Abstract:
A mechanical seal assembly has rotational and stationary sealing members) and a drive unit, which is axially adjacent one of the sealing members. An energizing member urges the drive unit towards the sealing members. A retainer axially and radially retains one of the sealing members. The drive unit is in contact with one of the rotational and stationary members by way of contacting surfaces which are in the range of 1 and 20 light bands of flatness, inclusive.

Claim (Index 1):
