FMB series of corrosion-resistant and wear-resistant temperature-resistant centrifugal pumps, the current-flow parts are made of steel lining, which is now made of a new generation of corrosion-resistant and wear-resistant alloys. The pump combines outstanding wear resistance, impact resistance, corrosion resistance and high temperature resistance. It is designed with K-shaped dynamic seal (FMB-ZK) and built-in single-end mechanical seal (FMB-ND). Built-in double-face mechanical seal (FMB-NS) three sealing structures, can adapt to various working conditions. It is especially suitable for transporting acid, alkaline liquid or slurry; various corrosive pulps in the smelting industry; various organic acids, strong oxidants, various types of sewage in the environmental protection industry, etc., and the application range is very wide.
