ABSTRACT OF THE DISCLOSURE Improved spiral grooves in a mechanical face seal have plural terminal corners which more evenly distribute the fluid pressure generated within the seal gap into discrete pressure zones which are radially displaced and may also be circumferentially displaced from the other pressure zones generated by the same groove. Alternative embodiments include grooves having surfaces of varying depths wherein each of the plural terminal groove corners is associated with a section of the groove having a surface at a particular depth.
