QD-J,QX-J type submersible electric pump for engineering useDetailed product description：

QD-J and QX-J submersible electric pumps are products developed based on QDX and QX submersible electric pumps, respectively, suitable for specialized applications. Both are single-stage pumps with an external structure. The pumps are coaxially connected to single and three-phase asynchronous motors, but the impellers use high-efficiency semi open impellers that are not easily blocked. It has the advantages of small size, light weight, convenient use, and durability. The electric pump is equipped with a complete motor protection device and a wear-resistant double end mechanical seal. When the impeller of the electric pump is stuck, overloaded or dehydrated, the power supply voltage drops greatly, and the sediment and impurities in the water are too high, the electric pump can be reliably protected in harsh environments.

QD-J and QX-J submersible pumps for engineering are not only suitable for use in QDX and QX submersible pump applications, but also particularly suitable for conveying sewage containing solid impurities with a volume ratio of 2% or even 4% and particles smaller than 7mm. They are used in applications such as mud water discharge in civil construction or other engineering sites, sewage pumping and discharge in industrial and mining enterprises, water supply and drainage and sprinkler irrigation in small farmland and gardens, flood season drainage, etc.
