<p>A seal system including a sleeve configured to receive a rotatable shaft therein and a dynamic race configured to be rotatably coupled to the shaft. The seal system further includes a biasing element configured to urge the dynamic race into engagement with a static race to form a primary seal, and a shroud configured to be rotatably coupled to the sleeve and positioned radially outside the biasing element. The seal system also includes a sealing element configured to be positioned radially inside the biasing element and to sealingly engage the sleeve to provide a secondary seal to generally block fluid bypassing the primary seal.</p> |
