Hydraulic Dredge Pump with 2 Side Cutters
HAWK’s hydraulic dredge pump with two side cutters is used to load sand, gravel, and other abrasives into the hopper of a dredge. A hydraulic motor that supplies power to the hopper and cutting discs drives it. This hydraulic submersible dredge pump can also be used with an auger feeder to transport material from one place to another.
The unit consists of a small box containing pulleys, rope sheaves, bearings, and seals that allow it to turn freely within its housing without rubbing against any part of the housing wall or other moving components such as belts.
HAWK’s dredge slurry pump hydraulic machine with 2 side cutters has the following features:
- Firmly welded steel plate body and high-quality components
- Each pump set has one main hydraulic cylinder and two side hydraulic cylinders.
- Individual control of each hydraulic cylinder allows precise adjustment of each cutting blade to suit the working conditions.
- High-efficiency, low-consumption jet pumps are driven by a direct current motor and a gearbox that allows maximum efficiency at all times.
In order to achieve a more perfect fit, HAWK can customize the size according to the needs of customers.

Frequently Asked Questions
What is a hydraulic dredge pump with 2 side cutters?
A hydraulic dredge pump with two side cutters is a type of submersible dredge pump designed for efficient material removal in dredging operations. It features powerful hydraulic pumps for excavators and two mechanical side cutters that facilitate the loosening and cutting rigid materials on the seabed or riverbed.
How does the hydraulic dredge pump function?
The hydraulic dredge operates by using a combination of suction and mechanical cutting. The submersible dredge pump creates a vacuum that lifts sediment and debris from underwater. Concurrently, the hydraulic side cutters rotate to slice through compacted material, enhancing the pump’s ability to extract different types of debris effectively.
What are the primary uses of this dredge pump?
This type of hydraulic dredge is commonly employed in:
- Deep-sea mining for extracting mineral deposits.
- Infrastructure development, such as harbor and channel maintenance.
- Environmental remediation projects to remove contaminated sediments.
- Coastal restoration and land reclamation efforts.
What materials can this hydraulic dredge handle?
The hydraulic dredge pump with side cutters can manage various materials, including:
- Fine particles like mud and silt.
- Coarser materials such as sand and gravel.
- Dense clay, compacted soil, and submerged debris.
- Vegetative matter and anthropogenic litter.
What is the maximum operational depth of this pump?
The operational depth of a submersible dredge pump with side cutters can vary significantly with each model. Generally, these pumps are capable of functioning effectively at depths from a few meters up to 30 meters or more, depending on the specific engineering and hydraulic power available.
How should the hydraulic dredge pump be maintained?
Proper maintenance of a hydraulic dredge pump includes:
- Regular inspection and maintenance of hydraulic pumps for excavators.
- Sharpening and replacing the side cutters as needed to ensure efficient cutting performance.
- Monitoring for wear on the pump components, particularly the impeller and the suction intake.
- Checking hydraulic lines and connections for leaks and ensuring all seals are intact.
What environmental precautions should be considered with this pump?
When operating a hydraulic dredge, it’s essential to:
- Control sediment dispersion to protect aquatic habitats.
- Comply with all local and international environmental regulations concerning dredge operations.
- Implement strategies to minimize ecological impact, such as adjusting operational timing and techniques to avoid sensitive periods for wildlife.
Can this pump be used in saltwater environments?
This submersible dredge pump is built to perform in fresh and saltwater conditions. Models with enhanced corrosion resistance features suitable for harsh marine environments ensure long-term reliability and effectiveness.
What powers the hydraulic dredge pump?
The hydraulic dredge pump typically receives power from a hydraulic power unit, which can be stationed on a vessel, floating platform, or even onshore, depending on the project’s scale and accessibility.
