Iron Mining Pump Parts High Chrome Iron Cast Alloy Anti-Abrasive Long Life Slurry Pump High Chrome Impeller
OEM high chrome pump impellers
The function of the pump impeller is to transfer the energy input from the prime mover to the liquid. The structural forms of blades can be divided into cylindrical blades and twisted blades.Generally, the impeller of closed water pump has 2-12 back-curved blades with high operating efficiency. One single stage single suction centrifugal pump impeller because of the axial force, so some impeller in the root of the blade has a balance hole.The number of semi-open and open impeller blades is small, generally 2~5 pieces, most of which are used for pumping grainy liquid or sewage, such as the impeller of sewage pump. Water pump impeller material to have enough mechanical strength, and a certain wear resistance, corrosion resistance
Material

| R55 | Natural rubber | ≥46HA | Impeller / Liner | Have cut resistance, sharp slurries. Widely used in slurry pump parts. |
Production Process
- Aluminum Mold: Aluminum mold is able to ensure the accuracy in the cast process and make the blade curve infinitely close to the theoretical value. So that the efficiency of the pump can be improved.
- Heat treatment process: It can eliminate the stress, improve the hardness and prolong the work life.
- Boring and milling process: Professional boring and milling equipement to ensure accuracy.
- Product inspection: The products dimensions, hardness, compositon are strictly inspected by PV engineers
