Mechanical Seals are too often blamed for equipment downtime which is why the Standard Cartridge Seal – ISC2 design includes features that specifically address off-design operation and known causes of mechanical seal failure. Flowserve’s innovative approach to thermal management is a key enabler of long-term seal life and less downtime as the mechanical seals can tolerate dry running events.

Mechanical Seal Failure - equipment downtime

The Standard Cartridge Seal simplifies the entire sealing life-cycle:

• 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: standardise on ISC2

This Standard Cartridge Seal has a wider application coverage than any other comparable Flowserve seal;
– Size range for pusher design extends from 1.000 to 8.000” (25 to 200 mm) and bellows design extends from 1.000 to 3.750” (25 to 95 mm)
– 62 pre-engineered sizes, 400+ designs are available
– 27 additional basic seal components pre-engineered to fill in 0.250 inch increments throughout the product line
– Pre-engineered designs for hundreds of unique pump models and manufacturers spanning the globe
• Custom sleeves, glands, and collars can be engineered to fit special and custom equipment

Key features of the Standard Cartridge Seal – ISC2 include;

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
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 short-term dry run events and batch processes
