Material Combinations (Optional)
Seal Faces: Carbon graphite / reaction‑sintered silicon carbide (SiC) / tungsten carbide (TC) – wear & corrosion resistant
Secondary Seals: FKM (Viton), EPDM, or FFKM (perfluoroelastomer) O‑rings for chemical compatibility
Springs: 316L stainless steel or Hastelloy – anti‑clogging, uniform face loading
Metal Parts: 316L, duplex 2205, or super duplex 2507 – high corrosion resistance
Key Features & Benefits
Multiple‑Spring Design: Uniform face loading; compensates for shaft run‑out, wear, and thermal expansion; springs isolated to prevent clogging in slurry service
Balanced Configuration: Reduces heat generation & face wear; suitable for higher pressures
Easy Installation: Pre‑assembled; bi‑directional; no complex alignment
Mixer‑Optimized: Built for LIGHTNIN agitator shaft dynamics; handles moderate run‑out common in mixing equipment
Broad Compatibility: Resists corrosive & abrasive media (gypsum, lime slurry, chemicals)
Applications
Top‑entry & side‑mount mixers (VSF series, etc.)
Flue‑gas desulfurization (FGD) systems
Chemical, pulp & paper, mining, and wastewater treatment
Process agitators for slurries, corrosive fluids, and high‑solid content media
MOR 523 LIGHTNIN Spring Seal is a single‑end, balanced, multiple‑spring mechanical seal engineered as a direct replacement for LIGHTNIN (SPX Flow) agitators/mixers (top‑mount/side‑entry) and compatible chemical process equipment. It features a compact, robust spring‑loaded design optimized for slurry, corrosive, and high‑solid media in industrial mixing applications.
