Pulp and Paper Market Pumping Operations

Wood chipping / Debarking

Making paper involves many processes that require different types of pumps for mixing, metering, and pumping various abrasive materials and chemicals. Pulp production starts with raw materials, typically trees, that must be cut into logs before going through a debarking and chipping process. Pumps that move this material for further processing in the pulp production cycle must withstand the harsh abrasiveness in the debarking and chipping process such as self-priming and submersible slurry pumps.

De-Inking

Pumps must support the chemical and mechanical pulp line as corrosive chemicals like sodium hydrosulfite, sulphuric acid, sodium hydroxide, sodium silicate, and various soaps are used for the de-inking stage in paper mills. Flotation tanks collect ink particles allowing the pulp to sink to the bottom to be pumped out.

Stock Preparation

Stock preparation occurs after the paper mill receives the pulp in a continuous feeding solution for continual production. Cellulose fibers and pulp require the adding of fillers while suspended in water for fiber bonding.
Various pumps support the de-inking and stock preparation stages in a paper mill including rotary vane, gear pumps, self-priming, flooded suction, and submersible pumps.

Wet End Chemical Preparation

Several additives are required in the paper production process including dyes, starches, retention aids, fillers, brighteners, calcium carbonate, polyaluminum chloride, and many other chemicals that must be metered and pumped into the stock. Many types of pumps such as submersible slurry pumps, self-priming, rotary vane, lobe, and gear pumps support the wet end chemicals preparation process in paper mills.

Starch Preparation

Cationic starches provide many benefits such as improving mechanical strength, retention of fillers, quicker drainage, and reduction of wastewater pollution. The starches are cooked in a solution, metered, and pumped continually into the paper stock mix to primarily provide strength and retention in papermaking. Pumps in this process must perform at high temperatures typically over 100°C and include self-priming and flooded suction pumps.

Wastewater and dewatering

Many unusable byproducts are inevitably created during the papermaking process and include flocculants, effluents, and sludge that must be pumped away and removed from the plant. This final process is necessary but does not contribute to creating products for sale or profit, thus requiring an efficient and safe, cost-effective pumping solution. Self-priming centrifugal, flooded suction solids-handling, and submersible slurry pumps provide solutions to the wastewater process in paper mills.

Pumps for the Pulp and Paper Market

The pulp and paper production market is a competitive industry where manufacturers cannot afford downtime, lost production, equipment failures, or missed shipments. IPE is a leading pump supplier with valuable aftermarket service and pump repair to ensure pulp and paper mills achieve steady and reliable production rates. We provide complete pumping solutions including full system design, installation, testing, and service to ensure safe and efficient pumping processes for pulp and paper mills.

IPE offers a wide range of pumps and process equipment for the pulp and paper industry including:

• Slurry Pumps for Pulp and Paper Manufacturing – high-quality slurry pumps must perform necessary tasks for the paper and pulp industry, handling abrasive materials and corrosive chemicals. Slurry pumps can be positive displacement pumps, self-priming, submersible, or flooded suction.
• Self-Priming Pulp and Paper Pumps – self-priming pumps are a good choice in almost every process during pulp and paper manufacturing providing worry-free, reliable transfer of materials.
• Submersible Pulp and Paper Pumps – submersible pumps are an excellent choice in just about every pulp and paper manufacturing process with reliable performance in transferring wastewater or sludge and abrasive materials.
• Flooded Suction Pumps – flooded suction pumps are effective in transferring liquid and slurry from hoppers, storage systems, and tanks to other processes in pulp and paper manufacturing.

Illinois Process Equipment offers a variety of quality pumps and process equipment to meet the needs of the pulp and paper industry. We provide customer-focused equipment solutions to achieve maximum productivity and profitability.
