Pulp and Paper Industry Pumps

The pulp and paper industry is a common industrial scenario with high abrasion, high corrosion, and continuous multi-condition operation. In processes such as pulping, bleaching, chemical recovery, and wastewater treatment, pumps are required to continuously transfer high-concentration fiber slurry, corrosive chemical liquids, and high-temperature media. If the pump selection is improper, problems such as blockage, corrosion leakage, frequent maintenance, and even system shutdown may occur.

Changyu Pump has over 20 years of experience in the industrial pumping industry. Through proper pump type selection, material selection, and customized structural optimization, we can solve common problems in the pulp and paper industry such as corrosion resistance, wear resistance, and pulp slurry pumping, while ensuring stable and continuous operation.
CYH alloy centrifugal pumps / open impeller slurry pumps, UHMWPE lined corrosion-resistant centrifugal pumps, and CYC / CYQ bơm truyền động từ tínhs are the pump models we commonly supply for the pulp and paper industry.

Custom Pumps for the Pulp & Paper Industry

Changyu develops industry-specific pump systems made for pulp & paper applications.
  • Bơm bùn ngang hóa chất series UHB2

    Pulp Slurry Transfer Application

    Loại bơm được khuyến nghị: Chemical Horizontal Slurry Pump
    Lý do: This pump is specially designed and manufactured as a single-stage, single-suction cantilever chemical pump for transferring media containing corrosive substances and solid particles. The pump casing is made of imported highly wear-resistant and corrosion-resistant UHMWPE material, and it adopts a semi-open impeller design, which helps reduce fiber blockage and impeller wear risks during pulp slurry pumping.
  • Bơm ly tâm chịu ăn mòn bằng thép không gỉ CYH

    Bleaching Liquid Circulation Application

    Loại bơm được khuyến nghị: CYH Series Stainless Steel Chemical Centrifugal Pump
    Lý do:     This pump is designed to allow different material selections according to the characteristics of the medium. The stainless steel pump casing is one of the most commonly used materials. Combined with our self-developed sealing system, it enables stable and efficient circulation pumping, and supports the transfer of medium-temperature to high-temperature, generally corrosive media. The pump offers flexible customization and is suitable for a wide range of operating conditions.
  • Bơm chống ăn mòn

    Black Liquor / White Liquor Transfer Application

    Loại bơm được khuyến nghị: Bơm chống ăn mòn loại UHB bằng nhựa polyethylene mật độ cực cao (UHMWPE)
    Lý do: This pump uses ultra-high molecular weight polyethylene (UHMWPE) lining as the main material for all wetted parts, making it well suited for strongly corrosive and highly alkaline media. The wear resistance of this material is 7–10 times that of stainless steel, which also gives the pump stronger abrasion resistance. It is capable of long-term pumping of corrosive media containing solid particles.
  • Bơm từ tính thép không gỉ chịu lực cao series CYC

    Chlorine Dioxide and Other Hazardous Media Transfer Application

    Loại bơm được khuyến nghị: CYC Series Heavy Duty Stainless Steel Magnetic Drive Pump
    Lý do:     This magnetic pump adopts a magnetic coupling, sealless design, which enables a leak-free pumping solution. It is made entirely of stainless steel, and the wetted parts exhibit excellent corrosion resistance when handling corrosive and volatile chemical media. The pump also complies with the API-685 design standard, allowing it to withstand certain pipeline pressure fluctuations while maintaining stable pumping performance.
