In the pulp and paper industry, handling high-volume, dense slurries with high solid content is a significant challenge, requiring robust and reliable equipment to ensure uninterrupted production. The use of medium to high consistency (10-48%) pumping has been employed since the late 1950s to reduce water use, energy consumption, and storage space. This approach also leads to more compact equipment and facilities. However, achieving this efficiency and reliability is only possible with the right industrial-grade pumps.
The Importance of Reliable Fluid Handling in Pulp Production
Medium consistency pumps can operate at consistencies up to 16%, reducing effluent volume, energy costs, and chemical usage. These pumps use high shear forces to achieve a fluid-like state in the pulp, and they include zones for breaking down the fibre network and separating gases. The industry relies heavily on industrial-grade pumps, hoses, and filters to handle the harsh conditions. For example, pumps from manufacturers like Roper are engineered to handle the tough demands of pulp and paper applications.
Roper Pumps: The Solution for Pulp and Paper Fluid Handling
Roper Pumps have become a cornerstone in the pulp and paper industry due to their robust construction and ability to handle high-viscosity fluids. Whether it's pumping starches between processing stages, transferring starch-based ingredients, or handling starch-derived materials in industrial processes such as paper manufacturing, pulp processing, and corrugated cardboard plants, Roper pumps offer an ideal fluid handling solution.

Gear Pumps for Pulp Processing
Roper also boasts a complete line of helical gear pumps designed for the industrial, transport, and oil and gas marketplaces. These pumps are engineered to handle the demanding conditions of pulp processing, ensuring reliable operation and long service life.
High Solid Content Slurry Pumps
In pulp mills, the most energy-intensive step in thermomechanical pulping is refining, with refiners consuming up to 88% of the total electricity in a TMP mill. Heat recovery is often used to recover some of this refining energy in the form of clean, pressurized steam. High solid content slurry pumps like those from Roper are crucial in this process, as they can handle the abrasive and corrosive nature of pulp slurries efficiently.
Robust Industrial Pumps for Pulp
Pulp pumps are an indispensable component in many industrial processes, particularly for transporting and processing pulp slurries. These pumps are designed to withstand the abrasion and corrosion caused by fibrous slurries over long operating lifetimes. They consist of a rotating impeller enclosed in a volute casing that accelerates and displaces the pulp mixture for transport.
Reliable Fluid Transfer in Paper Production
The use of medium-consistency pumps has proven to be highly effective in reducing effluent volume, energy costs, and chemical usage. These pumps use high shear forces to achieve a fluid-like state in the pulp, and they include zones for breaking down the fibre network and separating gases. By selecting the right pump for your specific process requirements, you can optimize pulp pumping productivity and efficiency.
