Structural Specifications
- Features an open-type, shroudless design with independently cast, thick, deep vanes; offers a spacious flow passage with no dead zones, minimizing the risk of slag accumulation or clogging.
- The hub includes a standard keyway and shaft sleeve interface, compatible with vertical pump shaft assemblies; optional back vanes can be added to reduce wear and leakage.
- Precision-machined and dynamically balanced; can be integrated with optional front agitation vanes to enhance agitation of settled media at the tank bottom and prevent sediment buildup.
- Designed specifically for the vertical slurry pump; allows for adjustable clearance with the pump casing and wear plate; suitable for vertical cantilever or submerged installation configurations.
Key Features
1. **Excellent Solids Handling:** The open, unobstructed structure allows for the smooth passage of large solid particles and long-fiber impurities; resistant to clogging or entanglement, making it ideal for high-solids applications.
2. **High Wear Resistance & Durability:** Heavy-duty vane design with optional surface hardening on flow-contact areas; withstands high-velocity particle erosion and offers a long service life.
3. **Stable Operation:** High dynamic balancing precision ensures stability in vertical long-shaft cantilever applications; minimizes vibration and noise, thereby reducing loads on the shaft assembly and bearings.
4. **High Adaptability:** Available in various materials, including wear-resistant metal, polyurethane, and rubber; standardized specifications ensure easy installation/removal and excellent spare part interchangeability.
5. **Application Versatility:** Double-suction flow path design reduces axial thrust; suitable for continuous submerged operation with no risk of dry-running cavitation, resulting in low maintenance costs.
