Mechanical Drive
To absorb both breakout and running torque, the seals are 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.
Self-Aligning Capability
Automatic adjustment compensates for abnormal shaft end play runout, 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. Will not run foul due to fluid contact.
Low Drive Torque
Improves performance and reliability.
