ABSTRACT:
In a split mechanical face seal including means for biasing one split seal face against another, an annular, inwardly radially extending leaf spring, which may also be split, is mounted at an outer diameter thereof to the stationary seal housing. A radially inward end of the spring is received in a notch in the stationary seal ring axially remote from the sealing face. The spring end biases the seal face toward a non-resiliently mounted rotating face and retains the stationary sealing face against rotation. A tool in the form of a U-shaped collar is provided for holding two split ring seal halves for preventing grinding motion at their mating surfaces during installation.
