Abstract
A seal, for use with pump casing elements that are adjustable relative to each other, includes an annular band and a resilient annular flange oriented at a non-perpendicular angle to a first surface of the annular band such that the seal, in use, is able to provide greater adjustment between the adjustable pump elements while maintaining a reliable seal between the pump elements.
