Dewatering irrigation submersible borehole pump
Application
QJ series deep well submersible pump consists of the electrical machinery and the pump body. It is widely used it hydraulic engineering facility, for example sea water transfering, irrigation on farmland , draining water in industry and mining enterprise: architectural engineering precipitation ,also in cooling system of river, reservoir, eruptive fountain, hot spring bathing place: and so on. .It's main characteristic is that the combination of pump and electrical machinery, working in the deep water, easy to use, repairs, with great efficiency, also safe and reliable.
Operate Condition
1. power source:380v,3ph,50hz
2. water qualities
not above 25ºC(85ºC for the type of heat-resisting)
