12 Inch Submersible Pump Dredger

The 12 inch submersible pump dredger is designed with a submersible pump that is placed directly into the water to suction and transport sand. This type of dredger is particularly useful for operations where space is limited or where the dredging area is difficult to access,the worksite with noise restriction, or some deep water area.
  • Product Structure: It features a submersible pump that is submerged in the water, connected to a flexible suction pipe. The pump is powered by an electric motor or a diesel engine, and the sand is transported through the pipe to the discharge point.
  • Applicable Working Conditions: Ideal for confined spaces, such as small harbors, canals, and ponds. It is also suitable for operations where the dredging area is surrounded by structures or other obstacles that make it difficult to deploy larger dredging equipment.
  • Parameter Range: The dredging depthcan be customized up to 150m, and the dredging capacity can range from a few hundred cubic meters per hour to over a thousand cubic meters per hour. The discharge distance is generally shorter compared to other types of dredgers, but it can still be effective for short to medium distances.
  • Price Range: The cost of a 12 inch submersible pump dredger can vary depending on the brand and features. Prices generally range from $40,000 to $200,000.
  • Dredging Depth: For operations requiring dredging depths exceeding 20 meters, the Ocean Pump SPD Series Submersible Pump Dredgercan be considered. These custom-designed dredgers are built to meet the specific needs of deep-water dredging projects.

Factors Influencing the Price of 12 Inch Sand Suction Dredgers

The price of a 12 inch sand suction dredger is influenced by several factors, including the type of dredger, its product structure, and the specific requirements of the dredging project. Here are some of the key factors that can affect the cost:

Product Structure and Design

Different types of dredgers have varying levels of complexity in their design and structure. For example, a cutter suction dredger with a more advanced cutting head and hydraulic system will generally be more expensive than a simpler jet suction dredger.

Dredging Depth

The maximum dredging depth that the dredger can achieve is a significant factor in determining its price. Dredgers capable of deeper dredging operations require more powerful pumps and stronger structural components, which increases their cost. For example, the Ocean Pump JSD Jet Suction Dredger can be designed for depths up to 25 meters, while the Ocean Pump OPCSD Cutter Suction Dredger is typically limited to 14 meters. Custom solutions for depths exceeding 20 meters, such as the Ocean Pump SPD Series Submersible Pump Dredger, can significantly increase the cost due to specialized design and engineering requirements.

Discharge Distance

The distance over which the dredged material can be discharged also affects the price. Longer discharge distances require more powerful pumps and additional equipment such as booster pumps, which can significantly increase the cost of the dredger.

Elevation Difference

The elevation difference between the dredging area and the discharge point can impact the cost. A higher elevation difference requires more powerful pumps to transport the sand, leading to an increase in the overall cost.

Pipeline Layout

The layout and length of the discharge pipeline can also influence the price. More complex pipeline layouts, such as those involving multiple bends or long distances, require additional materials and engineering, which can add to the cost.

Water Flow Speed

The speed of the water current in the dredging area can affect the efficiency and performance of the dredger. Dredgers designed to operate in areas with faster water currents may require more robust and specialized components, which can increase their cost.

Sand Layer Structure

The structure and composition of the sand layer being dredged can also impact the cost. Dredging harder or more compacted sand requires more powerful cutting and suction systems, which can increase the cost of the dredger.

Conclusion

The cost of a 12 inch sand suction dredger can vary widely depending on the type of dredger, its product structure, and the specific requirements of the dredging project. Jet suction dredgers are generally more affordable and suitable for loose sand slurry operations, while cutter suction dredgers offer more versatility and can handle deeper dredging depths and more challenging sand conditions. Submersible pump dredgers are ideal for confined spaces and can be a cost-effective solution for certain types of dredging projects. When selecting a 12 inch sand suction dredger, it is important to consider the specific needs of the project, including the dredging depth, discharge distance, elevation difference, pipeline layout, water flow speed, and sand layer structure, to ensure that the chosen dredger is both effective and cost-efficient. The Ocean Pump JSD Jet Suction Dredger, Ocean Pump OPCSD Cutter Suction Dredger, and Ocean Pump SPD Series Submersible Pump Dredger provide a range of options to meet different dredging depth requirements, from shallow to deep-water operations.
