2. How To Choose Submersible Sand Slurry Pump for River Dredging

2.1 Determining Submersible Sand Slurry Pump Requirements:

Thoroughly understanding the specific requirements of the client for the river dredging project is essential. Before recommending OCEAN Pump’s submersible sand slurry pump models to the client, our technical team carefully evaluates key parameters, including sediment discharge capacity, dredging depth, conveying distance, and the particle size of the extracted medium. A comprehensive understanding of these parameters helps us select the most suitable model and power for the client. To ensure that our recommendations meet the client’s actual needs, we rely not only on these basic dredging parameters but also engage in in-depth communication with the client to understand the specific background, goals, and potential challenges of their project. This comprehensive understanding enables us to provide more accurate and effective solutions.
Additionally, our technical team takes into consideration the potential impact of the dredging operation on the environment. We provide clients with more environmentally friendly and sustainable dredging solutions based on factors such as the geographical location of the river, climate conditions, and ecological environment.

2.2 Considering the Material of Submersible Sand Slurry pump:

It is crucial to determine whether the extracted slurry consists of sand, gravel, or a mixture of sediments. As OCEAN Pump has developed different submersible sand slurry pump products for various mediums, it is necessary to select the most suitable pump type based on the actual working conditions. For applications involving fine and soft sand, the submersible sand slurry pump model DMS is recommended. For handling sediments, the model DMZ is the preferred choice. The model DMD performs exceptionally well for extracting large particles. By matching the appropriate pump type, we aim to achieve optimal working efficiency and cost-effectiveness.

2.3 Evaluating Submersible Sand Slurry pump Efficiency and Performance:

To ensure high efficiency and excellent performance of the submersible sand slurry pump, it is important to carefully select the pump type and have a deep understanding of the flow rate, head, and efficiency data. Under the same power conditions, there is an inverse relationship between the flow rate and head: when the flow rate increases, the head decreases, resulting in a shorter conveying distance, and vice versa. The selection process should closely consider the client’s requirements and properly match the discharge pipeline, as the different pipe diameters can also affect the conveying distance.

2.4 Submersible Sand Slurry pump Design:

After careful consideration and scientific analysis, we recommend choosing OCEAN Pump’s submersible sand slurry pumps, which can operate fully submerged in water. Submersible pumps typically offer higher efficiency because they can start directly without the need for priming, eliminating the cumbersome steps during startup and reducing the risk of cavitation. Furthermore, their overall submerged design makes them more suitable for various underwater applications. In summary, OCEAN Pump’s submersible sand slurry pumps are the preferred choice in the market due to their high efficiency, convenience, and reliability.

2.5 Structure and Materials of Submersible Sand Slurry Pump

It is essential to pay attention to the structure and materials of the submersible sand slurry pump. Since these pumps typically handle abrasive sand, OCEAN Pump specifically selects a high-performance alloy material for the wet parts of the pump. This material contains Cr26 elements, which provide both wear resistance and corrosion resistance, significantly improving the pump’s durability and extending its service life.

2.6 Power Supply and Motor Requirements of Submersible Sand Slurry Pump

After a careful assessment of the existing power resources, it is necessary to select submersible sand slurry pump products that meet the electrical parameters. OCEAN Pump’s submersible sand slurry pumps are specially designed with submersible motors and equipped with 1-2 mechanical seals. Their excellent sealing performance ensures stable operation of the motor in underwater environments. The IP68 protection level of the motor further enhances operational efficiency and safety. Additionally, to optimize operational convenience and safety, OCEAN Pump also offers optional variable frequency control cabinets, which can precisely control the motor’s start-stop function and enhance circuit protection, ensuring the safety of the operators.

2.7 Maintenance and Repair of Submersible Sand Slurry Pump

Look for submersible sand slurry pumps that are easy to maintain and repair. Check for readily available spare parts and consider the manufacturer’s reputation for customer support and after-sales service. In the long run, pumps with easily removable components and user-friendly designs can save time and money.

2.8 Considering the Total Cost of Ownership

While the initial purchase price of the submersible sand slurry pump is a key consideration, the total cost of ownership over the entire lifecycle should not be overlooked. This includes evaluating energy efficiency, maintenance requirements, and expected durability, among other factors. It is worth noting that high-quality pumps may come with a higher initial investment, but they often reduce long-term operating costs and minimize unplanned downtime. OCEAN Pump is committed to producing high-quality submersible sand slurry pumps, ensuring product quality, and providing customers with the best discounts and excellent after-sales service.

3.Successful Cases in Nigeria

In June 2022, Lingda Kong, an outstanding sales representative from OCEAN Pump (contact: WhatsApp +86 185 6229 3317), received a Nigerian client from Guangzhou. The purpose of the client’s visit was to assist their Nigerian friend in purchasing a Submersible Sand Slurry Pump. Prior to the visit, Lingda Kong had already communicated extensively with the client to understand their specific requirements. Therefore, the client’s visit aimed to assess the manufacturing capabilities of our company, OCEAN Pump, and validate the operational parameters and efficiency of the Submersible Sand Slurry Pump through on-site testing.

Upon the client’s arrival, to ensure accurate selection, Lingda’s team engaged in in-depth discussions with the client regarding the actual working conditions and detailed requirements. The client needed to extract fine sand from a river with a flow rate requirement of 400 cubic meters per hour, a target sand output of 80 cubic meters per hour, and a sand pumping distance of 220 meters. Taking these factors into consideration, as well as the client’s existing 8-inch HDPE pipeline and generator set on-site, our engineer salesperson Lingda (contact: WhatsApp +86 185 6229 3317) recommended the DMZ400-15-37 Submersible Sand Slurry Pump. To ensure operational safety, we also suggested the client equip a frequency control cabinet to optimize the motor start-up process. This solution not only fully met the client’s requirements but also made full use of their existing generator resources.

Furthermore, since our workshop happened to have the same model of Submersible Sand Slurry Pump available, and OCEAN Pump possesses a pump testing platform, we provided on-site testing services to the client. The testing results were highly satisfactory, exceeding the client’s expectations. The client expressed great satisfaction and immediately made a deposit, requesting us to promptly manufacture a brand-new Submersible Sand Slurry Pump. Five days later, we sent the client a video of the pump’s testing, and the client was pleased with the data. Subsequently, with the assistance of the recommended shipping agent by OCEAN Pump, the product quickly arrived in Nigeria. The client provided feedback stating that the performance met their expectations and highly praised the professional knowledge and pre-sales and after-sales services provided by our engineer salesperson Lingda (contact: WhatsApp +86 185 6229 3317).
