1.What is Submersible Dredge Pump with Agitators

The DMD type submersible dredge pump is a heavy-duty slurry pump equipped with 2-3 side agitators. The motor and the submersible dredge pump work coaxially and immersed in the medium. The flow channel components of the submersible dredger pump are made of high alloy wear-resistant materials, so the submersible dredge pump has good wear resistance and long service life. submersible dredge pumps are suitable for transporting sludge, slurry, coal slurry, sandstone and other media containing large solid particles. The unique mechanical sealing device can effectively balance the pressure inside and outside the oil chamber, thereby achieving the most reliable sealing capability. The OCEAN Pump submersible dredge pump motor adopts various protections such as overheating protection and water inlet detection protrusion, which can operate safely for a long time under harsh working conditions.
The dredging pump with agitator is designed and manufactured using advanced technology at home and abroad. In addition to the main impeller, the submersible dredge pump also has a bottom agitator at the bottom, which can stir the water flow and form turbulent flow. Therefore, the submersible dredge pump can achieve high-concentration transportation without auxiliary devices. And for particularly hard or viscous solid layers, the OCEAN Pump submersible dredge pump is equipped with two or three additional agitators to improve work efficiency.
The price of a submersible dredge pump with agitator can vary greatly depending on various factors such as brand, model, specifications, and additional features. In addition, market conditions and regional differences can also affect prices. To determine the exact cost, it is best to contact the manufacturer, distributor or supplier of the dredge pump. OCEAN Pump can provide you with specific pricing information based on your requirements and current market conditions.

2.How to choose Submersible Dredge Pump with Agitators

1.Submersible Dredge Pump with Agitators Flow and Velocity:

The flow rate of a submersible dredge pump is a very important parameter. It represents the volume of material that the submersible dredge pump can handle per unit time. This material volume can include a variety of substances, such as common sand, water, etc. There are usually two units of pump flow, one is cubic meters per hour (m³/h), and the other is gallons per minute (GPM). Although these two units are different, they are both used to measure the working efficiency and processing capacity of the submersible dredge pump.
Here, we need to explain in particular that the so-called flow refers to the mixed flow of sand and water. This mixed flow rate is considered based on the customer’s dredging needs, because it directly affects the working effect of the submersible dredge pump. If the material capacity you need to handle is large, you need to choose a pump with a larger flow rate. Otherwise, you can choose a submersible dredge pump with a smaller flow rate.
In addition, when selecting a pump, another factor needs to be considered, which is the working flow rate of the submersible dredge pump. The faster the working flow rate of the submersible dredge pump, the stronger its ability to handle materials. However, this also means that the submersible dredge pump will wear out faster and its service life may be affected. Therefore, when choosing a submersible dredge pump, we need to find a balance point between flow and flow rate, not only to ensure the processing capacity of the submersible dredge pump, but also to take into account the service life of the pump.
The flow rate of a submersible dredge pump is a very important parameter, which directly affects the working effect and service life of the pump. When choosing a submersible dredge pump, OCEAN Pump will select the appropriate flow rate and flow rate based on the actual needs of the customer to achieve the best working results.

2. Submersible Dredge Pump with Agitators Lift Head

The lift head is the maximum height or distance that the submersible dredge pump can lift or transport dredged materials vertically or horizontally. It is usually measured in meters or feet. Evaluate the required submersible dredge pump lift head based on the distance the material needs to be transported.
The head of a submersible dredge pump plays a vital role in the pumping system. It refers to the maximum height or distance that the submersible dredge pump can lift or transport dredged materials vertically or horizontally. This parameter is usually measured in meters or feet to facilitate selection of the appropriate pump equipment based on the actual application scenario. The liftv head of the submersible dredge pump not only affects the material transportation effect, but also is related to the operating efficiency and stability of the entire pumping system.
When evaluating the pump lift head, OCEAN Pump fully considers factors such as material characteristics, conveying distance, topography, and other factors. Select the appropriate submersible dredge pump lift head for the customer based on the distance the material needs to be transported. If the submersible dredge pump lift head is too high, it may reduce the operating efficiency of the pump and increase energy consumption and maintenance costs; conversely, if the submersible dredge pump lift head is too low, it may affect the material delivery effect and even cause instability in the pumping system.

