Audited Supplier Cutter suction dredger makes use of a cutter head to loosen the underwater material to be dredged and pumps the dredged material via a pipeline ashore or into barges. The powerful cutter swings of the cutter suction dredger around the spud-pole powered by winches while dredging, then the high pressure sand pump suck up the loosened mixed materials to the destination through the suction pipe. The cutter suction dredger is suitable for heavy duty and durable dredging operations with dismountable structure.
The cutter suction dredger is often designed easily to transport by road, rail or by ship due to its reasonable size and weight of the various dismountable modules. The complete cutter suction dredger consists of one main pontoon and two side pontoons which are mounted to the main pontoon using heavy duty steel eyes and pins at the bottom of the hull, they are connected at deck level. The pontoons are of welded steel constructions with heavy frames, beams and longitudinal girders. Extra reinforcements are placed where necessary to withstand all forces while dredging. cutter suction dredger is widely used for river silt cleaning, delisting lakes and ponds, mining project, cleaning ports and sand production.

OCEAN Pump had been dedicated in designing and manufacturing sand pump, slurry pump, gravel pump and sand dredging equipment for over 30 years. Our sand pump and sand dredge products had been exported to over 60 countries. OCEAN Pump brand cutter suction dredger can be used for the following applications.
The customer bought famous brand sand pump from Australia and diesel engine themselves. They tried to find suppliers that can provide the cutter suction dredger body and whole hydraulic system, in which the steel plate should be complied with ABS standard. It is our honor to receive their inquiry. After communicated with them, they sent us dredger drawings. We found that the customer need a cutter suction dredger .They wanted to add a flushing equipment to wash the cutter suction head. We showed this request to our engineer. After a professional discussion, we can customize it according to the requirements of the customer. After a preliminary negotiation, the customer sent a business representative to visit our company.
We talked about the cutter suction dredger design in detail, as our customer bought the pump and diesel engine themselves. We only need to provide the sand dredge body and hydraulic system. However, many technical problems need to check and match, so after several days of discussion, we finally confirmed the technical details. Meanwhile, the customer also concerned about the after-sale and installation problems. We promised that we can send our engineers to work site to install and debug the cutter suction dredger system. We will help them to train their workers to operate the cutter suction dredger skillfully.
The representative were satisfied with the our scheme and services .He signed a contract with us and delivered a deposit at once. We purchased materials , arranged production and start to produce according to the contract requirements. As the workshop production plan is already full, our customer wanted to pick up the Sea sand dredger as soon as possible. On the premise of guaranteeing the quality, we finished the cutter suction dredger in advance.
