ABSTRACT:
A sealing system for a rotatable shaft positioned in a passage extending through a housing where both static and dynamic sealing are achieved to prevent fluid leakage along the shaft from the liquid side to the air side of the seal. The system includes a helix formed either on the shaft or on the wall encompassing the shaft to provide a viscous shear pump forming a hydrodynamic seal, and a temporary face seal is provided at the air side end of the helix and adapted to effectuate sealing under static conditions and to diminish face seal contact upon rotation of the shaft.
