ABSTRACT:
A seal ring seals a shaft in a housing dynamically and statically. The dynamic seal function is provided by a porous compact which rotates with the shaft to pump liquid media centrifugally back into the sealed space and generally radial, inward channels which similarly pump gases which penetrate the compact to the channels. An annular gas impingement surface is spaced from the discharge ends of the channels at an obtuse angle to entrain the pumped gases back into the sealed space. The static seal centrifugally opens upon rotation.
