Benefits
- The mechanical seal is used with quench (unpressurised buffer fluid) for pumps handling hot water or thermal oils to prevent dry running or cracking of the thermal oil when in contact with atmospheric oxygen.
- Combined with KSB's 4HL single mechanical seal this is an optimum sealing solution for demanding fluids.
- The design facilitates installation with no need for assembly fixtures or adjusting dimension.
