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- 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
