2. Why Submersible Sand Slurry Pump is used for Dredging Works

2.1.The Submersible Ability of Submersible Sand Slurry Pump

The unique design of the Submersieble Sand Slurry Pump allows it to be completely submersed in water and operate directly in the dredging area without the need for additional equipment such as suction pipes or starting systems. This simplifies the operation process and is suitable for both shallow and deep water environments. OCEAN Pump’s Submersieble Sand Slurry Pumps are available in both electric and hydraulic drive options.

The electric drive pump shaft and motor are integrated in design, using a special submersible motor with an IP68 waterproof rating to ensure stable operation in high water pressure environments. At the same time, OCEAN Pump equips the motor with a frequency conversion control cabinet and multiple protection circuits, such as oil chamber water intrusion protection, motor water intrusion protection and temperature load protection, etc., all based on the summary of years of communication experience with customers.

The hydraulic drive method is suitable for installation on excavators, replacing the bucket, and is directly driven by the excavator’s hydraulic pump station, and the pump body can be completely immersed in the liquid. Both driving modes realize the overall submersible operation of the pump body, and the pump port is in direct contact with the slurry, thus improving operating efficiency and output.

2.2 Solid Handling Capacity of Submersible Sand Slurry Pump

The dredging work of the Submersible Sand Slurry Pump involves removing sand, silt, sediment and other solid materials from the water body. For the effective treatment of these sharp, sticky or corrosive materials, OCEAN Pump has specially designed a Submersible Sand Slurry Pump made of special materials. Through years of design experience, we have optimized the size of the impeller to ensure that the Submersible Sand Slurry Pump has a sturdy and durable structure. The use of wear-resistant materials and special impellers can effectively prevent clogging and damage caused by the presence of solids.
When selecting the material of the flow-passing parts, OCEAN Pump prefers to use Cr26 material. This is because this material is a commonly used wear-resistant material for sand pumps. The Cr content is not less than 26%, the hardness HR ≥ 65, and it also has certain corrosion resistance. This makes Cr26 an ideal choice for the wetted parts of Submersible Sand Slurry Pumps.
In addition, we have designed two different types of impellers according to the different working conditions required by customers: semi-open and closed. Semi-open impellers are suitable for scenarios requiring large flow rates, while closed impellers are more suitable for working environments requiring high pressure. This flexible structural design is designed to meet the specific needs of different customers.
It is worth mentioning that our Submersible Sand Slurry Pump can pump media with a particle size up to 60mm. In order to meet higher concentration processing needs, OCEAN Pump also provides customers with side cutter or high-pressure water gun as options, which can increase the working concentration to 60%.

2.3. High efficiency of Submersible Sand Slurry Pump

The unique design of the Submersible Sand Slurry Pump is that the pump body is in direct contact with the slurry, which eliminates the need to consider cavitation and vacuum suction lift issues when working. This design not only simplifies the operation process, but also improves the overall efficiency of the pump. In addition, the Submersible Sand Slurry Pump works below the water surface. In this way, the distance below the water surface can save the height of the lift, further improving the efficiency of the pump.
In order to further increase the concentration of extraction, OCEAN Pump specially designed a flushing system and a stirring system. The flushing system uses a high-pressure water gun to fully mix the slurry in the water through the high pressure of the water gun. This mixing process not only distributes the solid particles evenly in the liquid, but also increases the concentration of the draw. The mixing system further improves the concentration by adding 2 or 3 agitators to fully stir the slurry. This dual system design gives Submersible Sand Slurry Pumps excellent performance when handling fluids with high solids content.
In addition to the above design features, OCEAN Pumps also pays attention to the size and shape design of the impeller and volute. By precisely controlling the size and shape of these critical components, Submersible Sand Slurry Pumps ensure optimal flow dynamics. On the premise of ensuring efficiency, the flow rate and head are increased, and large particle materials can also be passed. This design not only reduces energy loss, but also maximizes the hydraulic performance of the pump. This optimized hydraulic design makes the Submersible Sand Slurry Pump more efficient and has a longer service life when transporting fluids containing solids.

2.4  Mobility and Operability of Submersible Sand Slurry Pump

The design features of Submersible Sand Slurry Pumps enable them to demonstrate excellent mobility and practicality in dredging projects. Compared with the traditional horizontal pump, its ideal working state needs to be supported by a platform and is preferably located below the water surface; if it is placed above the water surface, it must be filled with water. The Submersible Sand Slurry Pump is unique and equipped with a sturdy lifting fixing frame, so that it can be easily hoisted and directly sunk into the water, which greatly improves the convenience of its hoisting and movement.
During operation, the Submersible Sand Slurry Pump demonstrated excellent performance. It produces extremely low noise during operation and effectively maintains the stability of the water surface. In addition, OCEAN Pump is equipped with advanced frequency conversion control cabinets for each pump. This control cabinet can not only conveniently control the start and stop of the pump, but also integrates water ingress protection and overheating protection functions to ensure the safety of operators. It is worth mentioning that by adjusting the frequency, users can also easily adjust the flow rate and head, achieving precise control of pump performance. The entire operation process is intuitive and simple. You only need to operate the control cabinet to start and stop the pump and adjust the speed, which greatly improves the convenience of operation. Submersible Sand Slurry Pumps can be easily deployed and relocated in different areas without the need for complex infrastructure or heavy machinery. This flexibility is particularly beneficial in constrained or challenging dredging environments.

3.Submersible Sand Slurry Pump Successful Cases

In May 2021, we received inquiries from the customer in Saudi Arabia who were looking for submersible sand pump solutions. They previously used a horizontal sand pump, but after long-term use, they found that the diesel engine frequently broke down and the cavitation problem of the pump casing and impeller became increasingly serious. Although they attempted to replace the pump casing impeller, the repair work caused delays. To this end, they contacted OCEAN Pump’s professional salesperson Lingda Kong (contact information: whatsapp: +86 18562293317).
After many in-depth communications via email and video conference, Lingda Kong found that the sand extracted by the customer was fine and soft, so she suggested that they use a Submersible Sand Slurry Pump. In order to further increase the concentration, we also provide the customer with supporting water jet systems and side cutter systems. After fully understanding the customer’s on-site working conditions, Lingda Kong suggested that the customer use the existing hull platform. In addition, we also provide our the customer with 6-wire motor Submersible Sand Slurry Pumps that can operate on 380V and 660V voltages.
This suggestion has been highly recognized by customer. In order to meet the needs of customer, we also provide design drawings for modified platform, which to a certain extent helps the customer reduce the cost of hull production. After in-depth communication with the customer, the customer finally decided to switch from a horizontal pump to a Submersible Sand Slurry Pump and confirmed the purchase of our 75kW submersible mortar pump. The following are the detailed parameters of this product:
* Model: DMZ 470-22-75
