Small Particle Sand Dredge Pump Submersible For River Sand Cleaning

Submersible Dredge

Submersible dredge, also called submersible slurry pump dredger, is designed and manufactured with optimized hydrodynamics technology for sand dredging and silt clearing. SLAPK brand ZJQ series submersible dredge is equipped with our own specially designed submersible dredger pump, advanced high efficiency suction reamer head and the famous brand motor. All of them are integrated together to realize high dredger suction ratio, more thorough dredging and large slurry or sand output.

SLAPK brand heavy duty submersible pump is made of high-chromium alloy material with good wear-resisting property and big flow passage way which is suitable for transportation of even 60mm diameter medium including mud with big solid particles, ore pulp, coal pulp and coarse sand, etc. The flexible sensing probe can realize over-heating protection, water-intake inspect protection and oil chamber protection, ensuring long and safe pump operation under abominable working conditions. Our submersible dredge features reliable, efficient and robust design, strong dredge body construction, cost saving, easy to operate and maintain. It is the best dredging equipment for small and medium scale multifunctional dredging projects.

River Cleaning Application

In China, two methods are generally used for river dredging: cutter suction dredger and excavator combined with dredger. However, the investment in these two methods is relatively high. Therefore, it is an ideal choice to use submersible dredging pumps (submersible dredge pumps) for small-scale dredging and dredging projects.

Directly use the submersible sand pump to dredge.

In this way, a sand pump type with a wider impeller flow path should be selected. Because the dredging site generally has garbage and other debris, which is prone to blockage, special impellers should be used. And making filter screen at the bottom of the pump, and the size of the mesh should be determined according to the flow diameter of the pump. In environments with a lot of debris, you should also consider a longer and larger diameter filter, or a double-layer filter.

To prepare more than two special reamers. The reamer is different from the configuration for sand pumping. It must be made into a plough-shaped knife tooth, which can rotate the mud layer, and then cooperate with the high-flow high-pressure water pump to disperse the mud layer, and rush to the suction port of the submersible dredging pump to ensure the content The mud concentration can achieve the effect of dredging and dredging.

The bottom of the submersible dredge pumps is generally equipped with a stirring impeller. In this dredging working environment, the stirring impeller is generally removed. Because the stirring impeller does not play a good role at this time, it is easy to entangle the debris.

The submersible dredge pumps cooperate with the excavator for dredging

There are two shortcomings of dredging with an excavator alone. The first is that the dredging efficiency is low and it can only handle close-range sludge. The second is that it cannot work in deep water areas and needs to be installed on a ship. These two problems can be solved by using the submersible sand pump to cooperate with the excavator. The hydraulic system of the excavator is used to drive the submersible dredge pumps. The hydraulic energy is converted into mechanical energy. When working, the energy is transferred to the slurry medium through the rotation of the pump impeller, so that it generates a certain flow rate, drives the solid matter to flow, and realizes the delivery.

How to select a submersible sand pump for river dredging

1. Real factory. Real factory is the important factor you should consider when you select submersible sand pumps. Generally speaking, real factory have its own product design, production, quality assurance and installation team, manufacturing machines and testing equipment, certifications, etc al.

2. Complete product series. Complete submersible sand pumps will easily satisfy your requirements. ZIODNG Pump have submersible sand pumps and submersible slurry pumps with different configuration for you demands and can be used in corresponding projects.

3. Product quality. Product quality is most important for your selection in the long life span. ZIDONG PUmp has strict quality management system to ensure its sand pump product to keep finest and uniform quality. We have standard industrial testing equipment to inspect our submersible sand pumps product quality in preset procedure. All our sand pump and sand dredger products had been certificated by the ISO9001, CE, SGS, etc.

4. Factory price. The submersible sand pump from the real factory can give you competitive factory price in controlled product quality and promised delivery time.

5.Certifications. ISO9001, SGS are the required certificates for all submersible sand pumps. Firstly of all, the submersible sand pumps you purchased should follow your country’s laws and regulations.

6. Successful cases. Successful submersible sand pump cases witnessed the passed efforts and abilities of the sand pump suppliers, you should try to visit them to verify you judgement. We had been specialized in designing, manufacturing and supplying sand pump, slurry pump, gravel pump and dredger equipment for more than 20 years. We had provided many types of effective and states of the art sand pump products to over 36 countries. We are not only manufacturing best quality sand pump products but also providing professional design and installation service. OEM and ODM are also available.

7. Installation and after sale service is also important when you need help.
