3. How to Choose Submersible Dredging pump

Choosing the right submersible dredging pump is critical to ensuring an efficient and effective dredging operation. Here is the ultimate guide to help you make an informed decision when choosing a submersible dredge pump:

1. Clarify your dredging needs

First, fully understand your dredging needs. Consider factors such as the type of material to be dredged (e.g., sand, silt, mud), solids concentration, required pumping capacity, and the distance and height over which the material will be pumped. Through in-depth investigation of the customer’s working environment, OCEAN Pump can accurately tailor the most suitable solution for the customer. Understanding the actual conditions at the dredging site helps ensure that the selected submersible dredging pump can operate stably in a complex working environment and can handle various materials efficiently, ensuring that the provided submersible dredge pump configuration is in terms of performance and efficiency. can reach the best level.

2. Consider the size and power of the Submersible Dredging Pump

When selecting a submersible dredging pump, its size and power must be carefully considered. In order to ensure that the pump can effectively cope with the challenges of dredging operations, it needs to be ensured that it has sufficient capacity and power. In addition to this, we thoroughly evaluate key parameters such as flow, head and required pressure to ensure that the selected pump will fully meet the specific application requirements. What is trustworthy is that the OCEAN Pump design team has a profound professional background. They can accurately calculate the required power configuration based on the flow and spacing parameters provided by the customer, thereby providing customers with customized solutions.

3. Solids Handling Capability

To evaluate the solids handling capabilities of a submersible dredge pump, look for a pump that can effectively handle the solids sizes and concentrations found in dredging applications.
First, OCEAN Pump considers the pump’s impeller design for customers, because the shape and structure of the impeller directly affects the solids handling capacity of the pump. Proper impeller design should be able to effectively agitate and transport solid particles of various sizes and shapes, ensuring that they do not accumulate within the pump or cause blockage.
Secondly, in practical applications, the clearance design of the pump needs to be adjusted according to different working environments and medium characteristics. For example, for media containing larger particles, the gap design must be relatively large to prevent particles from getting stuck in the internal parts of the pump, causing the pump to fail to work properly. On the contrary, for media handling finer particles, the gap design must be relatively small to ensure smooth operation of the pump.
OCEAN Pump fully considers these factors when designing the gap, allowing its products to maintain efficient operation when handling solid particles of different sizes. Moreover, reasonable clearance design can also effectively reduce the wear of the pump and extend the service life of the pump.

3. Material Structure

When looking at the structural materials of a submersible dredge pump, we need to look for materials that are both durable and resistant to corrosion, wear and erosion. Common ones include stainless steel, high chromium alloys, and other special coatings or linings, which can greatly increase the service life of the pump in harsh environments. The submersible dredge pumps produced by OCEAN Pump use a variety of materials and can be customized according to customer needs. Among them, the commonly used material for flow-passing parts is Cr28. This material has a certain degree of corrosion resistance and its main feature is wear resistance. It is a commonly used material for flow-passing parts of submersible dredging pumps. In order to ensure product quality, OCEAN Pump uses professional material measurement tools to test each part before the product leaves the factory.

4. Efficiency and energy consumption

Evaluate the efficiency and energy consumption of the pump. Look for pumps that focus on high-efficiency designs designed to minimize energy losses and reduce operating costs. Factors such as impeller design, hydraulic efficiency, and motor efficiency all need to be considered for optimization. OCEAN Pump has a professional clean water testing platform equipped with a complete clean water performance testing system, which can comprehensively evaluate the performance of the pump. Through this platform, we can accurately measure key indicators such as pump flow, head, and efficiency to ensure that the pump performs as expected in actual application scenarios. In addition, we can also optimize the pump design based on test results to further improve pump performance and efficiency.

5. Submersible Depth Rating

Determine the required submersible depth rating of the pump. Ensure the pump can operate at the required depth without compromising performance or safety. Consider factors such as cable length, sealing mechanisms and submersible motor design. Sealing technology is crucial. In order to improve sealing performance, technologies such as double-end mechanical seals and floating seals can be used. The double-end mechanical seal can effectively prevent medium leakage and improve the working efficiency of the pump; while the floating seal can adapt to the pressure changes experienced by the submersible pump in the deep sea and ensure the normal operation of the pump.
In addition, cable selection is also key. To ensure the safety and reliability of cables, cables that are waterproof, UV-resistant, and abrasion-resistant should be selected. In addition, the cross-sectional area and length of the cable also need to be determined according to actual working conditions to avoid overheating or damage to the cable.
For deep submersible pumps, the design of the motor is particularly important. In order to withstand deep sea pressure, the motor should have high strength and pressure resistance. In addition, the motor should have good heat dissipation properties to prevent overheating. In this regard, OCEAN Pump uses advanced motor design technology to ensure stable operation of the motor in deep water.

6. Pump control and monitoring

When selecting a submersible dredging pump, in addition to paying attention to its basic performance parameters such as flow, lift, power, etc., you also need to evaluate its optional control and monitoring functions. An ideal submersible dredging pump should have protection mechanisms such as remote control, monitoring system, overload protection, temperature monitoring, and vibration sensors. These functions can improve operational safety while achieving intelligent management and optimized operation of the pump.
The DMD submersible mud pump designed by my country’s well-known brand OCEAN Pump has set a good example in this regard. It is equipped with advanced functional modules such as WC (thermal protection core wire), XL (water ingress protection core wire), YS (oil and water probe core wire). These modules can achieve comprehensive protection of the pump and ensure its stable operation in complex environments.
Likewise, submersible mixers are designed with operational safety and efficiency in mind. It is equipped with WC (thermal protection core wire), XL (water inlet protection core wire) and other protection circuits, which can monitor various parameters in real time during use to ensure the normal operation of the submersible mixer.
In practical applications, the control and monitoring functions of submersible dredging pumps and submersible mixers play an important role. For example, when the pump or mixer experiences abnormal conditions such as overloading, abnormal water inflow, oil-water mixing, etc., the system can immediately issue an alarm and cut off the power supply in time to prevent equipment damage. At the same time, through temperature monitoring and vibration sensors, the operating status of the equipment can be understood in real time and remotely controlled and maintained, greatly improving the reliability and service life of the equipment.
