Stuffing box for high density screw pump and pump incorporating same

摘要

An axially fixed, radially limitedly movable stuffing box assembly including mounting means therefor. The stuffing box is adapted to have means for continuously flushing its bushing during operational rotational movements of a shaft functionally engaged therewith. The stuffing box when used in functional combination with a screw of a screw pump which is itself adapted for the pumping of high density fluids greatly reduces the tendency for radial forces generated during pumping to cause shaft deflection and to produce shaft wear and leakage.
