This submersible pumps, made from heavy gauge cast iron offering exceptional sturdiness, abrasion resistance and

durability, are suitable for pumping clear or slightly dirty water.They distinguish themselves for their sturdiness and

reliability under automatic operating conditions in fixed installations. As portable electric drainage and irrigation

devices, QDX series submersible pumps with lower water input are widely suitable for water cluster boxes, farmland,

industrial and mining enterprises, construction sites, ship and family, and characterized by less volume, light weight

and convenient operation etc. If the pump with a float switch, it is possible to achieve the automatic control. Single

phase capacitor running asynchronous or 3ph asynchronous motor is equipped in this pump and installed with a

built- in thermal protector, and can be automatically cut- off in the case of overheat or over current, thus assuring

safe and reliable running under worse circumstances.
