product overview

The QJ type submersible electric pump for wells is a water lifting equipment that is directly connected to a motor and a water pump and works underwater. It is suitable for extracting groundwater from deep wells and can also be used for water lifting projects such as rivers, reservoirs, and canals. It is mainly used for irrigation of farmland and water supply for humans and animals in high-altitude mountainous areas, and can also be used for drainage in cities, factories, railways, mines, and construction sites.

Product Features

1. The motor and water pump are integrated for safe and reliable operation when submerged in water.

2. There are no special requirements for well pipes and lifting pipes (i.e. steel pipe wells, ash pipe wells, soil wells, etc. can all be used; under pressure permission, steel pipes, rubber hoses, plastic pipes, etc. can all be used as lifting pipes).

3. Easy to install, use, and maintain, with a small footprint and no need to build a pump room.

4. Simple structure and material saving.

The suitability of the operating conditions and proper management of submersible electric pumps are directly related to their service life.
