Pulp and Paper
Pumps for kraft pulp, white/black liquor, process waters and pulp industry effluents
ASME B73.1API 610
The pulp and paper industry is one of the most demanding in pumping: cooking liquors with high alkalinity, pulp with abrasive fibers, bleaching chemicals and process waters with variable solids. FB Bombas serves these plants with FBCN centrifugal pumps in CF8M (316) for process waters, white and black liquor, chloride-resistant, and special configurations for kraft pulp with open or semi-open impellers. We also supply FBOT pumps for digester heating systems and heat recovery.
Typical Fluids
Fluids we serve in this segment
Unbleached kraft pulp

Black liquor in evaporation
Bleaching chemicals (ClO₂, O₃, H₂O₂)
Process water with fibers
Evaporation condensates
Pumping Challenges
Problems we solve in this sector
Very high alkalinity combined with high temperature
Abrasive fibers in suspension

We serve applications with: Unbleached kraft pulp, White liquor (NaOH + Na₂S), Black liquor in evaporation, Bleaching chemicals (ClO₂, O₃, H₂O₂), among others. Each fluid is chemically analyzed before material and configuration selection.
Frequently used materials: CF8M / AISI 316. Final choice is made after chemical analysis of customer fluid by our engineering.
Typical challenges: Very high alkalinity combined with high temperature; Abrasive fibers in suspension; Chloride chemical attack. Our engineering sizes the solution considering all these factors together.
We work with ASME B73.1, API 610. For specific projects, other sector standards may apply (e.g. ATEX for classified areas in chemicals).
Yes. FB Bombas has served Brazilian industry for 82+ years (since 1944) with documented history in multiple segments. We are Petrobras CRCC-registered — relevant qualification for Pulp and Paper in Oil & Gas projects.
Yes. Our retrofit service is particularly effective in Pulp and Paper — enables technological upgrade keeping original casing, base and piping, reducing CAPEX and downtime.
