摘要： A self piloting seal assembly for use on a rotatable shaft pump unit, the seal assembly including a seal head assembly in constant contact with a seal seat assembly. The seal head assembly includes an elastomer boot, a spring seat, a ferrule and a spring all disposed around a seal washer. The seal seat assembly includes a ceramic radial seal seat disposed within an elastomer boot member. The seal washer is in constant contact with the seal seat assembly to prevent leakage of any fluid between and around the shaft member.

摘要： A unitized seal impeller thrust system includes an impeller unit which includes a tubular neck portion that has flat surfaces on opposite sides of one another. The impeller unit includes a plurality of radially extending blades and a circular trough surrounding the neck portion. The system further includes a seal head assembly which is secured within the trough, and a seal seat assembly which engages the seal head assembly. The system further includes a thrust washer which engages the seal seat assembly and the retainer ring which is secured to the tubular neck portion at an end of the neck portion. The retainer ring also engages the thrust washer in a ball and socket type arrangement. The system provides a unitized seal, impeller, thrust system that is capable of preload testing and/or leak testing before assembly of the pump unit.
