With submersible pumping unit
areas of application
The next type of ADST range of dredgers with submersible pump:
- Capacity by pulp – 360 m3/h
- Head from 15 up to 28 m.w.c.
They are equipped with the pumps of the APFT series.
They are designed for handling highly viscous media with a density of 1.4 kg/dm3 and ensures uninterrupted pumping of pulp with a high concentration of solid inclusions. APFT pumps can handle the slurry with hard spots with the diameter up to 60 mm. The content of solids can reach 60% by weight. These pumps are equipped with a unique patented cutter fan. Thanks to it, it is possible to ensure the permanent density of the material that is intaken, as well as to handle compressed soils with clayish inclusions.
The dredger ADST-300E can discharge 100 m3 of wet sand to the depositing site with the power consumption of the main pump of 37-55 kW.
The system of the dredger electric equipment and automation ensures all electro-technic protection measures, as well as control of current consumption and input voltage. The dredger is protected against possible heeling and water availability in bilges.
