Claim:
1. A sealing and loading assembly for a mechanical fluid seal for sealing a shaft, the sealing and loading assembly, comprising: a housing having an annular channel surrounding a bore for housing the shaft, the channel having a first axial wall, a second axial wall axially opposite the first wall, and a radial bottom wall extending axially between the first and second axial walls, wherein the first axial wall, the second axial wall, and the radial bottom wall are monolithically formed as a single piece; a plurality of sealing elements disposed within the channel and disposed in contact with the bottom wall of the channel; and a loading assembly disposed completely within the channel between the plurality of sealing elements and the first axial wall of the channel for providing an adjustable axial loading force to the plurality of sealing elements, the loading assembly including: wherein the foot portion of the loading assembly contacts and is biased against the first axial wall of the channel and the rail element of the loading assembly contacts and is biased against at least one of the plurality of sealing elements such that upon rotation of the adjusting element of the loading assembly with respect to the one or more nut elements the rail element moves axially within the channel so as to apply an axial biasing force to the plurality of sealing elements so as to compress the plurality of sealing elements against the bottom radial wall of the channel.
