Why ISC Seal? • Provide the highest value standard cartridge seal line for ANSI and general pump applications. • Maximum interchangeability at the lowest cost to the end user and FSD. • Provide the highest value product for the extremely price sensitive markets where more emphasis is placed on initial cost than Life-Cost Value. • Holistic approach in providing single and dual seal arrangements with pusher and bellows options.

• Allows application of the correct configuration to each application. • Increased use of common parts allows for mass manufacture of components resulting in lower manufacturing and inventory costs.

ISC Technical Features Stationary Pusher Seal Springs are held Stationary avoiding back and forth motion of the Dynamic O-ring. Hence NO Shaft Fretting. Prevents Face Oscillation. Allows true self alignment.

Canned Rotor Design Silicon Carbide rotor is captured in the sleeve “Can” thereby protecting the seal faces during installation. Fluid Sealing Division

ISC Technical Features Secondary Dynamic Sealing Element Design Secondary sealing element rides on metal surface, increasing reliability.

Thick Carbon and Carbide Cross-sections Silicon Carbide Mating Ring and Carbon Primary Rings have beefy cross sections to handle installations and dynamic process upsets. Fluid Sealing Division

ISC Technical Features Robust Drive Arrangement Drive flats are used to transmit drive to the rotating seal face. Drive pins, notches and resulting stress raisers have been avoided to increase seal reliability.

Springs are Completely Isolated Alloy C-276 springs are completely isolated from the process fluid to minimize stress corrosion. Fluid Sealing Division

ISC - Features / Benefits •

Thick carbide and carbon cross sections : Thin cross sections of carbon and carbide parts are very susceptible to premature fracture. Special care was exercised during the design phase to beef up the cross sections for these parts resulting in increased reliability.

•

Silicon carbide mating rings are held in compression and are protected resulting in increased reliability, especially start-up reliability.

•

Homogenous carbon designs for the pusher configuration results in no performance variations from cyclical temperatures.

•

Design eliminates the use of drive pins, drive notches, stress raisers, etc. resulting in increased reliability.

•

Compression springs are isolated from the process fluid reducing stress corrosion. Fluid Sealing Division

ISC - Features / Benefits • Dual seals are double balanced to provide both pressurized and nonpressurized dual seal options. • Care has been exercised to place the secondary sealing points on I.D. grooves so that Teflon O-rings can be used to reduce the need for perfluoroelastomers and provide lower cost seals. • A unique pumping feature is 50% more effective than conventional standard dual seal pumping features allowing cool operating seals and enhanced MTBF of the seal. • All Alloy C-276 bellows units increase the corrosion resistance of the bellows unit resulting in enhanced reliability of the sealing device.
