<p>A remotely actuated packing follower for compacting the packing (19) in a base (14) and base extension (15) situated around a rotatable or longitudinally pulsatable shaft (7) exiting a structure. The remotely actuated packing follower comprises a piston (31) slidably and sealingly mounted within a housing (32) and a packing follower cap (30) sealingly attached to the top (66) of the housing (32). Preferably, the packing follower cap (30) has a channel (54) for fluid from a remote source to flow from a hose attached to the channel (54). The piston (31), housing (32), and packing follower cap (30) create a chamber (46). When sufficient fluid flows into the chamber (46), it pushes the piston (31) away from the packing follower cap (30) so that the bottom (57) of the piston (31) can push against the packing (19). An inner channel (49) in the piston (31) accommodates the shaft (7). Either the remotely actuated packing follower or a traditional anti-leak fitting is optionally constructed of releasably connectable sections (67, 68, 69, 70, 80, 81, and 82).</p> |
