Chemineer™ ChemSeal™ Top Entering Mixer Seal

ChemSeal is a true Chemineer
mixer seal designed for demanding
top entry agitator applications.
Safe and Reliable Operation
• Double balanced seal design keeps
seal faces closed during a pressure
reversal caused by process
upset or failure of barrier system,
preventing seal failure, containing
vessel contents, and improving
operator and plant safety
• Permanently installed above the
tank drop collar design securely
holds the shaft during seal change
and improves operator safety by
eliminating “on the fly” installation
of shaft support, prevents the
shaft from falling into the vessel,
and eliminates the need for vessel
entry or overhead cranes to
support the shaft

Simple Maintenance and Fast
Replacement
• Industry leading swing-out seal
change out procedure with
drop collar is simple and can be
completed in 30 to 60 minutes,
providing increased process
uptime
• True cartridge design allows
for removal, inspection and
replacement of worn seals
quickly and easily
• Mixer seal design and heavy duty
gearbox bearings eliminate need
for a seal bearing and associated
installation and maintenance costs
• Provision for jacking screws and
setting clips storage is provided
to aid in seal removal and future
setting of the seal

Application Versatility
• Bidirectional rotation enhances
process and operational flexibility
• Designed for a wide range
of agitator models to allow
ChemSeal to be the common
plant standard
• Throttle bushing option is
available for clean flush below seal
• Debris well option available to
eliminate process contamination

Superior Performance
• Available in either single or
double configurations, the
ChemSeal provides outstanding
seal performance and safety
• ChemSeal is designed specifically
for agitator duties where shaft
movements are larger, speeds
are slower and conditions more
variable than those encountered
by pump seals
• Balanced seal design reduces seal
face wear rate and increases the
pressure capability by reducing
the seal contact pressure as the
process pressure fluctuates
• Dual sleeve to shaft o-rings with
heavy cross sections make the
seals more tolerant of shaft
deflections inherent in agitator
applications

Troubleshooting and
Replacement Parts Assistance
• Our service center is available
24 hours a day to diagnose and
correct sealing problems
• Factory trained technicians
available for in-plant help with
installation, operation and
maintenance questions
• tReplacement parts are readily
available to increase uptime
and reduce customer inventory
requirements
