Applications of Peristaltic Pumps in the Pulp and Paper Industry

Overview

The pulp and paper industry produces paper and paperboard products from raw materials like wood and recycled paper. Key stages include pulping (chemical or mechanical), bleaching, papermaking, finishing/coating, and conversion/printing. The industry faces environmental challenges but is adapting with sustainable practices and alternative fibers.

Depending on specific features and functions, GAO Tek’s Peristaltic pumps are sometimes referred to as tube pumps, hose pumps, roller pumps, squeeze pumps, flexing pumps, wave pumps, positive displacement pumps, tubing pumps, roller-tube pumps, finger pumps, fluidic pumps, flexure pumps, soft tube pumps, elastomeric pumps, and cavity pumps.

Furthermore, GAO Tek’s peristaltic pumps are further grouped into: Anti-interferences, Benchtops, Data loggings, Multi-channels, Outdoors, Rugged, Temperature controls, and Touch screens.

GAO Tek’s Peristaltic pumps have the following applications in the pulp and paper industry:

Chemical Dosing Precision: GAO Tek’s peristaltic pumps play a critical role in the pulp and paper industry by precisely dosing chemicals required in various stages of paper production. These pumps accurately meter and inject bleaching agents, dyes, sizing agents, and additives into the manufacturing process. Their precise control ensures optimal chemical distribution, contributing to the quality and efficiency of paper manufacturing while minimizing waste and environmental impact.
Efficient Handling of Pulp Slurries: Within paper mills, peristaltic pumps are essential for transferring pulp slurries and wastewater. They effectively handle high-viscosity fluids and slurries containing abrasive particles without clogging or damage. GAO’s peristaltic pumps facilitate the transfer of pulp between different stages of the papermaking process, such as from pulping to refining or from stock preparation to the paper machine, ensuring smooth operations throughout.
Recycling Loop Support: GAO Tek’s peristaltic pumps are integral to the recycling loop of the pulp and paper industry, facilitating the transfer of recycled paper pulp slurry during repulping and deinking processes. Used paper is transformed into pulp for reuse in paper production. The gentle pumping action of GAO’s peristaltic pumps helps maintain the integrity of recycled fibers, minimizing energy consumption and maintenance requirements in the recycling process.

Systems in the Pulp and Paper Industry Utilizing Peristaltic Pumps

Here are some popular systems in the pulp and paper industry using peristaltic pumps:

Chemical Dosing System:

Bleaching Agent Dosing: Peristaltic pumps are employed to precisely dose bleaching agents such as chlorine dioxide or hydrogen peroxide into the pulp at specific stages of the bleaching process to achieve desired brightness levels in the final paper product.
pH Adjustment: Peristaltic pumps accurately dose acid or alkali solutions to adjust the pH of pulp slurries during various stages of the papermaking process, ensuring optimal conditions for chemical reactions and fiber retention.

Pulp Transfer and Stock Preparation:

Refiner Feeding: Peristaltic pumps transfer pulp slurry from the pulping stage to the refining stage by pumping the pulp through pipelines to refiners, where the fibers are mechanically treated to achieve desired properties such as strength and smoothness.
Stock Chest Circulation: Peristaltic pumps circulate pulp slurries within stock chests to maintain consistent pulp quality and ensure uniform fiber distribution before feeding the pulp to the paper machine.

Deinking System:

Ink Slurry Transfer: Peristaltic pumps facilitate the transfer of ink-laden pulp slurry from the deinking pulpers to flotation cells or washing stages, where ink particles are separated from the fibers through froth flotation or washing processes.
Chemical Additive Dosing: Peristaltic pumps accurately dose chemicals such as surfactants and dispersants into the deinking process to enhance ink detachment from fibers and improve ink removal efficiency.

Waste Treatment and Effluent Management:

Chemical Flocculant Dosing: Peristaltic pumps dose flocculants or coagulants into wastewater streams to promote the aggregation and settling of suspended solids, facilitating solid-liquid separation in clarifiers or sedimentation tanks.
Sludge Dewatering: Peristaltic pumps transfer thickened sludge from dewatering equipment such as belt presses or centrifuges to sludge drying beds or incinerators for further treatment or disposal.

Additive Injection and Coating Systems:

Surface Sizing Additive Injection: Peristaltic pumps inject surface sizing agents such as starch solutions or synthetic polymers onto the paper surface to improve surface strength, smoothness, and ink receptivity.
Coating Color Preparation: Peristaltic pumps accurately dispense pigments, binders, and additives into coating color formulations for coated paper products, ensuring consistent color coverage and coating properties on the paper surface.

Colorant and Pigment Dispensing:

Ink Formulation: Peristaltic pumps meter colorants, pigments, solvents, and additives into ink formulations for various printing applications, including offset, flexographic, and digital printing processes, ensuring precise color matching and consistency.
Toner Manufacturing: Peristaltic pumps dose toner components such as pigment particles, polymer resins, and magnetic additives into toner manufacturing processes for laser printers and photocopiers, ensuring uniform toner particle size and distribution.

Case Studies of Peristaltic Pumps in the Environmental Monitoring Industry

Peristaltic pumps are sometimes called tube pumps, hose pumps, roller pumps, squeeze pumps, flexing pumps, wave pumps, positive displacement pumps, tubing pumps, roller-tube pumps, finger pumps, fluidic pumps, flexure pumps, soft tube pumps, elastomeric pumps, and cavity pumps.

Here are some practical examples of using peristaltic pumps in the pulp and paper industry:

In the Northeast region of the U.S., a paper mill in Maine implemented peristaltic pumps in its chemical dosing system to precisely control the addition of bleaching agents during the paper whitening process. By integrating peristaltic pumps with advanced process control software, the mill achieved significant improvements in paper brightness and quality, while reducing chemical waste and operating costs.

In the Midwest region, a paper manufacturing facility in Wisconsin upgraded its pulp transfer system with peristaltic pumps to improve reliability and efficiency. By replacing traditional pumps with peristaltic technology, the mill experienced reduced downtime due to pump failures and improved pulp transfer rates, resulting in enhanced productivity and operational performance.

In the South, a paper mill in Georgia optimized its waste treatment and effluent management system by incorporating peristaltic pumps for chemical dosing and sludge dewatering. The implementation of peristaltic pumps enabled the mill to achieve more effective wastewater treatment, meet stringent environmental regulations, and minimize environmental impact while maintaining operational flexibility.

A paper recycling facility in Oregon enhanced its deinking process by integrating peristaltic pumps for ink slurry transfer and chemical additive dosing. The use of peristaltic pumps improved ink removal efficiency, reduced fiber loss, and enhanced the quality of recycled pulp, enabling the facility to produce high-quality recycled paper products while maximizing resource utilization.

In Canada, a pulp and paper mill in British Columbia upgraded its additive injection and coating systems with peristaltic pumps to enhance product quality and consistency. By implementing peristaltic pumps for precise additive dosing and coating color preparation, the mill achieved superior control over paper properties, reduced material waste, and increased customer satisfaction with the final paper products.
