QJ
QJ series submersible pumps are mainly used for extracting groundwa-ter from deep wells and are widely used for irrigation of farmland, water
supply and drainage of cities, industrial and mining enterprises, water supply for human and animal consumption in highlands and mountainous
areas and pressurised water supply for high-rise buildings. The QJ submersible pumps have the advantages of compact structure, small
volume, low noise, no secondary pollution, easy installation and maintenance, safe and reliable operation, high efficiency and energy
saving, and no need to build a pump room.
Flow rate up to 4167 L/min (250 m³/h)
Head up to 615 m
Application Limits
1.380V/50Hz three-phase AC supply;
2.The temperature of the water must not be higher than 20°C;
3.The solids content (by mass) in the water is not greater than 0.01%;
4.The pH of the medium needs to be 6.5 to 8.5;
5.The chloride ion content in the water is not more than 400mg/L;
6.The content of hydrogen sulfide in water is not more than 1.5 mg/L;
7.Submersible electric pumps with a submerged depth of not more than 70m;
The above conditions are the basic use conditions,if the
use conditions are beyond the above range,special production can be made to ensure the
normal operation of the pump.
For example, it can support hot and cold water60HZ motor, etc.
Construction
Motor casing: cast iron/stainless steel (optional)
Pump body: cast iron/stainless steel (optional)
Rotor: 45# round steel, normalized, quenched and tempered
Bearings: water lubricated bearing assemblies and thrust bearing assemblies
Motor: water-immersed motor
Insulation: Class F
