• Self-Cleaning Action: The centrifugal force generated by the rotating metal bellow leaflets actively throws solids away from the seal face, maintaining a clean operating environment.

• Hastelloy Construction: Manufactured with Hastelloy® C-276 bellows as standard to resist stress corrosion cracking in chloride-rich environments like tannery or chemical waste.

• Face Lubrication Control: Features specialized face groove geometry to maintain a fluid film even during the dry-start conditions common in vertical storm water pumps.

• Heavy-Duty Drive: Utilizes substantial drive pins or keys to transmit high torque loads during the start-up of large propellers.

• Debris Shedding: The smooth, flexible outer profile of the rubber bellow prevents rags, hair, and fibers from winding around the seal (ragging).

• Axial Flexibility: The highly elastic bellow compensates for significant shaft end-play and misalignment, common in aging submersible pumps.

• Optimized for Oil: The face geometry is designed to maintain a stable oil film, ensuring long life and preventing oil leakage into the stator housing.

• Corrosion Immune: Ceramic is immune to the acidic corrosion that can sometimes attack carbide binders, making it a safe choice for the motor-side seal.

• Sintered SiC: We use high-grade Sintered Alpha SiC for maximum hardness and chemical inertness, superior to reaction-bonded grades in acidic media.

• Grip-Loc Compatibility: Engineered to match the specific installation dimensions of modern "Griploc" style seals used in Flygt N-pumps.

• Brazed Face Technology: For metal bellow versions, the TC face is vacuum brazed to the holder, ensuring it cannot spin out under high torque.

• Corrosion Resistant Binder: We use a Nickel-binder TC grade to prevent "leaching" corrosion in acidic mine waters or low pH sludge.
