Shijiazhuang Naipu Pump Co.,Ltd is a professional slurry pumps factory. Our Slurry pump is made up of Frame Plate, Cover Plate,Throat Bush,Cover Plate Liner, Frame Plate Liner, Impeller,Back liner,Expeller Ring,Base, Bearing Housing etc.


Horizontal Slurry Pump Spares-Impeller

The impeller is the main rotating component which normally has vanes to impart the centrifugal force to the liquid.Usually,slurry pump impellers have a plain or a Francis type vane.
The plain vane has a leading edge square to the back shroud,whereas the Francis vane has a leading edge projecting into the impeller eye.
Some advantage of the Francis vane profile are the higher efficiency,improved suction performance and slightly better wear life in certain types of slurry because the incidence angle to the fluid is more effective.





Slurry Pump spares material
 
Slurry pump Impeller part code: B1052, B15127, C2127, D3147, E4147, F6147, FAM8147, G8147, G10147, G12147, GAM14147...
 
1) impeller material: A05,A07,A49,A61,N23 etc.
2) There are 3-6 impeller vanes. It depending on the size of the particles in the slurry.
3) Impeller type including Close, Semi-open and Open type. Impellers are generally closed because of higher efficiency and are less prone to wear in the front liner region. Open impellers are more common in smaller pumps or where particle blockage may be a problem or where the shear provided by an open impeller is an aid to pumping froth.

4) We can also produce the non-standard impellers for some special situations.
    a)Pumping coarse coal
    b)Pumping fibrous material
    c)Reduced diameter impellers
    d)Reduced eye impellers

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.
