Innovative features to succeed in general process pump applications
• Robust silicon carbide and carbon face cross
sections for increased reliability
• Silicon carbide mating rings are held in
compression and are protected for reliable
equipment start-up
• Homogenous carbon designs for the pusher
configuration results in stable performance
• Bellows units constructed of all Alloy C-276
enhances chemical compatibility resulting
in longer seal life
• The robust gdm drive flat mechanism enhances
reliability by eliminating the need for drive pins
and drive notches with resulting stress risers.
• Springs are isolated from the process fluid
reducing stress corrosion
• Dual seals are double balanced to provide both
pressurized and non-pressurized dual seal
options increasing equipment dependability.
• A unique pumping feature, standard on all dual
seals, is more effective than conventional dual
seal pumping features resulting in cooler seal
operation and enhanced seal
