Paper & Pulp Industry

Paper and pulp mills handle some of the most challenging fluids in industry — fibrous stock at varying consistencies, abrasive white water laden with fillers and fines, corrosive black and green liquor in chemical recovery loops, and aggressive bleaching agents. Pumps in these duties must combine wear resistance with the ability to pass long fibres without clogging. Weltech's paper & pulp pump range is built specifically for this profile — open-impeller hydraulics for fibre passage, hard-facing options for abrasion resistance, and corrosion-resistant material specs for recovery and bleaching duties. Our pumps support the full mill from stock preparation through chemical recovery to effluent treatment, reducing downtime in operations where every hour of standstill costs production tonnes. TYPICAL APPLICATIONS • Stock & broke circulation — pulp slurry transfer between chests at varying consistencies • White water & saveall — circulation of filtered water with fines and fillers • Chemical recovery — black liquor, green liquor, and weak wash transfer in kraft mills • Effluent treatment — mill discharge handling through clarifiers and aeration tanks
