ABSTRACT:
A mechanical face seal assembly has a cylindrical retainer fixedly mounted between a rotating shaft and a stationary housing. The rotating shaft defines a longitudinal axis and a rotating sealing ring rotates with the shaft. The rotating sealing ring is axially offset from the retainer. The retainer includes inner and outer legs which extend longitudinally along the axis and are radially spaced with respect to each other. The assembly also includes a non-rotating washer disposed within the retainer. A spring biases the washer towards the sealing ring. The invention also includes a method of easily assembling a seal by deforming an outer leg of the retainer after assembly of the seal components.
