| Applications: |
|
For use with extremely corrosive chemicals, including concentrated
Acids and salts, strong oxidizing agents
and chemically active compounds.
Suitable for use with abrasive contaminated and corrosive fluids
and for Slurries, sewage water, viscous
liquids.
By choosing suitable component material the seals can be adapted
to operate with a wide range of liquid
and operating conditions.
|
| Operating Limits |
|
Size range: 1” to 6” (10mm to 200 mm)
Temperature: -50c° to + 120c°/-50 F° to 250 F° depending
on the material used.
Pressure: 13 bar g/185 psig.
Speed: Up to 3000 RPM according to seal size and working
pressure.

| Versatile Constructions/Options
|
|
Type DB-TB
All surfaces contacting the liquid being sealed are made of chemically
inert materials. Metallic components are located outside the seal
chambers and isolated from the liquid area.
|
| Design features: |
External Mounting
Mounted outside of the seal chambers with only the internal surfaces
of the bellows and face in contact with the liquid.
Flexible PTFE Bellows
Maximum corrosion resistance. Eliminates the possibilities of
seal face misalignment. Compensates for shaft run-out to promote
long life operation.
Mechanical Drive
Half clamps secure the bellows tail to the shaft and eliminates
galling and premature shaft wear.
Replaceable Seal Face
These seals have replaceable seal face insert, so that different
face materials can be used to handle wide range of corrosive and
abrasive fluids.
Field Repairable
Reduces inventory requirements. Seals can be repaired easily on
site or at any Daybreak's seal repair centers, and/or converted
to various seal face combinations.
