Unique Cartridge Construction simplifies installation, enables more accurate seal setting, and keeps associated costs low.

Triple Redundant Seal Design mirrors existing seal system parameters. Each of the three stages can handle 100% of the system pressure.

Hydrodynamic Seal Face Technology outperforms hydrostatic designs with dramatically improved reliability and running periods.

Three different seal face lift designs are available to ensure non-contacting faces over a broad operating range.

Pressure is Automatically Redistributed to the remaining two stages in the event of a stage failure, allowing the plant to complete the fuel cycle.

Interchangeability of Stage Components enables spare parts inventories and carrying costs to be reduced.

Large Axial Travel Capability maximizes operating life; sealing integrity maintained through all plant transient scenarios.
