| Applications: |
|
For pulp and paper, petrochemicals, food processing, wastewater
treatment and other demanding applications.
Suitable for use with abrasive contaminated and corrosive fluids,
for slurries, sludge and effluents with
solid presence.
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: 3/8 to 6 (10mm to 200 mm)
Temperature: -40c° to + 205c°/-40 F° to 400 F° depending
on the material used.
Pressure: Type DB-LP-Up to 17 bar g/247 psig, Type DB-LM
Up to 62 bar g/900 psig.
Speed: Up to 6000 RPM according to seal size and working
pressure.

| Versatile Constructions/Options
|
|
Type DB-LP
AnO ring or U pack-sealing member available
in TTV, Rubber and Flexible Grphite, creats positive sealing along
with the rotating shaft.
Type DB-LM
Typical Duck Bellow made of suitable rubber. The tail end of the
duck bellow is held tight to the shaft to form a static sealing
joint. As the seal face wear occurs, the bellow convolution extends
the seal face to compensate the wear.
|
| Design features: |
Self-Aligning Design
Automatic adjustment compensates for abnormal shaft end play,
run0out, and primary sealing wear and machinery tolerances leading
to improved seal life.
Compact Design
Full convolution elastometric Bellows designed for confined spaces
and limited gland depths. Self-aligning feature compensates for
shaft end play and run-out.
Single Coil Spring
The single coil spring designs ensure the safe pass thru of contamination
or solids presence in the process liquid. On clog design which
allows the usage of seal in wide range of slurries and sludge
type applications.
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.
