What are the impeller materials?

Impeller is an important part of sand pumping pump, common impeller materials include the following:

1. cast iron:

Lower cost, with a certain degree of wear resistance and corrosion resistance.

2. stainless steel:

Good corrosion resistance, suitable for some special working conditions.

3. cast steel:

High strength, good wear resistance. 4.

4. high chrome alloy:

Excellent abrasion resistance, commonly used in conveying high abrasion medium. 5.

5. ceramic:

Have very high wear resistance and corrosion resistance.

6. plastic:

Light weight, good corrosion resistance, suitable for some special media.

7. composite materials:

Combined the advantages of a variety of materials, with better performance.
When choosing the impeller material, the following factors need to be considered:

1. medium characteristics:such as corrosive, abrasive, etc.

2. operating conditions:including temperature, pressure, etc.
3. cost:the price of different materials varies considerably.
4. Wear resistance:ensure that the impeller has sufficient wear resistance.
5. Strength Requirements:meet the mechanical requirements in the work.
6. Corrosion protection:according to the corrosiveness of the medium to choose the appropriate material.
