When traditional grab buckets fail and electric submersible pumps lack the torque to bite through hard-packed sediment, the TUSSU® Hydraulic Submersible Dredge Pump steps in. Engineered as a high-efficiency attachment for amphibious excavators, swamp excavators, and standard 20T to 50T class rigs, this hydraulic line delivers non-clogging suction power where you need it most.
By harnessing your excavator’s existing hydraulic system or a separate hydraulic power pack, TUSSU® bypasses the need for high-voltage electricity on-site. This makes it the go-to solution for deep-water dredging, harbor cleanouts, tailing ponds, and high-concentration slurry transportation.
Key Features & Engineered Performance
-
Excavator Mounted & Cable-Deployed Versatility: Easily swap out your standard bucket. The pump connects via a specialized hydraulic interface, turning your excavator into a high-production mobile dredger.
-
High-Chromium Alloy Wear Components: The volute, casing, and semi-open impeller are built entirely from heavy-duty, abrasion-resistant high-chrome alloy to withstand punishing sand, gravel, and rocks.
-
Active Agitator & Side Cutters: Equipped with a heavy-duty bottom agitator and optional dual side cutter heads to unearth, break up, and liquefy compact clay or thick silt before it enters the suction inlet.
-
Organic Waste Chopper: The internal mechanical design cuts through seaweed, marine growth, and aquatic weeds, eliminating downtime caused by clogs.
-
High Solid Concentration Handling: Capable of pumping slurries containing up to 70% solids by weight and handling large solid particles up to 120mm–150mm depending on the model size (available from 3″ up to 16″ discharge).
Deep Dive: What Operators & Project Managers Want to Know
1. How does a hydraulic dredge pump compare to an electric submersible pump?
The Short Answer: Torque and Safety.
Electric submersible pumps are great for fixed setups but often struggle with variable, hard-packed solids and require a massive electrical footprint or generator setup near water. TUSSU® hydraulic pumps deliver significantly higher torque, allowing the side cutters and agitator to grind through settled materials without stalling. Additionally, because it runs on hydraulic fluid rather than electricity, it is inherently safer for operators working in deep water or harsh marine environments.
2. Is it compatible with my existing excavator?
Yes. TUSSU® hydraulic slurry pumps are designed as versatile attachments for major excavator classes (typically ranging from small 120 models up to large 360 series). Compatibility is determined by matching your excavator’s hydraulic oil flow rate (L/min) and system pressure (Bar) to the pump’s hydraulic motor requirements. If your excavator’s flow is insufficient, the pump can easily be paired with an independent diesel hydraulic power pack.
3. Can this pump run dry or operate in shallow water?
While these pumps are specifically engineered for full submersion to optimize intake and natural cooling, they can operate in shallow water or fluctuating water levels. The critical rule is that the suction inlet and mechanical seals must remain covered by the slurry or liquid to maintain prime and prevent premature wear on the unique mechanical seal device.
4. What is the maximum pumping depth and distance?
The TUSSU® Growler and heavy slurry series can handle operating depths up to 250 meters, which is unattainable for conventional suction dredgers. Thanks to the high-head design (ranging from 5m to over 50m manometric head), it provides the necessary velocity for long-distance slurry transportation through discharge pipes directly to the shore or disposal site without needing secondary booster pumps.
Target Applications
