Abstract
A radial pressure adjustable gland sealing system is disclosed herein. The system includes at least one inflatable bladder operable to surround a rotating shaft or sleeve of a rotating shaft, and at least one inflating tube. One end of each inflating tube is in fluid communication with the internal envelope of one of the at least one inflatable annular bladder. An opposite end of each inflating tube is connected, or extends, to a location outside of a static housing in which the rotating shaft is housed, such that the level of inflation of each inflatable bladder can be adjusted by way of its respective inflating tube, and thereby adjust the level of radial pressure exerted on the rotating shaft or sleeve for a rotating shaft.
