12 14 Inch Sand Suction Pump Mud Gravel Dredge Slurry Gold Dredge Pump Heavy Duty Long Distance River Dredging Electric Diesel Centrifugal Gold Mining Suction

The gravel pump series is designed for continuous transportation of highly corrosive materials that cannot be handled by ordinary sand pumps due to large particle sizes. It is ideally suited for dredging by dredgers, river cleaning, mining, and metal smelting slag transport.

Featuring a single pump shell structure with a spacious flow channel, the over-flow parts are crafted from hard nickel, high chromium, and other wear-resistant alloys. The discharge direction can be adjusted to any 360° position, offering excellent cavitation performance and corrosion resistance.

• Dredging of rivers and ports: Pumping highly abrasive mud and sand containing pebbles and shells (up to 300 mm).
• Sand mining ships: Continuous transport of gravel-sand mixtures at concentrations up to 50% by volume.
• Mining tailings backfilling: Pumping coarse tailings to underground goafs with heads up to 80 meters.
• Aggregate washing: Lifting sand-containing wastewater at rates up to 9360 m³/h.
• Sea sand desalination: High-chromium casting resists chloride ion corrosion in high-salt environments.
