Audited Supplier The River Sand Dredger is a powerful tool that is widely used to recover materials from great depths and can even extract sand from underneath a clay overburden. Equipped with a high-pressure water pump and a powerful sand suction pump, the River Sand Dredger is designed to produce a high-pressure high-speed water jet to impact the sand layer and splash the mixed sand around the suction head. The sand suction pump then conveys the sand to the desired location through the discharge pipe.
At OCEAN Pump, our River Sand Dredger is designed with an integrated structure that includes a dredge body, a high-efficiency wear-resistant marine sand pump, a high-pressure water pump, a famous brand diesel engine, and a discharge system. Our River Sand Dredger is highly efficient, wear-resistant, flexible, and energy-saving in the delivery of solid particles, making it the most economical option for loose fine sand in water bottoms. We offer various small and medium-sized jet suction dredgers that can be customized to meet your specific demands.

We recently received an inquiry from Mr. Peter, a professional contractor for construction projects in Liberia. He needed to pump sand from a river in Liberia and use it for construction after treatment. After confirming the detailed working conditions, our engineers recommended the 10-inch River Sand Dredger equipped with our heavy-duty sand pump, which is suitable for the customer's specific requirements.
The River Sand Dredger is designed with a main hull that measures 6m x 2.2m x 1.8m, and site pontoons measuring 8m x 1.1m x 1.5m. The sand pump has a size of 10 inches, with an input diameter of 250mm and an output diameter of 200mm, allowing for a sand capacity of 200-300m3/h. It has a dredging depth of 20m and a discharge distance of 400m, making it ideal for Mr. Peter's needs.
To power the sand pump and water pump, the River Sand Dredger comes with a diesel engine with a power of 280 hp and a speed of 1800rpm. It also includes a water pump for jetting sand with a 4-inch size, a water capacity of 100m, and a head of 50m. Additionally, a generator with a power of 50kw is included to provide power for all the electric machines.
At OCEAN Pump, we take pride in providing tailored solutions to meet our customers' specific needs. Our engineers carefully consider all the details to ensure that the equipment we provide is the most suitable for the job at hand.
In order to facilitate the operation and maintenance of customers, we have considered the following aspects in the design of the River Sand Dredger:
Following our recommendations and detailed discussions with Mr. Peter, we received the order for the 10-inch River Sand Dredger, propeller, 400m discharge PE pipes, and 30 pairs of floaters for some pipes. We sent the PI with bank payment information and received a 40% advance payment from the customer on April 20th. We then arranged production in our workshop, with an agreed production time of 25 working days till May 23rd.
We ensured that the River Sand Dredger was completed as scheduled and conducted thorough running testing to ensure that all engines were working smoothly and the pump was functioning well. After providing Mr. Peter with a testing video, he was satisfied with the results and paid the 60% balance on May 21st. We promptly arranged the earliest containers and vessel for him and loaded the River Sand Dredger on May 25th.
We assisted Mr. Peter in confirming the detailed information on the bill of loading and provided the necessary documents for customs clearance. After the vessel left the port, we provided him with a schedule for reference. Our team at OCEAN Pump takes pride in providing professional support and excellent service, and we are pleased to hear that Mr. Peter was satisfied with our cooperation.
