Products detail
detail
The impeller is the core hydraulic component of a slurry pump, responsible for transferring mechanical energy from the motor into the slurry medium.
During operation, slurry containing solid particles flows through the impeller passages at high velocity, making it one of the most heavily worn parts in the pump system.
In mining and mineral processing applications, impeller wear directly affects pump efficiency, head performance, and overall system stability. High chrome alloy impellers are commonly used in abrasive conditions to improve wear resistance and maintain hydraulic performance.
As a critical spare part, the impeller plays a key role in determining the service life and efficiency of the entire slurry pump system.
Erosive and Corosive Applications-Alloys
| Code | Material # | Hardness HRC | Performance | Application |
| L05 | KmTBCr26 | ≥56 | Ranks second only to L07 in abrasion-resistant performance; fair corrosion-resistant performance. | High impact load abrasion condition; PH rate ranging from 5 to 12 |
| L07 | KmTBCr15Mo3 | ≥59 | Best abrasion-resistant performance; corrosion-resistant performance is inferior to L05 | High impact load abrasion condition |
| L11 | KmTBCrMnMo3 | 38-42 | Mild corrosion-resistant;lower hardness; dilling and tapping operations are applicable. | Fine particles with light abrasion. |
| L33 | 33%Cr Erosion&Corrosion Resistence White iron | ≥35 | Abrasion-resistant performance is close to L03; fair corrosion-resistant performance | Oxide slurry with PH rate no less than 1,like phosphor-gypsum in phosphate fertilizer plant,nitric acid, sulph-oacid and phosphoric acid,etc. |
| L49 | 28%Cr Low Carbon White iron | ≥43 | Fair abrasion-resistant performance, close to L03; fair corrosion-resistant performance in media with lower PH rate. | Corrosion conditions with low PH rate,especially for flue gas and FGD devices for media of PH≥4;general suitable for loweracid condition. |
| L12 | 30%Hyper eutectic hrominum White iron | 262 | Higher abrasion-resistant performance than L05; fair corrosion-resistant performance; suitable for media with PH rate is 6-16, where L05 is not suitable. | High abrasive slurry with fine particles. |
| L61 | 30%Cr High Chromium White iron | 63-68 | Optimized abrasion-resistant performance than L12 | High abrasive slurry with fine particles |
| L51 | 36%Cr,Low C | 48 | Higherabrasion-resistant performance than L05; fair corrosion-resistant performance; suitable for media with PH rate is 6-16, where L05 is not suitable. | High abrasive slurry with fine particles. |
