Slurry Seals - RIS

About this product

The RIS seal has a unique, non-clogging design that does not utilize springs or bellows. The innovative design of the adaptive components allows the seal to be installed from the wet-end of the pump and to be adjusted externally. With many pump designs, the seal may be reset automatically during impeller clearance adjustment.

Features and Benefits

  • A smoothly contoured flexible rubber element holds the seal faces together and absorbs relative shaft movement when the pump is in operation.
  • A true non-clogging design provides longer MTBF with the rubber in shear component.
  • External adjustment capability compensates for minor seal wear with no pump disassembly and compensates for pump misalignment.
  • No dynamic o-ring provides for longer MTBF by eliminating seal face hang-ups.
