The stuffing box is comprised of a housing which includes a main body portion and a generally tubular neck portion which extends outwardly from the main body portion. The housing has a bore through the neck portion and the adjacent part of the main body portion. The housing has at least one slot opening generally radially through the neck portion in communication with the bore. A housing flange extends generally radially outwardly from the neck portion adjacent the slot. A shaft is received in the bore for movement with respect to the housing. An annular seal is provided within the bore surrounding the shaft. A gland is provided which is comprised of a compression unit disposed at least partially within the bore adjacent one end of the seal, and a gland flange adjoining the compression unit and extending laterally outwardly through the slot. The gland is movable in a first longitudinal direction toward the seal to compress the seal. A threaded adjusting unit is provided operatively interengaged between the housing flange and the gland flange to move the gland in the first direction. The adjusting unit has a rotatable engagement portion engageable to operate the adjusting unit, the engagement portion being disposed on the opposite side of the housing flange from the gland flange.</p> |
