centrifugal sand pump
At present, centrifugal sand pump is widely used in various conditions such as dredging and embankment in the Yellow River Basin, Yangtze River Basin, coastal reclamation, and inland river sand mining.


One customer inquired our company’s sand suction pump with model 200PNS-30 in 2017 for the sand pumping operation in Cambodia. It was the first time that the customer carried out sand pumping project. After talking about the working conditions with the customer, we knew that they haven’t exploration in the local river, the preliminary operation was experimental.
Our engineers recommended the customer small-scale sand pumping equipment which had three advantages.
  1. It was convenient for local installation.
  2. The quality was stable and reliable.
  3. The investment was small, and the use risk was minimized.
According to the customer’s actual requirements, our engineers recommended centrifugal sand pump set with model 200PNS-30. The customer made the pontoon by themselves, he could save costs by this way. By watching videos, inspecting and comparing other companies’ selection plans, the customer finally selected our company’s recommendation plan and signed a purchase contract.
After using the centrifugal sand pump more than half a year, the customer responded two issues.
  1. There were many garbage in the river which often blocked the impeller of the centrifugal sand pump.
  2. The sand layers in some river sections were hard, this leaded to low working efficiency of sand pumping machine.
The customer wanted us to supply solutions. Our engineers gave two suggestions.
  1. Replace the current impeller withopen impeller to improve the performance and reduce the blockage.
  2. Upgrade the dredger hull ,add cutter suction system to stir up the hard sand layer, increase the sediment concentration in the water, and improve the efficiency of sand pumping.
The customer accepted the modification proposal and organized the production of the cutter suction device. After modification, the efficiency of sand pumping increased a lot, and the probability of blockage was reduced, the probability of downtime caused by garbage blockage was also reduced. The customer was very satisfied with this. At the same time, the customer had a better understanding of the local sand source, he decided to expand the production scale and purchase another centrifugal sand pump. After the communication with us, he selected the centrifugal sand pump 300PNS-35.

River Sand Dredger Design Improvement

River sand dredger is easy to operate and with high efficiency. This 10 inch sand dredger is widely used in sand dredging, slurry dredging, port buildings, desilting and other dredging fields.
This dredger is also called portable jet suction dredger . The sand dredger with the high-pressure water pump can produce a certain degree of vacuum, so that the underwater sand and mud are mixed into slurry. The mixed slurry is transported to the designated position through the discharge pipeline.
This type of river sand dredger can be self-propelled or non self-propelled. It depends on customers’ requirement. The portable type can be transported through roads, railways, containers, etc. It is very convenient to install and move in the workplace. Further benefits include reduced wear and tear on pumping equipment, a low carbon footprint and minimal noise pollution.


Now we do some details improvements for this very popular simple sand pump dredger. Make it looks more perfect.
1. Add protective cover to the engine belt. When engine is running, the belt works at high speed. The cover could protect the safety of the staff.

2.Add a walking channel to the middle of the river sand dredger so the staff can go to the dredger opposite directly, needn’t passing round the dredger tail again.

3.Adjust the horizontal distance from the gantry top to the dredger front edge . To prevent the sand suction hose from hitting the edge of the sand dredger.

4. Add air release valve in the outlet elbow of the sand pump. When the pump is working, it will suck some air into the pump. It will corrode the pump casing, after we increase the air release valve, it can release the air inside, and extend the service life of the pump.


5.The oil drain valve of the fuel tank is installed at the bottom of the oil tank. After the diesel engine has been working for a period of time, some water is mixed into the return pipe. The diesel oil with water will damage the diesel engine. A bottom oil drain valve installs at the bottom to release the oil and water. Guarantee the purity of diesel.

This river sand dredger is the powerful equipment to excavate and pump underwater sand, slurry or gravel to specified location.
