- High Efficiency & Wear Resistance: Made of high-chromium alloy materials (e.g., Cr27, Cr30A) or rubber-lined for superior wear and corrosion resistance, suitable for highly abrasive slurries.
- Large Flow Capacity: Optimized hydraulic design provides a wide flow range (up to thousands of cubic meters per hour) with moderate head, meeting high-concentration transport demands.
- Multiple Sealing Options: Includes auxiliary impeller + packing seal, mechanical seal, or combined sealing to adapt to different working conditions (e.g., high pressure, corrosive environments).
- Modular Design: Quick replacement of wet-end components (impeller, casing, front/rear liners, etc.) for easy maintenance.
- Various Drive Methods: Supports direct motor coupling, belt drive, or gearbox drive to accommodate different power requirements.
- Pump Head: Includes the volute (metal or rubber-lined), impeller (closed/open type), and liners, which directly contact the slurry and require periodic replacement.
- Shaft Sealing System: Different sealing configurations (e.g., dynamic sealing with auxiliary impeller) reduce shaft pressure and extend service life.
- Bearing Assembly: Heavy-duty bearing housing with oil lubrication ensures stable operation under high loads.
- Transmission Unit: Connects to the motor via flexible coupling or pulley, with some models supporting variable frequency speed control.
- Head (H): 10–150 m
- Inlet/Outlet Diameter: 25–450 mm
- Max. Particle Size: Generally ≤50 mm (larger sizes possible with special design).
- Solids Concentration (by weight): Up to 60% or higher (depending on medium properties).
- Mineral Processing: Transporting tailings, concentrates, or cyclone feed.
- Coal Washing: Handling coal slurry or dense medium suspensions.
- Power Plant Desulfurization: Circulating limestone slurry or gypsum slurry.
- Dredging Operations: Pumping high-sediment sludge.
- Chemical Processes: Corrosive slurry transport (requires corrosion-resistant materials).
- Operating Conditions: Flow rate, head, and inlet pressure must match the pump’s performance curve.
- Installation Environment: Choose between horizontal/vertical mounting or submersible designs if needed.
- Replace Wear Parts: Impellers, liners, and other wear components should be replaced periodically.
- Avoid Dry Running: Flush the pump chamber before shutdown to prevent solid buildup.
