• 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.

• Electropolished Metal: All wetted stainless steel parts are electropolished to reduce surface roughness and improve corrosion resistance.

• Flush Connection: Integrated flush ports allow for steam quenching or water flushing to keep the faces clean and sterile.

• Face Flatness Stability: Vertical pumps can have shaft runout; our Alumina Ceramic seats are lapped to extreme flatness to maintain a seal even with minor shaft wobble.

• Thermal Conductivity: High-purity alumina dissipates heat generated by dry-running incidents (common in tank emptying) better than lower grade ceramics.

• Bonded Face Technology: The ceramic ring is securely bonded to the stainless steel holder to prevent rotation and leakage under torque load.

• Cost-Efficiency: Provides a significant cost saving over Tungsten Carbide seals for non-abrasive applications or secondary sealing duties.

• Friction-Welded Faces: In some configurations, the ceramic face is bonded directly to the seat holder to ensure stability under thermal cycling.

• Optimized Spring Rate: The coil spring force is calibrated to maintain face contact without causing excessive wear on the ceramic face during dry-run startups.

• Oil-Lubricated Design: The face geometry is optimized to maintain a lubrication film from the oil chamber, preventing dry running friction on the ceramic face.

• Resilient Mounting: The ceramic seat is mounted in a generous rubber cup to absorb the vibrations inherent in submersible pump operation.
