1. The Heavy-Duty Challenge in Modern Dredging
In mining, river maintenance, and marine construction, traditional surface-mounted pumps or mechanical excavator buckets constantly hit a bottleneck. Standard pumps fail prematurely due to severe abrasion, lose prime in deep water, or clog when encountering high-density slurries.
When your project demands the relocation of thick mud, heavy sand, or mineral tailings, you don’t just need a pump—you need an industrial-grade powerhouse that thrives in the harshest underwater environments.
Enter the TUSSU® Hydraulic Submersible Abrasive Dredge Handling Pump.
2. Why Choose TUSSU® Hydraulic Drive Submersible Pumps?
Unlike electric-driven alternatives that risk motor burnout under heavy loads or require complex electrical infrastructure in remote sites, TUSSU® hydraulic slurry pumps deliver maximum torque across the entire speed range.
Engineered to seamlessly integrate with your existing fleet—including CAT, Komatsu, Volvo, and Sany (20t to 100t excavators)—or independent hydraulic power packs, our pumps turn your machinery into a high-performance dredging matrix.
Key Performance Specifications:
| Feature | Technical Capability |
| Discharge Size | 80mm to 400mm |
| Flow Rate (Capacity) | 50m³/h to 1,500m³/h |
| Max Head | Up to 60 meters |
| Solid Concentration | Up to 70% by weight |
| Max Particle Size | Up to 50mm – 60mm |
3. Cutting-Edge Engineering Features That Outlast the Competition
Active Agitation: Zero Clogging, Maximum Density
Standard suction pumps often only pump water while the heavy solids remain settled at the bottom. TUSSU® pumps feature an integrated bottom mixing mechanism and can be outfitted with bilateral or multilateral side hydraulic agitators. These cutters active fluidize settled solids, creating a high-density slurry mixture for continuous, high-concentration extraction.
High-Chrome (A05) Wear-Resistant Metallurgy
Abrasive sand and gravel can destroy inferior impellers within weeks. All wetted parts of TUSSU® dredge pumps—including the pump casing, impeller, wear plates, and mixing agitator—are cast from premium high-chrome alloy (A05 / Cr27). For specialized chemical or hyper-abrasive environments, we offer custom metallurgy including duplex stainless steel (2205) and SS316L.
Advance Sealing Technology
Underwater operations demand absolute reliability. TUSSU® employs a unique mechanical seal system isolated within a specialized oil chamber. This design eliminates frequent seal changes, prevents fluid ingress, and guarantees hundreds of hours of maintenance-free operation.
4. Built for Global Heavy Industries: Primary Applications
TUSSU® Hydraulic Submersible Abrasive Dredge Handling Pumps are globally trusted across versatile sectors:
-
Mining & Tailings Management: Efficient transport of abrasive mineral processing waste, gold/copper tailings, and clearing out remote sedimentation ponds.
-
Harbor, Marina & River Dredging: Removing heavy silt, gravel, and sand from commercial navigation channels and restoring depth without large, expensive dredging vessels.
-
Land Reclamation & Beach Nourishment: Pumping massive volumes of sea sand for coastal engineering and infrastructure expansion.
-
Remote & Off-Grid Infrastructure: Powered by excavator hydraulics or diesel power packs, these pumps require zero onshore electrical setup, making them ideal for wild terrain projects.
5. The TUSSU® Advantage: Lower Total Cost of Ownership (TCO)
By bypassing the limits of traditional suction-lift physics, TUSSU® submersible pumps operate directly within the material. This eliminates priming issues, reduces energy cavitation, and delivers unmatched solid-to-liquid ratios (up to 70% solids).
Fewer mechanical components, rugged wear materials, and versatile attachment options mean your project experiences minimal downtime and significantly lower operational costs per cubic meter.
