Unique Internal Cartridge Seal for highly corrosive fluids.

Tribological components and o-rings shield all other parts from fluid - a feature previously reserved for External Seals only.

Internal mounting of face facilitates superior performance in the presence of suspended abrasive solids.

"Mount and Start" design - no setting tabs to be removed and lost.

Narrow cross section for tight space.  

Temperature, pressure and speed limits are application and materials dependent.