3. Rated Power and Voltage Frequency of Submersible Dredge Pump with Agitators

The rated power of a submersible dredge pump dredge pump is a key indicator of pump motor performance, which is expressed in kilowatts (kW) or kilovolt-amperes (KVA). When selecting a submersible dredge pump, the first thing to consider is the rated power of the pump to ensure that it can meet the needs of the actual application scenario. In addition, the power requirements of the pump should also take into account the characteristics of the dredging conditions and pumped materials to ensure that the pump can perform well under various working conditions.
Another important factor when determining the power requirements of a submersible dredge pump is the voltage frequency of the customer’s country. There are differences in voltage frequencies in different countries. Therefore, when purchasing a submersible dredge pump, make sure that the voltage frequency of the submersible dredge pump dredge pump matches the power grid standard of the country where the customer is located. Commonly used voltage frequencies are 380V/440V/660V, and the frequencies are 50HZ and 60HZ respectively. If the voltage frequency does not match, it may affect the normal operation of the pump or even damage the equipment.

4.Submersible Dredge Pump with Agitators Design

When searching for a submersible dredge pump with an efficient agitator, it is important to focus on a number of key elements to ensure that the synergy of the agitator and submersible dredge pump meets your needs. These factors include the number, size and type of agitator blades and their performance in mixing and suspending sediment or sludge.
First, you need to know the number of agitator blades. Usually, the greater the number of blades, the better the mixing effect. This is because more blades create greater shear, effectively stirring and suspending sediment or sludge. However, the structure and performance of the submersible dredge pump also need to be considered, as too many blades may cause an increase in pump power, which in turn affects the submersible dredge pump’s operating efficiency. Therefore, when selecting a agitator, a balance point should be sought to ensure the mixing effect while avoiding excessive burden on the pump.
Secondly, the size of the agitator blades is a crucial consideration. The right size can improve mixing results, while the wrong size can result in under- or over-mixing. Larger blades have stronger stirring power and are suitable for larger particles of sediment or sludge; while smaller blades are suitable for smaller particles of sediment or sludge. Therefore, when selecting a agitator, the appropriate blade size should be selected according to the actual application scenario.
In addition, the type of agitator is also an important aspect to pay attention to. Different types of agitators produce different flow fields and shear forces during the mixing process, so their mixing effects are also different. OCEAN Pump even designed a cutter type agitator to adapt to different working conditions.
When looking for a submersible dredge pump with an efficient agitator, it is necessary to fully consider the number, specification and type of agitator blades to ensure that its synergy with the submersible dredge pump can meet the needs.

3.Successful Cases

In 2023, a customer recently accepted a challenging project to fill geotechnical pipes by pumping sand from the sea. The key requirement of the project is that the sand pumping output needs to be maintained at 70-100m3/h, and at the same time, the sand material must be transported to a discharge point 200-300m away under the condition of a height difference of 6-8m.
In order to meet these requirements, the customer initially planned to use a submersible dredge pump to excavate sand, and then transport the excavated sand to the geotechnical pipe through a booster pump. However, after in-depth calculation and analysis of project parameters by the OCEAN Pump technical department, it was found that this solution was not the best choice. OCEAN Pump salesperson Lingda Kong (Whatsapp: +86 185 6229 3317) proposed that only two DMD200-25-30 submersible dredge pumps can meet all customer needs without the need for additional booster pumps. This move not only ensures work efficiency, but also saves costs for customers.
The DMD200-25-30 submersible dredging pump has won the favor of the technical department due to its excellent performance and high efficiency and energy saving features. The pump is designed with full consideration of complex working conditions and can operate stably in extreme environments. The powerful sand pumping capacity enables it to transport a large amount of sand in a short time. In addition, OCEAN Pump is equipped with two 5.5kw agitators for the pump to fully mix the sand materials during the sand pumping process, improve the fluidity of the mortar and reduce the risk of pipeline blockage.
After understanding this solution, the customer spoke highly of our company’s professional capabilities and technical level and expressed satisfaction. Finally, they decided to order two DMD200-25-30 submersible dredge pumps with 5.5kw agitators to meet the project needs.

Detailed parameters are as follows
Model-DMD200-25-30
