A spiral guide (32) is positioned in annulus (30) between the concentric tubular members (20, 22). A wear structure comprising the present invention includes a flat (38) in the outer wall (27) of the outer tubular member (20) to provide a reduced thickness wall portion thereat. Upon wear from abrasive solid particles, and opening (40) is formed at the reduced thickness cutaway portion defined by flat (38). A sleeve (46) may be mounted within the outer tubular member (20) below the inner tubular member (22).
