Material Description

The Parts have exchangeable  Material selection  Metal (A05, A49, A07),Elastomer(R08, R26 , R33, R55) and Polyurethane (U01)

Metal parts 

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.


Rubber Pump Parts

1.RU08 is a black natural rubber, of low to medium hardness. RU08 is used for impellers where superior erosive resistance is required in fine particle slurries.
2. RU26 is a black, soft natural rubber. RU26 is used for lines where superior erosion resistance to all other materials in fine particle slurry applications.
3. RU33 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.
4. RU55 is premium grade black natural rubber, it is suitable for severe erosive fine particle
