Description :
 

The dredger with an APFT submersible dredge pump, the pulp capacity of which is 200 m3/h and the head reaching from 15 till 28 m.w.c.

ADST-200E is designed for:

  • Excavation of 1-3 categories’ soils;
  • Recovery of sand and other non-ferrous materials;
  • Aggradation of dikes, roads, construction sites;
  • Dredging operations.

Thanks to the application of submersible pump as soil intake technology without suction pipeline, it is possible to extract and handle the pulp with the concentration of solids up to 60% by weight and sand output up to 30% of nominal capacity.

This dredger can extract 50 m3 of wet sand to the depositing site with the power consumption of the main pump of 22-37 kW.

Dredger power supply - three-phase, from the shore 400 V grids.

The dredger is equipped with a water jet system comprising a centrifugal pump and a jet ring with nipples mounted directly on a dredge pump. The jet pump creates the pressure of minimum 8 bars which are sufficient to loosen compressed soils with clayish inclusions. This technology makes it possible to continuously pump water-sand mixture with the density up to 1.4 kg/dm3. Thus, hydraulic excavation operations are carried out with high efficiency.

The dredger construction is designed as trimaran with the installation of the dredge pump at the suspension at the forepart of pontoons. Lifting and submerging of the pump is carried out by means of winch through gantry with a block mechanism. This dredger can reach the excavation depth of 30 m. The dredger is compact, plan dimensions are 9.5 x 5 m. The height of the pontoons is 1 meter. The dredger has got a modular design, thus, it can be transported by trucks. To assemble a dredger, 1-2 days are sufficient.

The dredger maneuvering within the water body is anchor-rope by means of mooring winches installed in the corners of a dredger.

If necessary, the dredger can be equipped with discharge pipelines from PE, power cable, and steel pontoon-type floaters.
