Abstract

A pump bushing device (10) that is adapted and configured to admit pressurized flushing fluid into a seal cavity of a pump, flushing debris therefrom without removal of the pump bushing device, including a cylindrical body (12) defining an axial bore (14) extending therethrough for accommodating a shaft of a pump; a plurality of circumferentially spaced-apart, axially-extending, angled slots (16) formed in an inner peripheral wall of the axial bore; and a plurality of apertures (20) extending radially inward at an angle from the outer periphery of the cylindrical body to the axial bore. Wherein the plurality of angled slots and the plurality of apertures receive pressurized flushing fluid.
