Submersible dredge pump is the powerful suction flood-proof centrifugal pump which is submerged and operated in the harshest conditions to handle highly corrosive and abrasive slurries. Slurry pumping is one of the most challenging applications. OCEAN Pump brand robust submersible dredge pump is made of the high quality wear resistant components to withstand abrasion and shock, it is engineered with all high chrome wet ends, pressurized sealing technology and run dry capability for the most demanding applications. The optimized high chrome steel impeller can ensure the best performance and operations in the best efficiency range. ZJQ series submersible dredge pump has the characteristics of high efficiency, high performance, excellent reliability, lower operating and maintenance cost and longer service life, it can handle concentration of solids up to 60 percent. ZJQ series submersible dredge pumps are suitable for complex heavy-duty applications to extract and handle slurry, sludge and sediments, etc.

In March 2021, a Malaysian customer consulted the product manager of Ocean Pump. He wanted to pump sand in the river. The water depth was 15 meters and the sand layer was 3 meters. All of them were fine sand. There was electricity at the site of 380V, and the required amount of sand was per hour. 100 cubic meters per hour, drain the sand through the PE pipe to a position of 200 meters and then wash the sand. Please help us to design a complete cost-effective solution.

Through meetings and discussions in the technical department, we provided customers with a ZJQ500-20-55 submersible dredge pump, with a flow rate of 500m3/h, a head of 20 meters, and a power of 55kW, which fully meets the needs of customers, with a 200-meter 8-inch sand pipe. Driven by a 380V power supply, equipped with two reamers and a 75kW variable frequency starter to start and protect the submersible dredge pump.

After 5 days of production and factory commissioning, the submersible dredge pump was shipped to Port Klang in Malaysia through our own freight forwarder in early April. After receiving it, the customer, after coordination in all aspects, finally started production in May, which is fully in line with his requirements. It is expected that it will be purchased again soon.
