1.基本规格
规格和型号：
150: inlet diameter (150mm, DN150)
ZJ:slurry pump series (suitable for high-concentration solid-liquid mixed media)
A63: impeller diameter (630mm) or design code
type: centrifugal slurry pump (special for filter press)
Flow range: 200-450m³/h (adjustable)
Head: 40-80m (adapt to the high-pressure feeding requirements of the filter press)
2.结构设计
Material of flow-through parts: Pump casing/impeller: high chromium alloy (Cr28, hardness ≥60HRC) or rubber lining (corrosion resistant)
Shaft seal: double-end mechanical seal + auxiliary impeller dynamic seal (leakage prevention)
Bearing box: heavy-duty oil lubrication design (adapt to high-load operation)
3.Power and performance
Motor power: 90-200kW (frequency control optional)
Speed: 980-1480r/min (low speed reduces wear)
Allowable particle size: ≤10mm (matching filtering device is required)
Working pressure: ≤1.6MPa (adapt to the high pressure stage of filter press)
4.Filter press adaptability
Performance curve: steep characteristics (large flow and low pressure automatic transition of small flow and high pressure)
Sealing reliability: leakage at shaft seal ≤5ml/h (in line with API682 standard)
5.Equipment size and weight
Overall dimensions: ≈1800×1200×1500mm (length×width×height) Machine weight: 2.5-3.5 tons (depending on the material)
Selection suggestions
1. High wear conditions (such as iron ore tailings): high chromium alloy impellers are preferred.
2. Corrosive media (such as acidic slurry): rubber lining + 316L stainless steel shaft is used.
3.维护点：
Check the impeller clearance every month (standard value 0.5-1mm)
Replace the bearing grease every quarter (high temperature resistant type)
If performance curve (QH) or wear test report is required, please specify the specific media characteristics (such as solid content, pH value, etc.).
