A mechanical rotary seal that produces a positive drive force so that all components of the seal rotate in unison upon a rotating shaft. The mechanical rotating seal effects a tight fluid seal between a submersible pump housing and a rotating shaft when the mechanical rotary seal is engaged with a stationary seal or element within the submersible pump housing. The mechanical rotary seal comprises a seal housing, a retainer having a seal face for engaging with the stationery seal and a coil spring between the seal housing and the retainer. A mechanism for positioning and locking the mechanical rotary seal onto a rotary shaft is positioned within the rear section of the seal housing
