Key Performance Features
Superior Abrasion Resistance: Wet-end components (impeller, casing, back liner) are cast from high-chrome alloy (hardness ≥60HRC) to withstand the impact of large rocks and gravel.
Non-Clogging Design: The unique wide-passage impeller ensures the smooth passage of large solids, significantly reducing downtime in dredging and tunneling projects.
360° Discharge Rotation: The heavy-duty single-casing structure is connected by clamping bands, allowing the discharge direction to be oriented to any of 8 positions to fit any plant layout.
Easy Maintenance: The simple bolt-on design allows for quick disassembly and replacement of wear parts, minimizing operational costs.
Primary Applications
River & Sea Dredging: Perfect for sand reclamation and channel deepening involving large stones.
Mining Operations: Ideal for ball mill discharge and coarse tailings transport.
Tunneling & Construction: Handling slurry containing crushed debris in shield tunneling projects.
Industrial Waste: Transporting granulated slag or abrasive slurries in metal smelting.
