The wetted parts of the pump are made of high chromium wearable alloy , so the pump has good wear resistance and large flowing passage.
It is applicable for conveying medium such as sludge, ore slurry, coal slurry, sand stones containing big solid particles.
Zidong hydraulic submersible dredge pumps are suitable for 120, 150, 220, 240, 300, 330, 360 and other small, medium and large series of excavators. Besides, they are specialized for those circumstances that are difficulty to dig, such as much more water and watery sludge and sand. Remove the bucket and connect to the hydraulic mortar pump, concentration of extraction with high efficient and density could be achieved. The work efficiency improves greatly with the matching hydraulic slurry pump and long-distance transportation is also realized. In addition, it could be equipped with hydraulic station and applies to the harsh environment. Hence, several difficulty conditions could be dealt with such as excavators digging ineffectively, long-distance transportation of mud and mortar, lack of electricity supply and frequent switching conditions. In conclude, it can supply to various conditions.

• The bottom of the pump has a mixing device, and it also could be equipped with bilateral or multilateral agitator additionally in order to prevent large pieces of fixed material clogging the pump and fully making the solid and liquid mixed, thus it is more convenient to handle.
• This slurry pump can handle the solid material with maximum particle up to 50mm, extraction concentration of solid-liquid could be up to 70% or more.
• The device is mainly installed in the excavator, and powered by the excavator hydraulic station so that a free transition could be provided. Be sides, with the power source of the diesel engine, the problem of inconvenience of electricity during construction in remote areas can be solved.
• Wetted parts: the pump casing, impeller, guard, mixing impeller are all made of high chrome alloy. Other materials can be customized.
• With the unique seal device, it could avoid frequent changing machine seal and improves work efficiency.
Note: Due to different working conditions, the pump output may also change with the medium, operation, transportation distance and other factors.
