Metal Bellow Seals
|
 |
| Type DB-MB Metal Bellow Seals |
|
| Applications: |
|
For use with high temperature oils, chemicals, Petrochemicals
and refinery processing DIN 24960 and
ANSI B73 pump applications.
Suitable for process services requiring corrosion resistance.
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: -75c° to + 430c°/-100 F° to 800 F° depending
on the material used.
Pressure: 35 bar g/500 psig.
Speed: Up to 3000 RPM according to seal size and working
pressure.

| Versatile Constructions/Options
|
|
Type DB-MB
Edge welded Metal bellow seals are constructed by series of stainless
steel diaphragm together to from a bellow unit. The bellow unit
eliminates the need of springs and provides flexibility to the seal
in addition compensates for seal face wear.

| Design features: |
Optimum Designed Bellows
Provides superior performance in the most difficult process services.
Daybreak Graphoil Secondary Seal
Pure and flexible Graphite packing allows seal to be used in extreme
temperature conditions.
Tilted Bellows Angle
Angle of bellow section is tilted at the inner diameter weld to
relive stress concentration and provide longer seal life. Double
nested configuration improves flexibility and reduces stresses.
Large Grub Screws and Cap Screws
Ease of installation with strength. Provides firm grip on the
rotating element.
Self-Cleaning Design
Rotating bellows throw off suspended solids that clog the spring
type seals. This self-cleaning action eliminates the need of external
flushing, filters or cyclone separator and their associated cost.
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.
