Multi-purpose Non-pusher Elastomer Bellows Seal is2
The is2 mechanical seal is available in single, double and balanced arrangements. An outside-mounted spring results in a compact working height that enables it to fit very short stuffing boxes.
Product Description is2
iseal is2 Elastomer Bellows Seals are specified in more original equipment than any other seal from any other manufacturer. With the highest success rate of any seal of their type, they are suitable for a wide range of service conditions, including water, refrigeration, oils and chemicals.
is2B is a balanced seal used in higher pressure applications,offering greater operating speeds and reduced face wear
Fits equipment with confined space requirements and limited seal chamber depths in pumps, mixers, blenders, agitators, compressors and other rotary shaft equipment
For pulp and paper, food processing, water, wastewater, refrigeration, chemical processing and other demanding applications

- California Residents: PROPOSITION 65 WARNING
- Fits equipment with confined space requirements and limited seal chamber depths in pumps, mixers, blenders, agitators, compressors and other rotary shaft equipment.
- To absorb both breakout and running torque, the seal is designed with a drive band and drive notches that eliminate overstressing of bellows.
- Slippage is eliminated, protecting the shaft and sleeve from wear and scoring.
- Automatic adjustment compensates for abnormal shaft-end play and run-out, primary ring wear and equipment tolerances. Axial and radial shaft movement is compensated for with uniform spring pressure.
- Special balancing allows for higher pressure applications, greater operating speeds and lower wear.
- Non-clogging, single-coil spring allows for greater dependability than multiple spring designs, and it will not run foul due to fluid contact.
