ABSTRACT:
An axially floating annular flow ring is provided for use in a gland mounted to rotary equipment concentrically to the equipment shaft. The ring has an outer circumferential surface for mounting to the gland interior adjacent to gland port mouths opening out of the gland interior surface and axially between the ends of primary seal members associated with the gland. The ring non-rotatably mates with the primary seal members and the gland, and can shift axially. The ring supplies a fluid flow channel in conjunction with fluid-flow vanes associated with the shaft and which ring can travel axially with the vanes to accommodate shaft endplay.
