Abstract: An apparatus for restricting flow of a fluid along a shaft passing through the apparatus while permitting the shaft to freely rotate can include a housing, a gland follower, a fastening mechanism, and a biasing mechanism. The gland follower may include a center aperture for receiving the shaft and at least one fastening aperture. When installed, the fastening mechanism mechanically couples the gland follower to the housing to define a cavity in conjunction with a recess within the housing. Also, the biasing mechanism generates a predetermined force when installed that biases the gland follower towards the housing in a direction parallel to an axis of rotation of the shaft. The predetermined force can be translated into a force that deforms packing material inserted into the cavity to provide sealing engagement with the shaft.

Abstract: A shaft support and lubrication system can include two vise bearings, a lantern ring, and two or more sets of packings. The vise bearings can be rigid cylinder tubes. The lantern ring can be a flexible cylindrical tube with one or more outer grooves on an outer diameter, one or more inner grooves on an inner diameter, and one or more through holes from either the outer diameter or the one or more outer grooves to either the inner diameter or the one or more inner grooves. When arranged coaxially and installed on a shaft, the shaft support and lubrication system provide physical stabilization and provide lubrication or cleaning solution to the shaft.

Abstract: A lance tube stuffing box assembly includes within a seal cavity, a first and a second sleeve bearing oriented to be axially aligned with the bore and with each other and spaced apart within the bore to define a packings space. A plurality of braided packings are situated within the packings space and oriented to be axially aligned with each of the first and second sleeve bearings; and inserted within the bore in opposed relation to the annular wall of the seal cavity a gland follower which is likewise axially aligned and bears against the first bearing with an axial force to narrow the packings space, urging the plurality of braided packings to expand radially, such that when a lance tube is inserted axially. The axial force causes the braided packings to sealingly engage the lance tube.
