7. FAQ

Q: What information is needed to confirm the exact configuration of the CB6687-2L seal?

To ensure exact replacement, please provide the exact shaft diameter (mm or inches), the pump make/model, the pumpage fluid (media, temperature, concentration), and the letter suffix on your existing Pillar nameplate (which indicates face and O-ring materials).

Q: Can the CB6687-2L be refurbished or re-lapped if the faces get scored?

Yes. If the stainless steel sleeve and gland housing remain undamaged, worn silicon carbide or carbon seal faces can be professionally re-lapped or replaced using genuine NIPPON PILLAR repair kits to restore original factory sealing tolerances.

Q: How are these mechanical seals prepared for long storage periods?

All PILLAR CB6687-2L units are stored in clean room conditions with protective face covers, wrapped in corrosion-inhibiting vapor barrier packaging to keep elastomeric O-rings soft and seal faces pristine for up to 5 years.
