MOR MFL95N is a rotating, balanced, single‑end metal bellows mechanical seal, designed for unstepped (smooth) shafts. It features a roller‑type metal bellows that provides both spring force and torque transmission, eliminating dynamically loaded elastomers. This seal is engineered for reliable performance in demanding process applications and complies with EN 12756 standards.
Features
Rotating Roller Metal Bellows: Unique edge‑welded roller bellows design offers high axial flexibility (±0.5 mm) and excellent resistance to shaft deflection.
Balanced Seal Face: Hydraulically balanced design reduces face loading, enabling stable operation at higher pressures and speeds.
Rotation‑Direction Independent: Functions reliably regardless of shaft rotation direction.
No Dynamically Loaded O‑Rings: All secondary seals are static, eliminating elastomer wear from axial movement and enhancing high‑temperature stability.
Self‑Cleaning Effect: The bellows geometry minimizes solids buildup on seal faces, improving performance in dirty or viscous media.
Smooth Shaft Compatibility: Installs directly on standard, unstepped pump shafts without modification.
Shaft Protection: Full‑length shaft coverage prevents wear and corrosion
Advantages
Extreme Temperature Stability: Operates reliably across a wide thermal range without elastomer degradation.
Superior Misalignment Tolerance: High axial flexibility accommodates shaft runout and seal chamber misalignment.
Low Maintenance: Self‑cleaning design and static secondary seals minimize wear and extend service intervals.
Easy Installation: Fits unstepped shafts and is rotation‑direction independent, simplifying retrofits.
Robust Construction: High‑grade alloys and roller bellows ensure durability in harsh industrial environments.
Applications
Oil & Gas: Refinery pumps, crude oil transfer, hydrocarbon processing.
Chemical & Petrochemical: Acids, solvents, hot/cold process fluids, viscous media.
Pharmaceutical & Food: Low‑end sterile applications, hygienic process pumps.
Pulp & Paper: Process pumps handling abrasive or high‑temperature fluids.
General Industry: Centrifugal pumps, compressors, and special rotating equipment.
