Wood chips and paper pulp are difficult materials to pump due to their viscous and abrasive nature. The papermaking process utilizes several steps that will benefit from the advantages of the EDDY Pump.
Transporting Wood Chips for Pulp Making Pulp Digester Tanks Pulp Bleaching Process Pulp Slurry Transfer
Wood chips and paper pulp are difficult materials to pump due to their viscous and abrasive nature. Centrifugal pumps quickly get worn down and lose their tolerances and suction capabilities. This results in significant downtime and costly spare parts.
The papermaking process utilizes several steps that will benefit from the advantages of the EDDY Pump. During the debarking and chipping process, trees are brought in, debarked and broken down into wood chips. The largest supply of wood chips for the papermaking process comes from the recycled cuttings from sawmills. From there, wood chips are fed by conveyor to a large digester tank where they are cooked in an acidic solution to dissolve the lingin and help separate the plant fibers. This process creates what is called wood-free pulp because the lingin has been dissolved. Finally, additives and dyes are added to the pulp solution, depending on the type of paper being manufactured. All of these steps include abrasive and corrosive slurries that need to be pumped from one location to another.
Transporting Wood Chips and Tree Barkis the first step of the papermaking process. Trees are stripped of their bark, and fed to woodchippers to break them down into small pieces that can be more easily turned to pulp.
Additionally, the abrasive nature of woodchips and bark will quickly destroy the impeller of centrifugal pumps and causes pump failures, costly repairs, and spare parts. Our pump has a high tolerance ultra-recessed rotor that withstands the destructive nature of abrasive pulp slurry.
Pulp Digester Tanksare used to break down the woodchips by removing lingin and separating fibers. This process incorporates abrasive slurries in addition to strong acids that are highly corrosive. These materials are difficult to pump and will quickly wear down pumps with critical tolerances.
The EDDY Pump does not require critical tolerances between the rotor and the volute, making the EDDY Pump the perfect solution for abrasive and corrosive paper and pulp applications. Moreover, the EDDY Pump will run continuously with significantly less spare parts needed and saving papermaking and production plants millions in total ownership cost over the life of the pumps.
ThePulp Bleaching Processinvolves moving the freshly separated pulp to large tanks for the injection of bleach, fillers, dyes and other materials required for the type of paper being produced.This process also removes any residual traces of lingin from the pulp. From here, the pulp is dried for use in the next step of the papermaking process.
Some industries, such as sugar production, produce large quantities of by-products, in this case,bagasse. Bagasse is the term for the leftover, crushed sugar cane material that is left behind after the sugar juice extraction process. This bagasse is used in some countries as pulp for papermaking.
Pulp Slurry Transferis a constant process in the papermaking industry. At several stages of papermaking, pulp slurry is needed to be transported from one location to another. This slurry is often extremely viscous, heavy and abrasive which requires a pump built to withstand clogs, high solids content and corrosive materials.
EDDY Pump’s open rotor design promotes the passage of large solids such as woodchips, rocks, pulp and other fibrous material that easily clog centrifugal pumps.

Easier to install and maintain, the horizontal slurry pump, a type of dredge pump, allows for quick access to pump components, making repair jobs straightforward. During repair jobs, pumps are completely disassembled for thorough inspection. All components are carefully inspected, and any parts not meeting standards are replaced. After reassembly, the pump is tested to ensure reliable performance. These steps help extend the service life of the hydraulic pump and maintain equipment reliability. EDDY Pump can also provide dredging project managers to oversee sediment projects and remediation projects, ensuring that all aspects of the dredging project are managed efficiently and in compliance with environmental regulations.
Requires more room, due to its larger footprint compared to vertical Implementing best management practices and evaluating management alternatives are essential for effective material management in any dredging project.
Less smaller footprint, allowing the dredge pump to be implemented in hard to reach jobs More versatile, can be cable hung straight down and inserted directly into medium to pump target material. The vertical slurry pump can also be used in mechanical dredging operations where minimal water addition is required. The vertical slurry pump is typically situated within the excavator or dredging system so that it is optimally positioned for efficient material handling and performance. More difficult to repair and tougher maintenance
The EDDY Pump can be deployed in various configurations to optimize the paper & pulp process. Some of the ideal deployments for paper and pulp pumping are Submersible,EDDY Slurry Pump, Flooded Suction, Self-Priming Pump
The workhorse behind all of our pump and dredge products. The EDDY Slurry pump is a non-clogging pump capable of pumping high viscosity, high specific gravity, high abrasives, and highly corrosive materials. The EDDY Pump’s open rotor design allows the passage of solids of up to 12 inches and capable of pumping 30-70% solids by volume. The EDDY Pump is highly versatile and able to be deployed for a wide variety of heavy duty applications.
Hydraulic dredging has versatile applications in the gold mining industry, facilitating underwater gold extraction, sediment and tailings removal, pond dredging, reclamation projects, and environmental remediation. Its efficiency in handling underwater deposits, versatility, and environmental friendliness make hydraulic dredging a valuable tool for gold mining companies seeking to optimize their extraction processes and minimize ecological impact.
Most EDDY Pumps are submersible, with a self-priming unit, the pump and power unit are not submerged. The suction house goes into the slurry and the unit acts like a super-sized wet vacuum.This type of pump can remove air on its own and continue operation without assistance, making it perfect for mounting on a trailer that can be wheeled from location to location. Becuase the pump is not submerged, both the operation and maintenance ofself-priming slurry pumpsare economical and relatively easy.
