ABSTRACT:
A pump has a pair of seal parts which are arranged to undergo axial translatory motion and a seal assembly associated with the seal parts. The seal assembly includes an annular liner disposed within a groove in one seal part and projecting therefrom toward a cylindrical surface of the other seal part, and a flexibly resilient annular O-ring disposed within the groove between the cylindrical surface of the other seal part and a surface of the liner which extends generally parallel to the cylindrical surface of the other seal part. The O-ring is seatable on a radial surface of the annular liner and projects from the groove farther across a gap between the seal parts than the liner and into contact with the cylindrical surface of the other seal part such that the O-ring is capable of rolling on the cylindrical surface of the other seal part and slipping on the radial surface of the annular liner upon translatory movement of the seal parts relative to one another.
