Reducing Downtime from Seal and Filtration Failures in Paper Mills

Paper mills combine wet, fibrous stock handling with high-pressure steam systems in the same facility — two very different sealing environments that are easy to under-specify if a plant standardises on a single packing grade for simplicity.

Pulping and stock preparation seals

Pulp stock carries fibre and grit that wears ordinary packing quickly, similar to the abrasive duty seen in sugar-mill crushers. Aramid Gland Packing resists this abrasion far better than standard yarns on stock pumps and pulpers.

Steam and boiler-side sealing

Graphite Gland Packing covers steam and boiler-feed duty at 450°C+, the same standard used across power-plant steam systems.

Stock and process filtration

Rotary Filter Cloth handles stock thickening and washing filtration, selected to match the fibre consistency of the specific process stage.

Felt and cushioning components

Wool Felt and Polyester Felt cover general oil wicking, cushioning and vibration damping on mill machinery — distinct from specialised paper-machine press felts, but relevant across general mill equipment.

Frequently asked questions

Why does our pulper packing wear out faster than the manual predicts? Almost always fibre and grit in the stock attacking a packing grade not built for abrasion — aramid packing addresses this directly.

Can one filter cloth spec cover both thickening and washing stages? Usually not optimally — each stage has different consistency and fibre characteristics that benefit from a matched weave.

Tell us the stage — pulping, stock prep, or steam — and we’ll confirm the right packing or filter media.
