The rubber parts are wear resistant and corrosiem resistant, usually used for acid working conditions, such as tailing in mining industry, slurry with small particles and no rough edges. The whole displacement part includes Cover Plate Liner, Throat bush, Frame plate liner, Frame Plate Liner Insert. The rubber spare parts material is natural rubber, synthetic rubber, EPDM Rubber, Nitrile Rubber, Fluororubber or any other as requests, which guarantees excellent performance including wear resistance, chemical resistance , waterproof and higher operating temperature range from -40-75℃.
The rubber Pump Liners: Easily replaceable liners are bolted, not glued, to the casing for positive attachment and ease of maintenance. Hard metal liners are completely interchangeable with pressure molded elastomers. Elastomer seal rings back all liner joints.
Main Rubber Material Emtroduction:
• NR08 is a black natural rubber, de low para medium hardness. NR08 is used for impellers where superior erosive resistance is required in fine particle slurries.
• NR26is a black,soft natural rubber. NR26 is used for lines wheresuperior erosion resistance to all other materials in fine particle slurry applications.
• NR33 is a premium grade black natural rubber of low hardness and is used for cyclone and pump liners and impellers where its superior physical properties give increased cut resistance to hard, sharp slurries.
• NR55 is premium grade black natural rubber, it is suitable for severe erosive fine particle slurries.
