Frequently Asked Questions (FAQ)

Q1: What is the total production capacity of this submersible pump sand dredger?

A1: This electric submersible dredger features a dual mud pump setup. Each pump has a capacity of 200 CBM/H, giving the vessel a combined total flow capacity of 400 CBM/H with a maximum pump head of 30 meters, making it highly efficient for high-density sand recovery.

Q2: How does the submersible dredger loosen hard or settled sand layer?

A2: The dredging system is outfitted with 4 powerful electric agitators. Each 3kw agitator has a 400mm diameter and operates at 60 rpm to mechanically stir and agitate underwater sediment, converting it into a fluid slurry that the submersible pumps can easily extract.

Q3: What are the voltage, electrical control, and starting specifications of the pumps?

A3: The entire vessel runs on a 380V 60Hz power supply with centralized PLC control. To protect the electrical network and the 45kw pump motors, the system uses a smart "Reduce voltage start" configuration for the mud pumps, while the positioning winches leverage a "Direct start" method.

Q4: What is the size and plate thickness of the double-hull structure?

A4: The floating platform consists of 2 pontoon hulls with single hull dimensions of 9000x1750x1100mm, combining into an overall dimension of 9000x5500x1100mm. The structure is built with heavy-duty steel plates measuring 4mm for the bottom, 4mm for the sides, and 3mm for the deck.

Q5: Is a marine power generator included with the submersible sand suction dredger?

A5: The generator set is an optional component. You can purchase the marine generator independently by yourself to match your specific onsite fuel preferences and emissions standards, or request our team to provide a turnkey package.
