Abstract
A seal seat assembly utilizes a positive mechanical drive between a seal seat and the bore of a pump component, which in turn is mounted to and driven by the shaft by means of a positive mechanical engagement therebetween. The grommet accommodates the positive mechanical drive between the seal seat and the pump component. The seal assembly enables a robust, easily assembled three-component sub-assembly of the seal seat, grommet and pump component that can be handled as a single unit, and which easily installs onto, seals with, and becomes rotationally locked to a shaft. The positive engagement features, retaining features and static sealing features are axially aligned to provide an axially-compact seal assembly.
