Plain Suction Dredger

Electric Pump Drives with Water-Jet Assistance

Planning sediment removal starts with matching equipment to your site, not selecting a flow figure alone. This plain suction dredger from Shandong Wanrun Intelligent Equipment Co., Ltd. combines electric pump drives with a separate water-jet assistance system.

Key Features for Sediment Removal

Separate pumping duties:

• The dredge pump handles sediment transport, while the jet-water pump supplies water to loosen material around the intake.

Electric pump drives:

• The specified 250 kW dredge-pump motor and 90 kW jet-water-pump motor use variable-frequency starting for controlled startup.

Dedicated winches:

• One lifting winch and three traversing winches support intake handling and repositioning during dredging operations.

Overload protection:

• The control specification includes overload protection to help safeguard electrical circuits.

How This Plain Suction Dredger Works

The configured water-jet system loosens sediment before it enters the suction intake. The 350PNS-35 dredge pump then moves the water-and-sediment mixture through the discharge pipeline. These are separate functions: the jet-water pump assists loosening, while the dredge pump provides transport.

The production specification lists a central machinery compartment, side pontoons, a lifting arrangement and an operator cabin. It also specifies variable-frequency starting for both pump motors. Final layout, power supply and operating arrangements should be confirmed for the project.

When evaluating a plain suction dredger, provide sediment samples or grading data rather than relying on a general material description. Compaction, particle size, debris and site geometry need engineering review before equipment suitability or output can be confirmed.

Plain Suction Dredger Reference Specifications

The figures below describe the supplied production configuration. They are reference values, not guaranteed results for every operating condition.

Important: The 1,800 m³/h figure is clear-water flow, not sand production or solids throughput. No verified solids production rate is provided in the source specification. Dredging depth, conveying distance and flow must not be assumed achievable simultaneously at their listed values.

All data are for reference. Final specifications shall follow drawings approved by the relevant ship inspection authority. This condition does not establish that approval has already been obtained.

Configuration Basis

This plain suction dredger description is based on a manufacturer-supplied production specification rather than estimated performance claims. The document identifies the pumps, motor ratings, winch arrangement and fabrication details. Request the final configuration and approved drawings during technical review.

Discuss Your Dredging Project

To assess this plain suction dredger for your site, send Wanrun your sediment type, dredging depth, pipeline length and elevation difference. Include the required solids output, available electrical supply, access restrictions and operating conditions. These inputs support a project-specific proposal instead of an unsupported capacity promise.

Frequently Asked Questions

Does this configuration include water-jet assistance?

Yes. It specifies a separate 200-150-400 water pump with a 90 kW motor to help loosen sediment. The dredge pump has its own 250 kW motor.

Is 1,800 m³/h the sand production capacity?

No. It is the listed clear-water flow of the dredge pump. Solids throughput requires a separate assessment of material, concentration and the pipeline system.

Are the 20 m depth and 500 m conveying distance guaranteed together?

No simultaneous operating guarantee is established by the supplied document. Both values require confirmation against the final drawings and project conditions.

What power supply does the equipment require?

The configuration specifies electric motors, but it does not state voltage, frequency or a complete connected-load schedule. Confirm the site supply and total electrical requirements before ordering.

What information is needed for a quotation?

Provide the sediment characteristics, target solids output, working depth, pipeline route and power availability. Wanrun can then review the reference configuration against your project requirements.
