• Dry-Run Tolerance: When paired with a specialized dry-running Carbon face, this seal can handle the vapor phase in the top of a mixing tank.
• Large Clearances: Designed with larger internal clearances to accommodate the shaft deflection (wobble) inherent in mixing applications.
Key Features
• Mixer Duty: Designed for top-entry and side-entry mixers in the food, pharmaceutical, and chemical industries.
• Chemical Inertness: Alumina Ceramic faces resist attack from a wide range of acids, alkalis, and salts used in mixing processes.
• O-Ring Mounted Seat: The stationary seat is mounted on O-rings to provide vibration damping, protecting the brittle ceramic from the shaft runout common in long mixer shafts.

Workshop
This workshop is equipped with professional processing equipment and integrated with standardized material warehousing management, enabling a one-stop production process from precision machining to finished product delivery. It ensures part machining accuracy and production efficiency, meeting various high-specification manufacturing requirements.
Product Research, Development and Testing
Our Product R&D and Testing focuses on optimizing seal performance through advanced simulation and material analysis. All seals undergo rigorous trials, including thermal cycling and pressure tests, to ensure durability, minimal leakage, and long service life in demanding industrial environments.
Industry Solutions
Case Study
Chemical Agitator: A paint mixing tank seal failed due to solvent attack on the face binder. We replaced it with a Solid Alumina Ceramic seal. The inert ceramic resisted the solvents completely, ensuring batch purity.
Testimonials
We put these on our side-entry agitators. The ceramic faces hold up well against the chemical slurry we mix.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Can ceramic handle the vibration of a mixer?
A: Ceramic is strong but brittle. Our design uses heavy-duty O-rings to "float" the ceramic seat, absorbing the vibrations and preventing cracking. For extreme vibration, Silicon Carbide is recommended.
Our company is specialized in the production of sealing materials, mechanical seals , cartridge seals.
