Our company's submersible dredging pump for 25m depth cutter suction dredger machine, is equipped with a special underwater pump. This ship is self-propelled or non-self-propelled, which is particularly convenient to move. The hull is made into a structure that can be disassembled and packed, and then assembled on site. After disassembly, it can be transported by truck, train or container, so it is very easy to install or change work. The power used on the ship can be designed according to actual needs, and can be electric or diesel engine. In addition to this underwater pump, the ship also has equipment responsible for left and right movement, equipment for controlling the lifting and lowering of the sludge suction pipe, piles for fixing the ship's position, and a small crane installed on the deck.
The working process is as following: the cutter head cut the sand and mud underwater to mixture of slurry, then through dredging pump to the pipeline on cutter suction dredger with submersible pump; at the end the slurry will be discharged by pipeline on land to the required place.

This cutter suction dredger with submersible pump is relatively short and can easily drill through the low bridge on the river. The cab and lounge on the ship can be removed for easy transportation. The entire hull is composed of three pontoons, one large and two small, which are assembled together with special connectors and then tightened with super strong screws. The connection between the cabin and the deck also uses a live buckle, which is particularly convenient for disassembly and assembly. In general, this design makes it very easy to move and assemble the entire ship.
Working site of cutter suction dredger with submersible pump: sea, port, lake, and river. Soil conditions: relative hard soil, harden sand, sludge, sea sand, river sand, clay, mud, and so on.
Design
Our cutter suction dredger with submersible pump is designed by senior engineer, who have specialized in shipbuilding and dredging work for many years, to guarantee they are well-designed and practical.
Cummins Engine
The cutter suction dredger with submersible pump is equipped with world famous powerful Cummins engine, which are famous for its durability, lower oil consumption, standardized accessories and easy maintenance.
Hydraulic system
The most important parts of cutter suction dredger with submersible pump and wheel bucket dredger. The hydraulic system requirements are very high and strict; it’s the main artery of the entire dredger. Lateral traction winches, lifting winch and cutter head of the dredgers are driven by hydraulic motors.An integral hydraulic system includes hydraulic oil tanks, hydraulic pump, hydraulic valve manifold, solenoid valve, hydraulic pipes, hydraulic components, electrical actuator and so on.
Detachable Structure
The cutter suction dredger with submersible pump is detachable, so it is easy to transport when delivering or moving from one working site to another.
Shijiazhuang Pump
Flow passage components use High wear resistant alloy Cr27 to prolonged the pump service life, pump shaft seal use packing seal which is easy to maintain , and anti-friction bearings are from Japanese brand NSK.
Cutter head
For one cutter head, there are 5 blade, 8 teeth equipped on one blade. There is material High chromium. for easy-wearing proof.Cutter head is driven by hydraulic motor; cutter bearing has lubrication seal-in units.
1. Anchor booms installation
2. Spud carriage
3. Dredger position of 5 anchors.
4. Hydraulic driving for spud flat down(to pass low bridge and transportation on water safely).
5. Make the dredger with extra dredging pump underwater to deepen dredging depth for 20-30m underwater and slurry concentration is more than 30%.
6. Make the dredger with booster station to further the discharge distance.
