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.
