Heavy duty submersible pump is designed and engineered for complex heavy-duty pumping applications to handle high mixture densities such as sand, slurry, sludge, wastewater and gravels, etc.

1. What Is Heavy Duty Submersible Pump?

A heavy duty submersible pump is a specialized pump designed for demanding pumping tasks where the pump operates while submerged in the fluid being pumped, such as sand, slurry, sludge, wastewater, and gravels. These pumps are commonly used in industries like mining, construction, dredging, and wastewater treatment.

Constructed with robust materials and components, heavy-duty submersible pumps are designed to withstand harsh conditions and handle high mixture densities. They feature high-powered motors and efficient impellers to move heavy mixtures effectively. The pumps often have combat structures, ensuring durability, high efficiency, and flexible operation.

Our range of heavy-duty submersible pumps is specifically designed to handle wastewater with high levels of contaminants, including solids and rags. They find applications in various industrial and municipal settings.

Our heavy-duty professional-grade sump pumps are equipped with high-efficiency motors featuring upper and lower ball bearings, providing cooler operation and extended lifespan. The vortex impeller design helps prevent clogging. These sump pumps come with a piggy-back switch and can be manually operated by overriding the switch.

At OCEAN Pumps, we understand the demands of mining, sand and gravel operations, power generation, and heavy industries. That’s why we offer a range of submersible slurry pumps manufactured to meet the rigorous requirements of abrasive service applications.

2. What Is Heavy Duty Submersible Dredge Pump

A heavy duty submersible dredge pump is a specialized type of pump designed for dredging operations. It is designed to be submerged in water or other liquids while effectively removing sediment, debris, or other materials from the bottom of rivers, lakes, harbors, and other water bodies. The submersible slurry pump can be directly powered by either a hydraulic or an electric motor assembled within a protective case which features combat structure,

Submersible dredge pumps are widely used in various applications such as mining, construction, environmental cleanup, and waterway maintenance. They are equipped with a motor and impeller, and they can be lowered into the water to pump out sediments and transfer them to another location.

The submersible design of these pumps allows them to operate efficiently underwater without the need for external priming. They are available in different sizes and configurations to suit specific dredging requirements.

In summary, a heavy-duty submersible dredge pump is an essential tool for dredging operations, providing efficient and reliable removal of sediments and debris from water bodies.

OCEAN Pump is the professional slurry pump manufacturer and supplier,  we offers NSQ series high quality submersible dredge pump for mine slag and mud extraction. The NSQ submersible sand pumps produced by OCEAN Pump are equipped with temperature sensors, water inlet detectors, mechanical seals, wear-resistant flow parts and optional stirrers to ensure that the equipment can still work normally even under the harshest conditions. The design of the NSQ heavy duty submersible pump series is also easy to maintain. The pump can be easily disassembled to inspect key components such as heavy-duty impellers and pump casings. This means higher flow, less downtime and lower overall operating costs.

3. Why Chose Heavy Duty Submersible Pump Africa for Slurry Dredging

Choosing a heavy-duty submersible pump from Africa for dredging slurry offers several advantages. Firstly, the China Railway Construction Corporation Limited (CRCC) is a reputable and experienced construction enterprise with 32 branches, including long-term collaborations with companies like the 14th Bureau Group Co., Ltd. and the 20th Bureau Group Co., Ltd. This demonstrates their expertise and ability to contribute to railway, highway, and construction projects.

In the bid-winning project located in a landlocked country in Africa, a heavy-duty submersible pump is required to pump sedimented silt in the construction of a water plant. The chosen pump, the DMD250-35-55 submersible dredge pump with a submersible agitator, is ideal for handling the sludge-like sediment that cannot be completely washed up by a water gun alone. This selection ensures efficient and effective dredging.

As a perennial partner, OCEAN Pumps actively organizes the supply of supporting supplies and ensures timely delivery within the contract period, prioritizing customer satisfaction. This partnership and commitment to fulfilling contractual obligations further strengthen the reliability and trustworthiness of choosing a heavy-duty submersible pump from Africa for dredging slurry.

Overall, the combination of the reputable construction enterprise, specific pump selection, and reliable supply chain makes the choice of a heavy-duty submersible pump from Africa a favorable option for successful dredging operations in challenging slurry conditions.

4. DMD Heavy Duty Submersible Pump Africa Prameters for China Railway Construction:

  • OCEANbrand DMD submersible dredgepump model: DMD250-35-55
  • Flow rate: 250 cubic meters/hour.
  • Head: 350 meters
  • Purpose: 980 rpm
  • Matching power: 55kw
  • Power of the force agitator: 5.5kwper piece
  • DMD submersible dredgepumping pipe specification: 150mm
  • DMD submersible dredgepump soft start control boxspecification: 75kw

On May 24, 2018, the DMD heavy duty submersible pump was assembled with a two-pole submersible mixer, and the supporting soft-start control box was also assembled, and our company organized personnel to debug the equipment. In the test pump room, the main parts of the DMD submersible dredge pump were tested for the pump casing sealing and impeller balance; the electrical clearance and creepage distance tests; the motor performance test; the overall performance test; All tests are qualified and allowed to leave the factory.

The soft start control box is mainly used to start various types of high-power motors. The DMD heavy duty submersible pump for OCEAN Pumps uses soft start to replace the traditional direct start method to achieve a smooth start, reduce the starting current, and reduce the mechanical impact of the large current on the motor on the motor starting and the impact on the power grid. The purpose of using the soft start control box is to improve power quality and save energy. The control box adopts stall protection and fast protection functions to avoid mechanical failure or stall stalls, which may cause the motor to burn out due to overheating, reduce the voltage drop caused by high current, reduce wear, extend the service life of the motor, and save mechanical maintenance costs.

Advantages of soft start control box:

  • Reduce starting current and reduce current impact;
  • Energy saving and improve use efficiency;
  • Stall protection reduces equipment failure rate and prolongs service life.
  • Wide application range.

DMD heavy duty submersible pump and submersible agitator each have a set of signal lines, which are protected by the submersible motor in the control box. Among them, DMD submersible dredge pump has WC (thermal protection core wire), XL (water inlet protection core wire), YS (oil-water probe core wire); submersible agitator has WC (heat protection core wire), XL (water inlet protection core) line). In the soft start control box, each cable needs to be reflected in the circuit separately. The electrical designer of OCEAN Pump connected with the control box manufacturer, and designed a unique soft-start belt protective control box, which solved the connection problem of the control cable. In the idling test, the soft starter runs smoothly, and all the data meet the design and construction requirements, and reach the factory requirements.

Due to the relatively harsh local construction conditions of customers, it is difficult for customers to obtain standard parts and accessories. Therefore, when supporting the DMD heavy duty submersible pump, our selection engineer designed two high-pressure water guns on the pump body to prevent hinges. In the case of a knife failure, the pump unit can continue to operate stably. The plan designer also selected soft starters, stirrer angle teeth, pump mechanical seals, stirring impellers and other accessories in the design plan to ensure that it is safe to use.
