Pulp and Paper Pumps

Accurate and stable material handling is essential in stock preparation. SEEPEX N, T, and MD pumps handle fibers, adhesives, dyes, and coating colors. They work with both bleached and unbleached fibers.

These pumps maintain a steady flow and reduce pulsation. This ensures consistent and reliable results every time.

For long-distance fiber transport, Smart Air Injection (SAI) offers dense-phase conveying. Material moves in stable plugs at low pressure. This reduces blockages, limits wear, and uses energy efficiently.

The system also keeps pipelines clean naturally. Its compact design allows installation in tight layouts. Mills can move fibers safely and efficiently across long distances.

Precise chemical dosing is key in paper finishing. MD pumps deliver low-shear, low-pulsation dosing of dyes, additives, and finishing chemicals. SEEPEX Dosing Control (DOCL) integrates into automated mill systems. It works for both batch and continuous dosing.

SAI systems transport fiber-rich residues and viscous side streams. They maintain clean, odor-free operation and reduce wear. Digital monitoring is possible through fieldbus links and remote support. Scheduled maintenance is predictable, helping mills maintain uptime.

Coating requires careful handling of pigments, binders, and additives. SEEPEX pulp and paper pumps transfer these materials accurately to downstream processes. For coating residues and filler-rich rejects, SAI provides low-pressure, wear-reduced transport.

Controlled plug flow reduces buildup, simplifies disposal, and lowers lifecycle costs. Its compact design allows installation even in areas with limited space.

SEEPEX pulp and paper pumps handle bleaching chemicals, like caustic soda with precision. SEEPEX BN pumps deliver ±1% dosing accuracy while transferring black liquor during recovery. SAI moves abrasive by-products safely over long distances.

It reduces wear, improves safety, and helps mills meet availability targets. Custom system design and expert commissioning ensure optimal performance from the first day.

Effective wastewater management at paper mills ensures efficient operation and supports regulatory compliance. SEEPEX N-range pumps handle a wide range of process wastewater streams from pulp and paper production with reliable and consistent performance. T-range open hopper pumps convey highly viscous sludge generated during fiber recovery and treatment processes. MD pumps inject flocculants precisely where the treatment process requires them to maintain stable separation and dewatering.

SAI systems support long-distance transport of sludge and fiber-rich residues across the mill site. The system forms stable plugs at low pressure and keeps pipelines clean during operation. Digital control and predictable maintenance help reduce lifecycle costs. This ensures reliable conveying even in long or inclined pipelines between treatment units at pulp and paper facilities.
