Type 2

Manufacturer: John Crane

Multi purpose Non pusher Elastomer Bellows Seal

The Type 2 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.

• 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.
