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.

TEMPERATURE LIMITS	-40°F to 400°F/-40°C to 205°C (depending on materials used)
PRESSURE LIMITS	150 psi(g)/10 bar(g)
SPEED LIMITS	Up to 2500fpm/13m/s, depending on configuration and shaft size

Recommended Applications

• Process pumps
• Other rotating equipment
