Abstract:
A kit for sealing about a rotatable member extending through a machine housing, the kit including:a follower housing connectable to the machine housing and of annular form for mounting about the rotatable member with an axial direction of the follower housing aligned with the rotational axis of the rotatable member, wherein the follower housing includes spaced apart inner and outer annular walls encircling the rotatable member; a follower for compressing packing which is disposed within a recess of the machine housing against the rotatable member, the follower having an annular body portion slidingly engageable with both the inner and outer annular walls of the follower housing, the follower being slidable within the follower housing generally in the axial direction and having sliding interfaces for interfacing with the inner and outer annular walls of the follower housing; an annular chamber encircling the rotatable member, the annular chamber being at least partially defined by the inner and outer annular walls of the follower housing and an annular pressure face of the follower, the chamber having means for receiving fluid; and secondary sealing means at the sliding interfaces for sealing against the egress of fluid from the chamber along the sliding interfaces of the follower.
