1. Basic specifications
model analysis:
HZ: chemical/heavy-duty centrifugal pump (H chemical, Z heavy-duty)
200/150: inlet and outlet diameters (200mm inlet/150mm outlet)
SA: special alloy (Super Alloy) lining or material code
Type: centrifugal slurry pump (designed for high-concentration slurry in thickeners)
Flow range: 300-600m³/h (slurry concentration 30%-50%)
Head: 20-40m (multi-stage series connection is possible)
2...Structural design
Material of flow-through parts:
Pump casing/impeller: high chromium alloy (Cr28, hardness ≥62HRC) or rubber lining (wear and corrosion resistant)
Shaft seal: double-end mechanical seal + flushing water system (adaptable to solid media)
Corrosion resistance: pH 2-12 (optional 316L stainless steel or fluorine- lined design)
3.Power and performance
Motor power: 75-160kW (frequency control, adapt to flow fluctuations)
Speed: 980-1480r/min (low speed reduces wear)
Allowable particle size: ≤10mm (grid filter required)
Working pressure:≤1.0MPa
4.Concentration process adaptability
Solid-liquid ratio adjustment: support 1:4~1:6 slurry transportation (refer to the solid-liquid ratio requirements of the concentrator) Anti-clogging design:
Large channel impeller (throughput capacity increased by 30%) Backwash interface (optional)
5.Safety and intelligent control
Monitoring system:
Bearing temperature vibration sensor (early warning fault)
Flow pressure interlock (linked with the concentrator)
Explosion-proof option: Ex dⅡ BT4 (flammable and explosive environment)
6.Equipment size and weight
7.Overall dimensions: ≈1800×1200×1500mm (length×width×height)
Machine weight: 1.5-2.5 tons (depending on the material)
Selection suggestions
1.High wear conditions (such as iron ore tailings): high chromium alloy impeller + ceramic liner is preferred.
2.Corrosive media (such as acidic slurry): full fluorine lining or 316L stainless steel pump body is used.
3. Maintenance points:
Check lining wear every month (thickness <5mm needs to be replaced) Lubricate the sealing system every quarter (corrosion-resistant grease) If performance curves (QH) or material corrosion resistance test data are required, please specify the specific medium composition (such as Cl concentration, solid hardness, etc.).
