ABSTRACT:
A dynamic seal is provided, comprising a gland, fixedly connectible to a housing around a rotatable shaft and having a first side, facing interior of the housing; a second side, facing exterior of the housing; a center opening, communicating between the first and second sides; and having a diameter greater than that of the shaft; an annular inner face, countersunk into the second side adjacent to the center opening so as to form an interior groove between the shaft and the gland; an annular first flange, extending axially from the inner face; and at least one relief port, communicating between the interior groove and the exterior of the gland. The seal also comprises a rotating member, fixedly connectible to the rotatable shaft and having a first face, facing toward the second side of the gland; a second face, facing away from the gland; an outer annular surface between the first face and the second face, an outer annular diameter such that the rotating member will fit within the interior groove of the gland; an annular sealing groove, having an inner wall and an outer wall, positioned in the first face so as to matingly receive the first flange of the gland and permit relative movement therebetween; a plurality of first indentations on the outer annular surface; and a central shaft opening having a diameter just greater than the shaft.
