ISC2 Series Introduction
ISC2 Series are innovative standard cartridge seals foremost in their improvement of pump availability and MTBR
• New standard of cartridge seals for process pumps provide measurable benefits including:
– Reliability
– Performance
– Safety
– Upset tolerance
– Simplicity
– Versatility
– Serviceability
Simplicity Overview
ISC2 standard cartridge seals simplify the entire sealing lifecycle
• Installation: robust cartridge design
• Selection: single or dual, pusher or bellows
• Handling: lifting hole on large sizes
• Connecting: clearly-marked ports
• Removing: set screws resist galling
• Repairing: complete support at a local QRC
• Inventory: standardize on ISC2
Versatility Overview
ISC2 Series seal the widest range of industrial applications and equipment
• Global-design cartridge mechanical seals for chemical and general purpose applications
• Satisfies key industry specifications:
– ANSI B-73
– EN 12 756
– ISO 3069
– JIS
– API 682 (ISC2-682 seals)
• Fits literally hundreds of pump models in single and dual, pusher and metal bellows configurations
Serviceability Overview
Serviceability comes standard in the ISC2 Series
• ISC2 seals are intentionally designed to be serviced locally
• QRC facilities have the tools and expertise for quality repairs, 24 hours a day, often with same-day service
• Standardized parts reduce inventory requirements and simplify stocking programs
• FSD global network of manufacturing centers and suppliers work to ensure on-time delivery
ISC2 seals have features purposefully developed for multiple industries
• Chemical - corrosion-resistant standard and optional materials of construction; excellent dual seal performance in hazardous and toxic fluids
• Petrochemical - pusher and bellows seal geometries engineered for a broad range of equipment sizes and operating conditions facilitate plant-wide design standardization
• Corn processing - drive mechanisms tolerate high viscosity-driven torque and sticky fluids; high barrier flow rates enhance dual seal cooling
• Pulp & paper - retrofit more packed pumps to significantly reduce leakage and water consumption; springs located outside the process fluid prevent clogging
ISC2 seals are well-suited for all process industries
• Water and Wastewater - simple yet robust single pusher cartridge seals are ideal for cost-effective sealing; hard face options improve solids handling
• Biofuels - economical designs are versatile to multiple service types; cartridge installation is easy and the first step toward reliability
• Mining - pusher seals handle light solids up to 10% by weight with hard-on-hard seal faces; smooth geometry reduces opportunity for erosion
• Power - single seals with an optional circulating device provide economical warm water sealing on condensate and circulation pumps
• Unloading terminals - seal face thermal management survives shortterm dry run events and batch processes
Heritage Comparison
ISC2 Series will run longer, cooler, in tougher conditions, in larger sizes and in more equipment than any heritage standard cartridge seal
• Expanded size range matches complete industry needs
– 1.000 to 8.000” (25 to 200 mm) shaft size for pusher seals
– 1.000 to 3.750” (25 to 95 mm) shaft size for bellows seals
• Large size seals compliment actual pump characteristics
– Robust part geometry utilizes available space in larger pumps
– Greater run-out tolerance
• New and innovative technology enables reliability improvement
– Laboratory and field data demonstrate significant performance improvements
ISC2-682 seals satisfy all API 682 / ISO 21049 Category 1 & 2 design and qualification test requirements
• Built off standard ISC2 components, the wide size range of ISC2-682 seals will fit most API pumps and all enlarged bore ANSI pumps
• ISC2-682 seals are applicable to services within the standard ISC2 operating window and were qualified in water, oil and caustic
– Testing was performed on 1.875” and 3.750” standard ISC2 seals
– Datasheets for all configurations below are available
– Exception lists for ISC2 seals are available
