearing surface; (b) a retaining ring which is positioned on the planar surface and the concentric surface of the partition member, and which is fixed with respect to the rotary member; and, (c) a collar joined to the wall and having an inside diameter that is at least equal to the outside diameter of the ring. The collar is longitudinally positioned on the wall through which the rotary member passes, and has an adjusting and locking device for preventing rotation thereof.</p> |
