Structure and Performance
Flow Rate Q: ~1800 m³/h
Head H: ~200m
Design temperature: 350°C
Design Pressure: 5.0 MPa
Structural Features:
1. The imported guide wheel increases the inlet pressure of the first-stage impeller, which is primarily designed for high cavitation resistance. This combination enables the pump to achieve a cavitation specific speed (C) as high as 2000–2500.
2. The first-stage pressure chamber employs radial guide vanes, reducing axial dimensions.
3. The secondary impeller employs a high-efficiency hydraulic design to enhance pump efficiency.
4. The secondary pressure chamber employs a spiral volute design to further enhance efficiency.
5. The modular single-face mechanical seal, supplemented by the Plan32 flushing scheme, enhances the pump’s sealing reliability and service life.
6. The large-diameter rigid shaft structure enhances pump reliability and operational smoothness.
Use of materials
1. Induction wheel, impeller: High-wear-resistant alloy Ni-Hard
2. Guide vanes, pump casing: Martensitic stainless steel 06Cr13Ni4Mo
3. Pump shaft: Precipitation-hardened stainless steel 17-4PH
