  • Features of 2T 8T Inner & Outer Ring Bushing Set for Vertical Multistage Pumps

    (1) Hardness and Wear Resistance

    The MH series new materials exhibit the characteristic that the lower the density, the higher the hardness. This leads to a decrease in the impact resistance coefficient as the hardness increases. The wear resistance coefficient is directly proportional to the hardness.

     

    (2) Corrosion Resistance

    Due to the formulation, the new materials have stable chemical properties. They can be used in acidic and alkaline environments, but environments with strong acids (such as concentrated sulfuric acid with a content of over 70%) and high temperatures should be avoided. Acid and alkali resistance tests show that the chemical properties in acidic environments are superior to WC.

     

    (3) Wear Test

    In experiments with added mud, abrasives, and iron filings, the wear loss of the new material MH2 was 0.02 mm, WC was 0.02-0.04 mm, and SiC was over 1 mm.
