MOR MFLWT 80 is a heavy-duty, rotating, single-end, balanced metal bellows mechanical seal engineered for demanding industrial pump applications involving high temperatures, corrosive fluids, and abrasive media. It features a robust welded metal bellows design that eliminates dynamic elastomers, ensuring exceptional reliability and long service life in severe operating conditions. This seal is widely used as a direct replacement for equivalent models in centrifugal pumps, process pumps, and pipeline pumps.
Features
Rotating Metal Bellows Unit: The bellows assembly rotates with the shaft, providing consistent axial compensation for wear, thermal expansion, and shaft misalignment.
Balanced Seal Face Geometry: Reduces face loading to minimize friction and heat generation, enabling operation at higher pressures and speeds.
No Dynamic Elastomers: Eliminates elastomer fatigue, swelling, or degradation in high-temperature or corrosive environments.
Robust Drive Mechanism: Features a positive drive collar with set screws for reliable torque transmission, regardless of shaft rotation direction.
Compact & Interchangeable: Fits standard pump cavities and is designed for easy installation, maintenance, and direct interchangeability with similar seals.
Advantages
Extreme Temperature Resistance: Performs reliably in conditions where elastomer-based seals fail.
Long Service Life: No dynamic elastomers reduce wear and minimize maintenance requirements.
Corrosion & Abrasion Resistance: Wide material selection adapts to aggressive and abrasive fluids.
Versatile Performance: Balanced design ensures stable operation under high pressure and speed.
Interchangeability: Direct replacement for John Crane Type 609, C65, and other equivalent metal bellows seals.
Applications
Petrochemical & Refining: Crude oil, hot oil, gasoline, diesel, and lubricants
Chemical Processing: Acids, alkalis, solvents, and other corrosive fluids
Power Generation: Boiler feed water, thermal oil, and condensate
Pulp & Paper: Black liquor, white liquor, and abrasive slurries
Pharmaceutical & Food: High-temperature clean process fluids
