ABSTRACT:
Sealing means for controlling leakage of material between closely spaced apart, relatively moving coaxial annular surfaces. Essentially, leakage is controlled by providing a pumping channel on one of the surfaces and a leakage liquid retaining channel on the other surface. The pumping and leakage liquid retaining channels are cooperatively arranged to resist flow of leakage liquid between the surfaces. The sealing means are particularly adaptable for controlling leakage from processing passages of rotary processing apparatus.
