Weifang Jin Meng Sand Pumping Dredger Details


Our sand pumping dredger 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 sand pumping dredger 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 sand pumping dredger 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 sand pumping dredger 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.

Weifang Jin Meng Sand Pumping Dredger Other Can be Cumstomized

The sand pumping dredger can be custom made according to customers’ requirements:

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.
