Features and Applications
High Wear Resistance
Flow Parts (such as volute liner, impeller, and expeller) are typically manufactured from wear- and corrosion-resistant materials, such as high-chromium alloy cast iron, rubber linings, and polyurethane (PU), to withstand the abrasive wear caused by solid particles.
High Passability
The structural design ensures that larger particles can pass through smoothly, preventing blockages. Open or semi-open impellers are typically used, featuring fewer blades and wide flow channels.
Heavy-Duty Construction
Load-bearing components such as the shaft, bearing housings, and frame are robustly constructed to withstand heavy and impact loads, ensuring stable operation and a long service life.
Various Sealing Methods
Expeller dynamic seal
Relying on the back pressure generated by the auxiliary impeller during pump operation to prevent slurry leakage. This design is simple and requires no external seal water, but places high demands on the seal during shutdown.
Mechanical seal
Suitable for applications where leakage is not permitted or where hazardous media are transported, but requires a flushing water system.
Gland Packing seal
Simple structure and low cost, but requires seal water and involves some leakage.
Wide-ranging Applications
- Mineral processing plants: Transporting raw ore slurry, concentrate, and tailings.
- Coal industry: Transporting coal slurry and heavy-medium suspensions.
- Power generation industry: Transporting ash and desulfurization slurry.
- Dredging and river channel dredging.
- Transport of solid-liquid two-phase flows in the metallurgy, chemical, and building materials industries.
Main Types
By structural configuration
Horizontal slurry pumps, vertical (submersible) slurry pumps.
By number of pump casings
Single-casing pumps (Integral Pump Casing), double-casing pumps (with wear-resistant lining; the outer casing bears the pressure and is easy to replace).
By application
Heavy-duty slurry pumps, light-duty slurry pumps, dredging pumps, desulfurization pumps, etc.
Key parameters for selecting mining slurry pumps
- Flow rate (Q): The volume of slurry to be conveyed per unit time (m³/h).
- Head (H): The total pressure head the pump must provide (m).
- Slurry Characteristics: Specific gravity of solid particles, concentration (by weight or volume), particle size distribution, particle hardness and shape, and slurry pH. These factors are critical in determining the pump's material, type, and service life.
Key Points for Operation and Maintenance
- Proper Installation: Ensure good suction conditions to prevent cavitation; achieve precise alignment to minimize vibration.
- Optimal Operation: Operate within the high-efficiency range to avoid rapid wear caused by low or high flow rates.
- Regular Maintenance: Check bearing temperature, vibration, and seal condition; change lubricating oil regularly; monitor the thickness of flow-through components and replace worn parts promptly.
- Strategic Spare Parts: Stock up on wear-prone components (volute liner, impeller, expeller and shaft sleeves) based on wear cycles.
Mining slurry pumps are heavy-duty equipment designed for harsh operating conditions, and their selection, operation, and maintenance require a high degree of expertise.
Correct selection (based on accurate slurry parameters) and standardized maintenance are fundamental to ensuring long-term, high-efficiency, and low-cost operation.
In practical applications, it is typically necessary to collaborate with professional manufacturers or engineers to perform detailed calculations and design solutions.
