A rotary seal has a floating seal face in a sealing relationship with a stationary seal face, and a fluid collection cavity adjacent the floating seal face and the stationary seal face. The seal further includes a device for introducing a lubricant into the vicinity of the fluid collection cavity and a device for promoting coalescence of the lubricant, so that the lubricant accumulates in the fluid collection cavity and lubricates the seal faces.
