QJ submersible pump motor and pump is direct one water pump into the water to work, it is suitable for deep groundwater, but also can be used for scooping from rivers, reservoirs and canals for water projects: mainly used for irrigation and plateau in the drinking water, but also for the city, factories, mines, railways, the site used for drainage.
QJ well submersible pump features:
1, motor, water pump, submerged operation, safe and reliable.
2, the well pipe and pump water pipe without special requirements (i.e.: steel tube wells, tube wells, Doi ash can be used; in the permit, pressure pipe, hose, plastic pipe can be used for lifting pipe use
3, installation, use, maintenance is simple and easy to cover an area of small, do not need to build pumping station.
4, simple structure, saving raw materials.
Submersible pump is used in the right conditions, proper management and service life has a direct relationship.
