Abstract

An energy diffusion sealing ring for use with a hydrocyclone or pump is provided. The energy diffusion sealing ring comprises a sacrificial suspension matrix comprised of a polymer elastomer or combination thereof and a number of packed inserts suspended in the matrix. The matrix serves as delivery means for the inserts into one or more recessed portions. The inserts comprise a hard material (e.g. ceramic or carbide) and form wear bodies which slow and dissipate kinetic energy of escaping slurry by way of creating paths of resistance. As the suspension matrix erodes over time a plurality of interstices between the inserts are formed. Escaping slurry slows as it traverses three dimensional serpentine paths defined by said interstices thereby reducing its potential to wear surrounding components. Methods for manufacturing an energy diffusion sealing ring and for dissipating the energy of slurry are also disclosed.
