ABSTRACT:
A quenching mechanism for slurry pumps comprises a radial or inclined array of grooves at the rear end of a rotary seal ring. A quenching water, flowing along a fixed seal ring and through a gap between both the seal rings and a baffle sleeve, is forced to flow to the outer periphery of the rotary seal ring by the pumping action of the grooves, thereby achieving an increased cooling effect.
