SEPCO Synthetic Packing

ML 402 General Service Packing Construction: Multi-Lok Braid Features: Non-asbestos fibers treated with a specially formulated blend of lubricants having a saxoline base. Treatment: Each strand is individually coated with graphite and the braid is surface coated with graphite. Equipment: General service on rotary and reciprocating equipment. Recommended For: Mild acids, alkalines, steam, brine, oil. Limitations: Shaft speeds to 1885 FPM; temperatures to 450F/232C; pH range 4 - 10. Remarks: Good general service packing. The lubrication formulation makes the extra difference. The ductile nature of the lubricant prevents wicking and provides superior seal ability. Style 402: Same as ML 402 except it is square braided. ML 2225 General Service, PTFE/Synthetic Packing Construction: Multi-Lok Braid Features: Yarns are coated in PTFE suspensoid. This system of impregnation assures even distribution of the PTFE. The fibers are saturated and sealed with the PTFE particles, protecting the fibers from chemical action. Surface Treatment: A surface coating of PTFE is applied after braiding. To assure good break-in characteristics, a special high temperature synthetic lubricant is added. Equipment: General service on rotary and reciprocating pumps, agitators. Recommended For: Caustics, mild acids, difficult chemicals, air, gasses, solvents, oils, general chemical plant applications. Limitations: Shaft Speeds to 1885 FPM; temperatures to 500F/260C; pH range 3 - 11. Remarks: Our proprietary PTFE dispersion system provides greater penetration and more thorough dissemination of the inert PTFE. Our finest general service packing. Style 2225: Same as ML 2225 except it is square braided. ML 2225A Packing Construction: Multi-Lok Braid Features: Yarns are dipped in PTFE suspensoid. This system of impregnation assures even distribution of the PTFE. The fibers are saturated and sealed with the PTFE particles, protecting the fibers from chemical action. The PTFE provides the packing with a greater degree of chemical inertness, lower coefficient of friction and prevents penetration of chemical fluids. The corner tracks are made from an Aramid filament yarn to reduce extrusion and increase pressure and strength characteristics. Surface Treatment: A surface coating of PTFE is applied after braiding. To assure good break-in characteristics, a special high temperature synthetic lubricant is added. Equipment: General service, rotating and reciprocating pumps, agitators. Recommended For: Caustics, mild acids, difficult chemicals, air, gases, solvents, oils, general plant applications. Limitations: Shaft speeds to 1885 FPM; temperatures to 500F/260C; pH range 3 - 11. Remarks: Our proprietary PTFE dispersion system provides greater penetration and more thorough dissemination of the inert PTFE. Our fines general service packing. ML 2250 PTFE/Synthetic Packing Same as ML 2225 except no break-in fluid. Equipment: Valves, flanges, expansion joints. Recommended For: Valve service and static gasket applications, caustics and mild acids. Remarks: Use wherever break-in oil is undesirable. Style 2250: Same as ML 2250 except it is square braided. ML 2400 High Performance Service Packing Construction: Multi-Lok Braid Features: A Multi-Lok braided with SEPCO's unique lubrication process that transforms each individual fiber into a reservoir of lubrication for longer packing life. An excellent high performance alternative. Treatment: Proprietary non-petroleum lubricant containing no sulphur, silicone or wax. Equipment: Rotating and reciprocatinf pumps, washer journals, liquor pumps, refiners, digesters and many other uses. Recommended For: General service applications where graphite may not be acceptable: steam, water, acid, chemical and solvent applications, multi-use in chemical plants and pulp and paper mills. Limitations: Shaft speeds to 1800 FPM; temperatures to 500F/260C; pH range 1 - 13 (except concentrated or hot sulfuric or nitric acid.)
