Features

• The drive band’s “dent and groove” design eliminates overstressing of the elastomer bellows to prevent bellows slip and protect the shaft and sleeve from wear
• Non-clogging, single-coil spring provides greater dependability than multiple spring designs and will not foul due to fluid contact
• Flexible elastomer bellows automatically compensates for abnormal shaft-end play, run-out, primary ring wear and equipment tolerances
• Self-aligning unit automatically adjusts for shaft end play and run-out
• Eliminates potential shaft fretting damage between the seal and shaft
• Positive mechanical drive protects the elastomer bellows from overstressing
• Single coil spring improves tolerance to clogging
• Simple to fit and field repairable
