INSTALLATIONS AND USES
QDX series submersible pumps with lower water input are widely suitable for farmland, industrial and mining enterprises, construction sites, ship and family, and characterized by less volume, light weight and convenient operation etc. if the pump is fitted with a floating switch, it is possible to achieve the automatic control of start-stop action under no ones care. Single phase capacitor running asynchronous or 3-phase asynchronous motor is equipped in this pump and installed with a built- in thermal protector, and can be automatically cut-off in the cases of overheat or over current,thus assuring safe and reliable running under worse circumstances.
