Summary.
Dragon Tatsu QJ type submersible pump is from the deep well groundwater extraction in complete sets of equipment, widely used in agricultural irrigation, industrial and mining enterprises for drainage and highland, mountain with water. QJR type well water pump, using special materials and structure, used for the extraction of underground hot water. In addition the company produced according to user needs water, mining and other special occasions with submersible pump. The pump is host by QJ type submersible pump and YQS type submersible pump machine. Underwater work, has the advantages of compact structure, small volume, light weight, installation, using, convenient maintenance, safe and reliable transportation, energy saving etc..
