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. As the leading sand dredger designer, manufacturer and exporter, TAIAN OCEAN Pump Co., Ltd (OCEAN Pump) had been dedicated in supplying sand dredging machines to worldwide customers for over 20 years.
