A mechanical seal particularly well suited to use in rotary equipment handling abrasive slurries. The seal comprises a split rotary face biased toward a split stationary face by a cone spring. The cone spring is encased in elastomeric material which includes molded lugs which serve to transfer rotary motion from a drive sleeve to the rotary housing which contains the split rotary face. The seal forms a unitary cartridge which may be pre-set through the use of setting plates which establish a predetermined amount of compression of the cone spring.
