ABSTRACT:
A package seal particularly suited to pumps or other applications having a drive shaft which terminates internally of a housing at its connection to the impeller or fluid working element. In such an apparatus partial disassembly of the components provides access to the free end of the drive shaft. The package seal has an outer member adapted to be disposed coaxially on the rotatable shaft and pass through the housing bore. The outer member includes a mounting flange adapted to be secured in the interior of the housing and a cylindrical body adapted to extend axially along the rotatable shaft from the seal flange to the exterior of the housing. The cylindrical body houses the seal components which provide a fluid tight seal between the housing and shaft.
