Description
Introduction
QJ series submersible pump for wells is a water pumping device that directly connects the motor and the pump and operates underwater. It is suitable for extracting groundwater from deep wells, and can also be used in water pumping projects such as rivers, reservoirs, and canals. It is mainly used for irrigation in farmlands and for water supply for people and livestock in high-altitude mountainous areas. It can also be used for water supply in cities, factories, railways, mines, and construction sites.
