LJ Series Vertical Long Shaft Submersible Pump 

Overview 

The LJ series pump is a single-stage single-suction vertical submersible pump. Compared with the YJ pumps, its submerged depth can reach 6 meters. The hydraulic part and the bottom plate of the pump are connected with a cylindrical pipe (column). The discharge pipe is separated from the column. A shaft sealing device is adopted; the bearings are installed in the submerged part of the pump, and the operation status of the mechanical seal is monitored by the oil-water probe.  

It is especially suitable for conveying medium containing solid particles, easily blocked substances and medium which is easy to crystallize and block. According to the size and nature of the solid particles in the medium, the impeller is divided into open impeller and closed impeller, thus solving the problem that the existing long-shaft submersible pump cannot transport the medium containing solid particles and medium easy to crystallize and block.
