The QXN series built-in electric submersible
engineering pump is manufactured as per GB/T 25409 2010 Small-size
submersible motor-pumps. This pump uses 10 m long cables. Developed
through direction connection of the dry-type or oil-immersed motor
and the pump, it is of a unique lower-suction, upper-discharge and
self-cooling structure in which water flows out of the part between
the outer cylinder and the motor base to cool the motor and achieve
a good self-cooling effect so that the disadvantages of other
electric submersible pumps that can\'t operate without water are
avoided and the lifetime of the electric pump is significantly
prolonged. This pump features small outer diameter, light weight,
lower suction structure, easy operation and good capability of
draining shallow water on the operation surfaces of ship bilges,
infrastructure construction sites, mines, etc. Besides, the pump
designed with a flange interface on the suction end can be used as
a pipeline pump in the fields such as pressurized water supply for
high-rise buildings and pressurized agricultural sprinkling
irrigation.
Product use:
It is applicable to drainage for operation
surfaces of water conservancy projects, urban construction
projects, industrial and mining enterprises, etc., ship bilge
drainage, agricultural drainage and irrigation, well water lifting,
pressurized water supply for high-rise buildings and infrastructure
construction site drainage.
