In order to meet the needs of urban flood control and sewage (stains), saving pumping station project cost, Changsha Electrical Machinery Factory Co., Ltd. and Jiangsu University, Wuxi Pump Works jointly developed the first batch of 10 600QW3000-40-500kW 10kV large high-voltage dry run Submersible sewage pump, a few days ago in China's largest installed capacity of Anshan Iron and Steel large sewage pumping station put into use. Not long ago the pump station in the typhoon storm attack, played the power of rapid sewage to ensure normal and orderly production and life of Ansteel. The new product high lift, up to 40 meters. Its core motor for the first time in our country with high voltage, built-dry-pressure structure, reliable performance and high efficiency. The product motor and pump form one, without the need for on-site labor-intensive, but also can greatly simplify the civil engineering and construction of the pumping station structure, reducing the footprint and saving pumping station project cost up to 30%. Its successful development not only filled the domestic blank, but also marked the development of China's large-scale submersible pump and reached a new level.
