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
    An”O” 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.
