MBT™ Metal Bellows High-Temperature Mechanical Seal
UTEX Industries, Inc. has
developed a metal bellows mechanical seal that is corrosion resistant
and designed for high temperature applications. The MBT™ will fit most
popular ANSI and API pumps, without stuffing box modifications. The seal
incorporates a superior nestled ripple bellows design assuring sealing
integrity.
State-of-the-art technology characterizes this
seal throughout. The flexible graphite
secondary seal in the rotating unit remains static and eliminates shaft
or sleeve fretting. The welded bellows core provides 360° face loading.
The special design front hub and face insert minimizes distortion due to
pressure and temperature. The integrally balanced MBT™ Seal remains clean
while running because of the rotating bellows which generates a
centrifugal force to expel abrasives.
