صناعة اللب والورق

The pulp & paper industry involves complex processes such as pulping, bleaching, coloring, coating, and drying. Throughout production, various liquids,including strong alkalis, bleaching agents, and pulp suspensions,must be continuously and safely transferred. These fluid often feature high corrosiveness, fiber content, and solid residues, posing challenges like pipe clogging, seal leakage, and pump corrosion. Reliable, corrosion-resistant, and clog-proof pumps are therefore essential to maintain stable production and reduce downtime.

Changyu offers tailored solutions with fluorinated lining pumps for corrosive fluid and vertical submersible Pumps for fibrous slurries—plus custom-engineered designs to meet specific pulp & paper industry process needs.

Custom Pumps for the Pulp & Paper Industry

Changyu develops industry-specific pump systems made for pulp & paper applications.
  • مضخة طرد مركزي ذاتية الطرد المركزي المبطنة بالفلور FZB

    Highly Corrosive Fluids

    نوع المضخة الموصى به: Fluoroplastic-lined pump
    السبب: The pump body is internally lined with fluoroplastic materials such as polytetrafluoroethylene (PTFE), offering exceptional corrosion resistance. It withstands the corrosive effects of harsh fluids including concentrated alkalis and strong oxidising bleaching solutions.
  • مضخة غاطسة عمودية غاطسة من الفولاذ المقاوم للصدأ من سلسلة FY

    Fibrous and Slurry Fluids

    نوع المضخة الموصى به: مضخة غاطسة عمودية
    السبب:
    The pump body may be directly immersed in the medium during operation, thereby saving installation space and enabling the effective conveyance of wastewater, pulp, and other fluids containing fibrous residues.

Application in Pulp & Paper Industry

The pulp & paper industry encompasses complex liquid handling at every stage, from pulping and bleaching to coating and wastewater treatment. Conveyed fluids frequently contain fibres, solids and potent chemicals, leading to blockages, corrosion and wear issues. Pumps operating in such environments must deliver consistent, reliable performance under harsh conditions to ensure efficient material transfer and production stability.

Changyu provides bespoke pump solutions for the pulp & paper industry, integrating anti-clogging, wear-resistant and corrosion-resistant properties to enable long-term, trouble-free operation of equipment.
