Combined Material, Pump Design and Manufacturing Method Gives Good Results in Fertilizer Industry

Cost saving is not the best way to achieve good results, but investing in the right products and materials is. Different metallic pump materials and manufacturing methods have been developed for various fertilizer processes. They build on the raw materials used in the production, process conditions in different pumping stages, process know-how, and the material itself. To specify the material of construction based on corrosion resistance alone is not enough, but mechanical properties also need to be considered when selecting pump materials for different pumping stages in the production process for fertilizers. The effect of different components on the abrasion and corrosion resistance in the microstructure of various types of cast irons used in the industry is decisive as well. Pump design features such as flow velocity, wall thickness and seal cavity combined with application knowhow and material selection gives the best result. The development of new coatings and 3D printing technology opens new opportunities for both equipment suppliers and end users.
