The suction house is located in front of the dredger, its shape has a significant impact on productivity.
Usually we use two types of suction heads: oval suction head and traverse suction head.
The suction dredger relies on the centrifugal mud pump installed on the dredger to produce a certain vacuum in the suction pipe, and the suction head at the top of the suction pipe will suck the mud, sand and other loose materials from the water bottom together with water and raise them to the water surface, and finally, through the discharge pipe of the mud pump, the sucked mud will be discharged into the barge or transported to the specified area.
