Direct Coupling of a Vortex Injector to a Centrifugal Pump Abstract A method for reducing the wear on the impeller and increasing the efficiency of a centrifugal pump when used to pump a slurry stream containing from large dimensioned to fine dimensioned material in a fluid by forming a vortex by injecting fluid tangentially into a circular chamber and removing a portion of said fluid tangentially from said chamber; injecting said slurry axially into said chamfer, said vortex separating said large dimensioned material from the remainder of said slurry and fluid; removing said remainder of said slurry and fluid axially from said chamber and injecting same into the inlet of a centrifugal pump; and using the output from said centrifugal pump as the injected fluid for said vortex.
