Jet suction dredger is widely used to recover materials from great depths and can also extract sand from below a clay overburden which is also called jet sand suction dredger. Jet suction dredger is equipped with high pressure water pump and powerful sand suction pump. The water pump can produce high pressure high speed water jet to impact the bottom of sand layer and splashing the mixed sand around the suction head, and the sand suction pump conveys the sand to the destination through the discharge pipe.
Jet Suction Dredger Features
Novel design, High efficient, large output, long discharge distance
High quality wear resistance and long serve life sand pump
Pumping depth reaches up to 20-30 meters underwater
Dredge hull consists of multiple pontoons connected by proven coupling system
Highly efficient fuel consumption and minimum overall operational costs
Control box and instrument are mounted in ergonomic dash board
Low investment and good operating performance
Simple and fast assembly and disassembly, easy to operate
OEM, ODM, customization are available
