Sub dewatering pump is also called submersible dewatering pump which puts the electrical motor and mechanical pump on the same axis to make it running reliably and efficiently. The bottom of the submersible sediment pump body is equipped with a stirring impeller, which can stir the deposited sludge to form a turbulent flow and achieve high concentration transportation. The sub dewatering pump can be directly submerged into water, eliminating the step of pouring water, so the operation is relatively simple. OCEAN Pump brand ZJQ series sub dewatering pump can be used for extracting liquids contains solid particles such as sand, stone and cinder, also can be used for removing and transporting of mud and water mixture in metallurgical, mining and thermal power plants.

One customer from Hunan signed a local sludge treatment project. There are 14 sludge pools which are 8m deep, 5m long and 5m wide. The sludge contains a small amount of sand. The required discharge distance is 150m and sediment capacity is 20m3/h. When contacted OCEAN Pump engineers, the customer requested the sand pump machine should has the features of good wear resistance and convenient operation. Our engineers recommended the sub dewatering pump.

After studying the submersible slurry pump and watching the on-site using video, the customer finally approved the plan provided by OCEAN Pump and signed purchase contract for 2 sets submersible slurry pumps.

The submersible dewatering pumps were delivered to the customer’s designated working site on August 14th, 2019. The next day, the workers started to carry out running test. One of the sludge pools’ mud concentration is about 60% which is a little higher, so the customer used high pressure water to impact the mud to improve sludge fluidity. After one hours’ running, the extracted sludge concentration was 40%, and there was no blockage. The sub dewatering pump fully meets the customer’s requirements. Therefore, the customer ordered another 4 sets sub dewatering pumps to improve the working efficiency.
