Abstract：With the rapid development of paper industry and the paper industry technical equipment introduction and technical transformation investment attention, had an obvious change paper industry equipment enterprises scale, technology level, production capacity. Pulp pump as a main pulp conveying machinery, due to the advantages of high efficiency, energy saving, good cavitation performance, long life, high concentration, reasonable structure, plays an important role in pulp and paper mill, sugar industry, city sewage disposal industry and other industries, and has been widely used. Pulp pump is to rely on the role of the rotating impeller on the liquid is the prime mover of the mechanical energy transmitted to the liquid. Due to the effect of pulp pump, liquid from the impeller inlet process flow of exports, its speed and pressure are increased, the impeller discharge liquid through the discharge chamber, most speed can be converted into kinetic energy, in the impeller under the action of centrifugal force, so the discharge line to transfer out,, the continuous rotation of the impeller continuous suction and discharge of liquid.
