  • 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.
