    Abstract: An energy diffusion sealing ring [872] for use with a hydrocyclone or pump is provided. The energy diffusion sealing ring [872] comprises a sacrificial suspension matrix [872A] comprised of a polymer, elastomer, or combination thereof, and a number of packed inserts [872B] suspended in the matrix [872]. The matrix [872] serves as delivery means for the inserts [872B] into one or more recessed portions [833, 841]. The inserts [872B] 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 [872A] erodes over time, a plurality of interstices [872C] between the inserts [872B] are formed. Escaping slurry [852] slows as it traverses three-dimensional serpentine paths defined by said interstices [872C], thereby reducing its potential to wear surrounding components.
