Zusammenfassung:	An improved drive for a banded sealing ring or washer in a rotary mechanical seal. The washer, usually a ceramic washer, is provided with an annular band surrounding its outer periphery which includes an outwardly extending flange. The seal includes a sleeve mounted on a rotatable shaft of a pump, which houses the washer in coaxial relation. It further includes a flange extending radially, which defines means in contact with the band of the washer, such that driving engagement is effected between the sleeve flange and the washer band and the washer is caused to rotate with the sleeve.
