Pulp and paper manufacturing processes run 24/7 with fibrous cellulose pulp slurries, corrosive black liquor, and aggressive chlorine bleaching chemicals. Fibers naturally aggregate around mechanical seal faces, leading to de-watering, face separation, and spring fouling. USEC designs clog-resistant mechanical seals specifically engineered for paper stock and liquor pumps.
The paper industry encompasses processes that necessitate highly precise and resistant seals when working with aggressive chemicals as well as high-speed equipment. Our products are set up for pulp preparation, paper machines, and finishing equipment while ensuring there is consistency in performance.
We provide reliable sealing solutions that boost productivity while sustaining a viable operation in the paper manufacturing sector.
Wood fibers squeeze into seal face gaps, de-watering the dynamic interface and burning seal rings.
High-alkalinity black and green liquor with silica content causes caustic stress corrosion on pump hardware.
Pumping paper stock with up to 6% consistency requires non-clogging open spring arrangements.
