Key Benefits

    • Reliable operation
    • No droplegs
    • Low maintenance requirements
    • Tolerable to high feed consistencies
    • High turndown capabilities
Reliable operation
The GDX gravity drum decker is insensitive to variations in feed flow or feed consistency, and it works without instrumentation or regular operator attention.

The pulp discharge consistency is normally in the range of 4 to 5% solids, depending on the pulp freeness and feed consistency.

No droplegs
The GDX operates without any need for dropleg or other vacuum sources.

The driving force for the dewatering is the static pressure difference between the liquid level in the vat and the liquid level in the drum.

Low maintenance requirements
The gravity drum has very few wear parts. The fabric has a long life time since there is no contact with other surfaces (no couch roll). The drum seal is easily replaced if worn.
