Paper & Pulp Industry Solutions

Rotho peristaltic pumps handle the demanding fluids of paper manufacturing - from fibrous pulp stock to shear-sensitive coatings to precise chemical dosing.

Paper & Pulp Challenges

Paper mills process extremely fibrous materials alongside shear-sensitive coatings and aggressive chemicals. Pumps must handle pulp with long fibers, deliver coating colors without damage, and accurately meter process chemicals.

Fibrous Materials: Long cellulose fibers wrap around impellers and clog conventional pumps
Shear-Sensitive Coatings: Clay coatings and latex binders are damaged by aggressive pumping
High Solids: Pulp stock contains 3-15% suspended fiber
Chemical Dosing: Bleach, alum, and sizing chemicals require precise metering
Abrasive Fillers: Calcium carbonate and titanium dioxide wear pump components

Why Rotho for Paper & Pulp

Purpose-built features for paper manufacturing

Handles Fibrous Pulp

No impeller to wrap with fibers, no seals to clog. The progressive compression action moves long cellulose fibers cleanly through the pump without binding or entanglement.

No fiber wrapping
No clogging
Passes stringy materials
Self-cleaning action

Preserves Coating Quality

Gentle rolling action transfers clay coatings, latex binders, and pigment slurries without breaking emulsions or altering viscosity. Preserves coating performance and appearance.

Low shear transfer
No emulsion breakdown
Maintains viscosity
Preserves gloss

Precise Chemical Dosing

Accurately meter bleach, alum, rosin size, retention aids, and other process chemicals. Linear flow-speed relationship ensures consistent dosing for uniform paper quality.

Accurate metering
No slip
Signal controlled
Chemical resistant

Handles Abrasive Fillers

Reinforced hoses handle calcium carbonate, titanium dioxide, and other mineral fillers that destroy conventional pump seals. Single wear item keeps maintenance simple.
