A hydraulic submersible sand dredger is an advanced dredging system designed for efficient sand extraction, sediment removal, and slurry transfer in rivers, lakes, ports, and construction sites. With compact structure, high pumping efficiency, and flexible mobility, it has become one of the most preferred solutions for contractors and mining operators worldwide. Among the top manufacturers in China, ITECH Co., Ltd. delivers dependable and custom-built hydraulic submersible sand dredgers that meet global standards for performance and durability.
A hydraulic submersible sand dredger combines a powerful hydraulic-driven submersible pump with flexible operating systems. Unlike electric models, the hydraulic version uses hydraulic power packs and oil-driven motors to generate strong suction underwater. This design ensures high reliability, excellent wear resistance, and smooth performance even under heavy sand conditions.
This type of dredger is ideal for:
Sand mining and riverbed cleaning
Port and harbor dredging
Land reclamation and beach nourishment
Mining slurry transportation
Construction and foundation engineering
ITECH dredgers deliver exceptional sand pumping capacity with stable hydraulic pressure. The submersible pump can operate at depths up to 30 meters, ensuring steady sand extraction without clogging or cavitation.
All critical parts — impeller, casing, and suction plate — are made from high-chromium alloy steel, providing outstanding wear resistance and extended service life in abrasive environments.
The hydraulic submersible sand dredger can be installed on excavators, cranes, or floating pontoons, allowing quick deployment at different work sites. It’s ideal for mobile dredging operations and confined water areas.
Hydraulic systems minimize mechanical wear, reducing the frequency of maintenance. The pumps are designed for continuous heavy-duty operation, even in high-solid-content mixtures.
ITECH engineers design customized configurations for flow capacity, discharge distance, power rating, and material composition, ensuring the best performance for each project.

Q1: How does a hydraulic submersible sand dredger work?
A: The hydraulic system drives the submersible pump, which sucks up sand and slurry from the bottom and transports it through a discharge pipeline to the designated area.
Q2: What power source does it use?
A: Typically, a diesel engine hydraulic power pack is used to generate hydraulic flow, which powers the submerged pump.
Q3: Can it be attached to an excavator?
A: Yes, ITECH hydraulic dredgers can be mounted directly onto excavator arms, turning them into highly efficient sand extraction machines.
Q4: What materials can it handle?
A: It’s designed to handle sand, gravel, mud, and slurry with high solid concentrations.
Q5: What’s the delivery time?
A: Depending on customization, production and delivery take 45–90 days, with fast shipping options available.
