BQS2.2kw-315kw full head mining explosion-proof sewage desilting agitator pump is jointly designed and developed by our company and Jiangsu University, according to MT/T671-2005 standard, which is suitable for coal mines which may have a lot of coal slime. Based on the original mining explosion-proof sewage desilting submersible pump, the product's innovative design equips a stirrer at the bottom of pump. Which effectively discharge the sewage such as coal slurry and slime. This series product utilizes two patents from Jiangsu University, the impeller and volute casing are designed into double flow channels, outlet width between two impeller blades is more than 30mm, which ensures strong overflow capacity. The impeller blade curve utilizes patent technology to ensure that input power will not exceed the motor power (no overload) under any condition. One pump can serve muti-purpose to provide users with great convenience, and can save over 10% of electrical energy. In order to make the pump operate with or without water, we have designed the product with a strong cooling interlayer structure. So this submersible electric pump series can completely meet the needs of underground coal mines. Compared with the similar products in China, it has the features of advanced technology, superior performance, energy saving and longer life.
