1) material: R08, R26, R33, R38, R55, S02, S12, S21, S42, S44,S50, U01, EPDM, PU etc. R08is a black natural rubber, of low to medium hardness. RU08 is used for impellers where superior erosive resistance is required in fine particle slurries. R26 is a black, soft natural rubber. RU26 is used for lines where superior erosion resistance to all other materials in fine particle slurry applications. R33 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. R55is premium grade black natural rubber, it is suitable for severe erosive fine particle slurries.
S21 we called Butyl rubber is a high saturated elastomer which has excellent chemical stability and good resistance to heat and oxidation.The high saturation reduces the elastomeric properties of S21,and hence reduces its erosion resistance.In general S21 is used in acidic environments. S31 is an oxidation and heat resistant elastomer.It has a good balance of chemical resistance to both acids and hydrocarbons. S42 Neoprene is a high strength synthetic elastomer with dynamic properties only slightly inferior to natural rubber.It is less effected by temperature than natural rubber,and has excellent weathering and ozone resistance.It also exhibits excellent oil resistance.
Product Overview
Other Related Metal Pump Parts
Our Metal Parts material mainly is A05,A07,A49.
1.A05 is a wear resistant white iron that offers excellent performance under erosive conditions. The alloy can be effectively used in a wide range of slurry types. The high wear resistance of alloy A05 is provided by the presence of hard carbides within its micro-structure. Alloy A05 is particularly suited to applications where mild corrosion resistance, as well as erosion resistance is required.
2.A07 Marten-sic white iron with moderate erosion resistance.
3.A49 is suitable for low pH corrosion duties, where erosive wear is also a problem. The alloy is particularly suitable for Flue Gas Desulphu-rization(FGD) and other corrosive applications, where the pH is less than 4. The alloy can also be used in other mildly acidic environments. A49 has an erosion resistance similar to that of Ni-Hard 1.
