It is crucial for the customers to choose economically reliable and easy to maintain sand extraction equipment when carrying out sand mining operations. This article introduces the main river sand pumping equipment and its characteristics of OCEAN PUMP, and provides practical cases for customers to choose from. Understanding the performance and characteristics of different machinery can help to ensure the smooth progress of sand pumping work. Through the practical cases, you will be able to make wise decisions in the selection process to meet the specific needs of river sand extraction or river dredging.
1. What river sand pumping equipment does OCEAN PUMP mainly produce?
OCEAN PUMP specializes in designing and manufacturing efficient and reliable sand dredging products. The products mainly include horizontal sand pumps, vertical sand pumps, submersible sand pumps, various types of dredgers, pipelines, and related accessories. These mechanical products aim to effectively extract and clean sediment, mud and sand slurry, and debris from rivers, lakes, ports, and other water bodies. OCEAN PUMP's pumps and sand dredging equipment are renowned for their high performance, durability, and versatility, making them the preferred choice for river sand pumping and dredging projects.
2. Should the river sand mining project start from the pump unit or from the dredgers?
2.1 What are the main types and characteristics of OCEAN PUMP sand pumps?
OCEAN PUMP sand pumps are all centrifugal sand pumps, mainly including horizontal sand pumps, vertical sand pumps, and submersible sand pumps.
Horizontal sand pump:
The horizontal sand pumps are usually placed in the cabin of the dredger. And the sand pumps are driven by horizontally placed diesel engine or motor.
Horizontal sand pumps are usually mechanically operated, with stable performance, easy maintenance, and low failure rate.
Vertical sand pumps:
The vertical sand pumps are commonly used for sand unloading ships and dredging operations in waterways. The top of the vertical pump is connected to the motor, and the pump's inlet is directly immersed in the liquid for operation. Its characteristics are low cost and flexible operation.
Submersible sand pump:
The pump and motor of the submersible sand pump are coaxial and integrated. When working, the entire pump body is submerged in deep water, and the motor casing and cables need a high waterproof level.
The submersible sand pump has a wide range of uses, and with technological progress, The submersible sand pump of OCEAN PUMP can reach dredging depth of 150 meters underwater, which is a challenging working area for horizontal sand pumps. In addition, the working environment of the submersible sand pump is clean, with low noise and easy operation, which is favored by more and more customers.
2.2 Sand pump and sand dredger.
The dredging pump is an important component of sand mining operations. It is specifically used for extracting and transporting sediment, silt, and other substances from water bodies. Dredging pumps are usually installed on floating platforms or connected to suction arms, allowing them to reach the bottom of the water and extract materials from the bottom of the water. Then the extracted material is pumped through a pipeline to the designated discharge area.
On the other hand, a complete set of dredgers refers to a complete system that includes not only dredging pumps but also other important components. This includes the hull or vessel, power sources, dredging mechanisms (such as cutter suction heads), and auxiliary equipment such as piles, anchors, and pipelines. Dredgers use dredging pumps and these components to excavate, transport, and deposit dredging materials.
The dredging pump is mainly responsible for suction and pumping, and the complete set of dredgers provides a more comprehensive solution for dredging engineering. It combines various functions into one system, providing greater versatility and efficiency. Sand dredgers can handle larger volumes of materials, navigate and locate in water bodies, and perform more complex dredging tasks such as cutting and compacting sediment.
2.3 How to make a choice for dredging equipment?
Ordinary users develop their own equipment procurement and maintenance plans based on their own experience, and usually do not raise this issue. However, new clients often encounter budget constraints during the initial stages of a project. Some people may consider starting with a basic pump unit, placing the sand pump on the shore, and manually operating the sand suction head. However, this method has drawbacks such as low efficiency, limited operating range, and is not suitable for deep and wide river operation areas.
Therefore, selecting appropriate sand dredging equipment is a more effective method for large-scale river sand pumping projects. This allows for effective work execution and fast sand recovery, ensuring optimal project results.
3. What is the most popular model of sand dredger in Africa?
3.1? Jet Suction Dredger
Jet suction dredger is the most popular dredging machinery for river dredging produced by OCEAN PUMP. The working principle of a jet dredger is to use a high-pressure water pump to provide high-pressure water and flush sediment through a high-pressure water gun. After high flow of water, rinse the deposited sediment with water. We use sand pumps, mud pumps, and gravel pumps to extract sand and water, and then transport them to the destination through sand discharge pipes and sand dredger floats. This type of dredging machinery plays an important role in river dredging, port dredging, coastal reclamation, and sand pumping and filling projects.
3.2? Submersible Pump Dredger
However, with technological innovation, SUBMERSIBLE PUMP DREDGER is increasingly favored by customers. The main advantages of submersible sand pumps include the following:

4. Successful cases:
A Cameroonian customer wants to order a sand pumping dredger to extract river sand from the river. The dredging depth is about 5-15 meters, requiring 100-150 cubic meters of sand per hour, and the discharge distance is about 300 meters. Based on these data, we recommended SSD500-25 Submersible pump dredger and JSD250 jet suction dredger to our customers. The SSD500-20 dredger is equipped with a ZJQ500-25-90 submersible sand pump, while the JSD250 dryer uses a horizontal sand pump.
In the process of communicating with the client, we learned that the client has the ability to weld the hull of the dredger on their own. This can greatly save transportation costs. Considering the simpler hull structure of the submersible pump dredger, as the customer's first self-welded sand dredger, it will be easier to get started with the Submersible Pump Dredger.
After communication and discussion, we provided all accessories except for the dredger hull to the customer. Mainly including sand pump, high-pressure water pump, generator set, control cabinet, cable reel, winches, sand discharge pipeline and pipe floaters, etc.
Technical parameters of dredging machinery:
Sand Pump:? ZJQ500-25-90 submersible slurry pump
Sand pump flow rate: 500 m 3/h
Pump head: 25 meters
Dredging depth:? 5-15 meters
Discharge distance: 300-500 meters
Water pump power: 18.5KW
Lifting winch: 15KW
Anchor winch: 5.5KW
Generator: WEICHAI 200KW generator set
Discharge pipe: 10 Inch HDPE pipe
After receiving the product, the customer quickly assembled the sand pumping boat with our technical guidance and the efforts of their team. And after several trial runs, I proficiently mastered the operating skills of the Submersible Pump Dredger, achieving a satisfactory output.
5. Conclusion:
Choosing the appropriate dredging machinery is crucial for sand mining, mining, or river dredging. This article introduces OCEAN dredging products and their characteristics, and provides practical cases for customers to choose from.
