Description

QJ series high power pump is vertical multi-stage centrifugal pump submerged in water for water supply from pool or deep well. It is not only applied to pool and deep well, but also to industry, farm and agricultural irrigation, mining drainage, water lifting projects, such as river, ditch, reservior. Meanwhile it is used in mountainous area water supply, rainwater recycling system, emergency rescue and disaster relief, urbanwater supply, enterprises and goverment institutions water lifting. Mechanical motor integration, operation in water, safty and realiability rubber bearing liner, No special requirements on well pipe, as long as pipes can bear the pressure Small size, easy installation and maintenance Simple structure, saving raw material Corrosion resistance, Low power consumption Characteristics: High lifting with single stage, short casing and stable operation The diameter of the shaft is bigger than national standard so that they could be operated safely in deep well. The casings are made out of HT**0. Deep well pump bowl/shell is made from ductile cast iron or cast steel, strengthen the bowl/shell’s pressure bearing capacity. The unique designed check valve could effectively prevent the full set from being damaged by the water hammer and dropping into the well. The small axial force could extend the motor’s service life, thus increasing its working efficiency.
