Type 2 and 2M
Elastomer Bellows Seals
Applications
'= For confined space requirements
‘and limited gland depths in pumps,
mixers, blenders, agitators,
compressors and other rotary shat
equipment.
' For pulp and paper, petrochemical,
food processing, wastewater
treatment and other demanding
applications.
‘Type? seals are suitable for a wide
range of service conditions: from
water and steam to chemicals and
‘corrosive materials,
Operating Conditions
= Temperature:
10°C to +200°O/
=d0°F to +390°F
Depending on materials used
© Pressure:
Fpped, = Upto 28 bar o/400 psig
‘2M —Up to 32 bar 3/485 psig
m/s /2500 fom
Design Features/Benefits
elf-Aligning
\utoratic adjustment compensates for
‘abnormal shat end play, run out,
primary sealing wear, and machinery
{glerances, leading to improved service
fe.
Mechanical Drive
‘The drive ring's notch design eliminates
Qver-stressing of the elastomer bellows,
Slppageis aiminatod, protecting the
shaft and sleeve from wear,
Non-Clogging, Single Coll Spring
Provides greater dependability than
‘multiple spring designs, Willnatrun foul
due to fuld contact,
‘Short Working Height
‘Thesingle spring fits over the sealhoad.
Special
Balancing
Forhigher pressure applications,
‘greater operating speeds and lower
Wear
Completely Field Repairable
‘Type? and 2M seals can be repaired in
the eld toriinimisereplacement costs,
downtime and lost revenue.
