Paper and pulp production starts with the cutting down of trees into logs followed by debarking and chipping to prepare the raw materials for the paper processing cycle. The wood chips are then fed into a large digester tank where, with the help of acid, the lignin is dissolved to help separate the plant fibers. Additives and dyes are then added to the wood-free pulp solution. The whole process requires the pumping of corrosive and abrasive slurries as they move from one location to another, an activity that can cause significant damage to conventional centrifugal pumps.
