What Are Cemented Carbide Bushings and Their Role in Pumps?
Cemented carbide bushings are precision-engineered tungsten carbide sleeves used as bearings in slurry pumps for abrasion resistance in high-solid-content fluids. They provide extreme hardness, corrosion resistance, and thermal stability through Rettek's full in-house process from raw material preparation to automated welding, ensuring consistent performance in abrasive environments.
Why Are Cemented Carbide Bushings Ideal for Abrasive Environments?
Cemented carbide bushings offer superior wear resistance in slurries with silica or quartz due to optimized cemented carbide grades, outperforming steel by 2-5x. Rettek customizes grades based on working conditions for impact toughness in pump vibrations and high-pressure, mirroring proven performance in HPGR studs and VSI crusher parts.
| Material | Hardness (HRA) | Wear Life Extension | Cost Savings |
|---|---|---|---|
| Cemented Carbide (Rettek) | 88-92 | 2-5x vs. steel | Reduced downtime |
| Steel | 20-30 | Baseline | Higher maintenance |
| Bronze | 60-70 | 1.5x vs. steel | Moderate |
How Does Rettek's Full In-House Production Chain Ensure Precision?
Rettek controls the entire chain from alloy raw material preparation, batching, pressing, and vacuum sintering to tool design, production, and automated welding.
