Abstract
A non-contact seal for rotatable shafts includes a stator ring and a rotor ring with internal pumping discs. Each of the, the stator ring pumping discs, and the rotor ring is split diametrically into two halves for mounting on a rotatable shaft at an intermediate station without having access to the end of the shaft or without having to remove other components. Various sealing components are employed between the split rings to prevent fluids within the seal from leaking out.
