ABSTRACT:
An improved mechanical seal of the cartridge-type providing an inboard compressed packing seal between dual shaft sleeves and the pump shaft, compressed between the shaft sleeves by action of a plurality of radially arranged set screws. A sharp edge loaded gasket arrangement between axially stacked components which make up the rotary face, the stationary face, the bellows assembly and gland is provided. The axially stacked arrangement is reversible to accommodate either a stationary bellows or rotary bellows application. An annular channel between inner and outer shaft sleeves provides a flow channel for quench fluid flowing annularly inboard to the seal faces and outboard to a quench fluid exit, providing for a uniform annular quench flow.
