ABSTRACT:
A filtering system for a pump shaft seal includes a filter for preventing abrasive, fibrous, or other solid materials from entering the region of the stuffing box of the pump in the proximity of the seal. The filter is mounted on the pump shaft between the pump impeller and the seal, adjacent a recirculation flush port of the pump. A venturi draw is used to continuously draw fluid from between the filter and the seal and webs arranged on the rotating filter cause a localized back flushing of the filter to remove accumulated solid material from a front face of the filter.
