Abstract
A cartridge seal assembly includes a rotatable seal ring and a non-rotatable seal ring forming a mechanical face seal. A plurality of resilient elements disposed in a housing between a stop surface and the non-rotatable seal ring provide a biasing force to urge the non-rotatable seal ring towards the rotatable seal ring. The non-rotatable seal ring includes an inner axial side opposite the annular non-rotatable seal face that forms a plurality of slots that are arranged peripherally around the inner axial side between adjacent pairs of nubs disposed on and protruding from the inner axial side in a direction away from the annular non-rotatable seal face; wherein each of the plurality of slots abuttingly receives therein a closed end of a respective one of the plurality of resilient elements to provide an anti-rotation function between the housing and the non-rotatable seal ring.
