Wear resistant cast alloys are used for slurry pump liners and impellers where conditions are not suited to rubber, such as with coarse or sharp edged particles, or on duties having high impeller peripheral velocities or high operating temperatures.
Naipu Impeller is one of the most important parts of slurry pump. When impeller is rotating, the slurry pump could meet the requirements of the equipment. However, it is a component, which is worn out very easily. Therefore, for long service life of the impeller, the material plays an important role here.Naipu pump offers the two solutions for this problem. We choose the white iron, high chrome (27%) for the strong abrasive slurries, also with the sharp particles. For the corrosive slurries with blunt particles, we recommend the natural rubber.
