Belzona offers epoxy and polyurethane repair composites and coatings for repair and protection of pulp and paper equipment susceptible to damage as a result of wear, erosion, corrosion, high temperatures and chemical attack. Our cold-cure materials are specifically designed to provide maintenance solutions for equipment operating in a variety of conditions, whilst reducing downtime, labour costs and eliminating the need for replacement.

Pump repair and protection

Severely damaged pumps in the pulp and paper industry, including liquid vacuum pumps and fan pumps, can be restored to their original profile and protected against the effects of erosion, corrosion, chemical attack and deterioration using Belzona’s range of epoxy repair materials and coatings. cold-cure materials such as Belzona 1221 (Super E-Metal) can be used to repair cracked and holed pumps, providing outstanding chemical resistance.

Our range of coatings such as Belzona 1321 (Ceramic S-Metal) provides long-term erosion and corrosion resistance whilst Belzona 1341 (Supermetalglide) is proven to increase pump efficiency up to 7% on new equipment and up to 20% on refurbished equipment.

Solids handling equipment restoration and protection

Solids handling equipment including screw conveyors, conveyor belts and drive rollers, which are especially susceptible to wear due to the nature of the materials processed, can be repaired and protected using a wide range of metal and rubber repair materials. Durable epoxy repair composites from Belzona 1000 Series such as Belzona 1811 (Ceramic Carbide) are designed to rebuild damaged screw conveyors and provide abrasion resistance for many years.

Belzona rubber repair materials such a Belzona 2111 (D&A Hi-Build Elastomer) and Belzona 2311 (SR Elastomer)can be used for flexible repairs, including worn or torn conveyor belts and drive rollers, without disassembling the equipment. Additionally, by incorporating positive grip systems, our solutions eliminate belt slippage and protect drive rollers from abrasion and corrosion.

Mechanical equipment repair

Mechanical equipment such as shafts and dryer can journals suffering from bearing, vibration, wear and lubrication loss can be repaired using cold repair materials such as Belzona 1111 (Super Metal) and Belzona 1131 (Bearing Metal), which will reduce friction at start up by trapping and holding lubricating oil. Bearing failure can be quickly repaired with fast-curing materials like Belzona 1221 (Super E-Metal), which is specifically designed for emergency repairs.

Evaporator and heat exchanger protection

Belzona offers a variety of epoxy materials for evaporators and heat exchangers damaged by the effects of erosion, corrosion, high temperatures and chemical attack. Our cold-curing repair composites can be used to restore components such as tube sheets, flange faces, water boxes and end covers prone to erosion and corrosion damage, including galvanic corrosion.

High temperature materials such as Belzona 1591 (Ceramic XHT) can be used to rebuild equipment operating at temperatures up to 150°C (302°F). Belzona coatings such as Belzona 1321 (Ceramic S-Metal) are specifically designed to protect evaporators and heat exchangers in continuous immersion from the forces of erosion at temperatures up to 60°C (140°F).

Chipper disks repair

Abrasion resistant materials can be used to repair and protect worn chipper discs, suffering from impact damage, which will improve the pulping process and the quality of manufactured paper. Our solvent-free repair composites such as Belzona 1311 (Ceramic R-Metal) are ideally suited to rebuild worn chipper disc pockets, ensuring satisfactory production of chips.

Our metal repair composites and coatings are suitable for other areas including:

  • Secondary containment areas
  • Structural concrete and steel
  • Pipe leaks
  • Lumber transfer rollers
