Abstract
A scavenger pump seal and radial shaft seal assembly therewith are provided. The scavenger pump seal includes an inner case configured for fixed attachment to a shaft for conjoint rotation with the shaft and an outer case configured for fixed receipt in a housing in which the shaft rotates. The inner case has an innermost wall sized for a press fit on the shaft and an outermost wall. An absorbent member is fixed to the inner case with the outermost wall overlying the absorbent member, thereby preventing the absorbent member from moving radially outwardly. The outer case has an outermost wall sized for fixed receipt in the housing, and facilitates preventing the egress of oil to the external environment.
