A Cutter Suction Dredger (CSD) is a stationary dredging vessel that excavates soil, sand, clay, or rock underwater using a rotating cutter head, suction the dredging material through suction pipe, transferring the dredging product through pipeline by pressured sand dredge pump powered by diesel engine or electric motor. It combines three key functions:
Cutting: A rotating cutter head (equipped with blades/teeth) loosens hard material.
Suction: A powerful centrifugal pump sucks the loosened material (slurry) through a pipe.
Disposal: The slurry is transported via pipelines to barges, reclamation sites, or designated disposal areas.

Cutter Suction Dredgers (CSDs) are stationary dredging vessels renowned for their precision, versatility, and efficiency in excavating underwater terrain. Unlike trailing hopper dredgers, CSDs anchor themselves via spud poles and swing laterally to cut material within a defined arc.

A jet suction dredger is a highly specialized piece of equipment used for dredging operations. It plays a crucial role in various marine and inland waterway projects. By utilizing the power of high - pressure water jets and suction mechanisms, it can efficiently remove sediment, debris, and other materials from the bottom of water bodies.

A jet suction dredger is a specialized piece of marine equipment designed to remove sediment, debris, and other materials from the bottom of water bodies such as rivers, lakes, ports, and seas. It operates on the principle of using high - velocity water jets to loosen and fluidize the sediment, which is then suctioned up through a pipeline and transported to a designated disposal area.​

Submersible Slurry Dredge also called submersible slurry pump dredger, is designed and manufactured with optimized hydrodynamics technology for sand dredging and silt clearing.Our submersible dredge pump and the suitable pontoon, especially the remote control made everything easily.

Amphibious multifunctional dredger,including amphibious type and amphibious with crawler type, mainly applied for shallow waters, lakes, rivers, canals, ponds and basinscapital dredging.It is equipped with replaceable working units such as excavating bucket, dredge pump, water weed cutter, collecting rake and T-type cutter.

Sand dredge pumps are engineered to handle highly abrasive mixtures with efficiency and durability. Key characteristics include:- Centrifugal Design: Utilizes centrifugal force to move sand and slurry at high speeds.- Heavy-Duty Construction: Built to withstand harsh dredging environments.

ITECH Electric Heavy Duty Submersible Dredge Pump with 2 Cutterheads is specifically designed for high-efficiency material removal in harsh dredging conditions. Powered by an electric motor, this submersible dredge pump features two integrated cutterheads that rotate to break up compacted materials and allow for easier pumping of thick slurries and sediments. 

​ITECH Electric Submersible Dredging Pump with Side Agitators features a robust electric motor that provides consistent, energy-efficient power. The integrated side agitators stir up settled sediments and materials, ensuring that they remain suspended in the water, ready for easy transfer by the pump. This design prevents clogging, maximizes pump performance, and reduces maintenance time.

ITECH Electric Agitator Dredging Pump integrates a powerful electric motor with an agitator that mixes and suspends sediment to create a homogenous slurry. This design allows for the movement of dense materials without clogging, making it a perfect solution for dredging tasks that involve thick or compacted sediments.

​ITECH Electric Submersible Dredge Pump is a robust and compact pump designed for submersible dredging in both shallow and deep-water environments. Powered by a reliable electric motor, it is designed to pump large volumes of water with high solid content, including sand, silt, gravel, and mud.

​ITECH Electric Slurry Pump with Cutters combines powerful electric motor performance with an aggressive dual-cutter head system. The cutters are mounted around the pump inlet, rotating at high speed to break down compacted material, loosen sediments, and ensure uninterrupted slurry flow into the impeller.
