  • Hydrodynamic mating ring with integrated groove inlet pressure control
    Patent number: 9714712
    Abstract: A hydrodynamic mating ring of the present disclosure may include a sealing face, a hydrodynamic groove disposed in the sealing face, an impeller portion, and an inlet conduit configured to provide fluid communication between the hydrodynamic groove and the impeller portion. A method of sealing may include providing a mating ring having a sealing face, a plurality of hydrodynamic grooves disposed in the sealing face, a plurality of impeller portions, and a plurality of inlet conduits configured to provide fluid communication between respective ones of the plurality of hydrodynamic grooves and the plurality of impeller portions. The method may include rotating the mating ring, and increasing at least one of a pressure, a volume, and a flow rate of fluid to the hydrodynamic grooves via the plurality of impeller portions drawing said fluid into the plurality of inlet conduits.
