Details of DMD 600-15-55KW Submersible Sand Pump for Beach Restoration at Maldivian Hotels
In the beach maintenance of Maldivian hotels, beach restoration operations have high requirements for equipment stability, wear resistance, and adaptability. The NSQ600-15-55KW submersible sand pump has become a preferred device for this scenario due to its targeted performance design. Its core information is as follows:

I. Core Technical Parameters (Adaptability to Beach Restoration Scenarios)
The parameters of this pump model have been optimized to efficiently meet the needs of fine sand recovery and accumulation correction on the beaches of Maldivian hotels. The specific parameters are shown in the table below:
Parameter Category | Specific Value | Explanation of Scenario Adaptability |
Flow Rate | 600 m³/h | The high-flow design enables rapid recovery of scattered fine beach sand, reducing sand loss caused by seawater erosion |
Head | 15 m | Adapts to the height difference between the beach and the temporary sand storage area, eliminating the need for additional high-head auxiliary equipment |
Rotational Speed | 980 rpm (revolutions per minute) | Low-speed operation reduces the impact of sand particles on the pump body and minimizes noise pollution to the hotel environment |
Power | 55 kW (kilowatts) | Sufficient power with balanced energy consumption, allowing continuous operation for a long time to meet the daily maintenance needs of the beach |
Operating Voltage | 380V, 50Hz, Three-phase | Complies with Maldivian industrial power standards, no need for additional voltage converters |
II. Core Advantages (Meeting Beach and Multi-Scenario Needs)
1. Sealing and Structure: Adaptable to Marine Environments
Adopting a mechanical seal method, it has three core advantages:
- No leakage: Prevents seawater and mortar from seeping into the pump body, avoiding moisture damage to the motor and adapting to the high-humidity and high-salinity marine environment of the Maldives;
- Easy assembly: The beach operation site has limited space, and the convenient assembly method can reduce equipment commissioning time and improve maintenance efficiency;
- Good vibration resistance: Copes with slight settlement of the soft beach ground or sea wave impact, ensuring stable operation of the equipment and reducing the risk of shutdown.

2. Material: High Wear Resistance for Extended Service Life
The flow-passing components (parts in direct contact with mortar) are made of 27% high-chromium alloy. The hardness and wear resistance of this material are far superior to ordinary steel, which can effectively resist long-term friction from fine beach sand, significantly extend the service life of the equipment in beach restoration scenarios, and reduce the cost of frequent component replacement.
3. Customization: Adapting to Different Operating Conditions
The cable length can be flexibly customized according to the specific operation scope of the Maldivian hotel beach (such as offshore distance, location of sand storage points). There is no need for additional cable splicing, which avoids equipment failures caused by loose interfaces and improves operation safety.
III. Extended Applications in Multiple Fields
In addition to being suitable for beach restoration at Maldivian hotels, this submersible sand pump can also meet the solid-liquid transportation needs of various industrial scenarios, including:
- Sewage treatment plants: Cleaning sludge and impurities in sedimentation tanks;
- Hydropower projects: Dredging sludge in reservoirs and rivers to ensure the smooth operation of water conservancy facilities;
- Mineral processing plants: Transporting tailings slurry to achieve resource recovery and environmental protection treatment;
- Coal/power industry: Cleaning coal slurry in coal yards and accumulated coal in coal conveying pipelines of power plants to ensure the stability of the production process.
