QJ series submersible electric deep well pump belongs to multi-stage submersible pump for wells. And this series of deep well pump is produced totally according to the national GB/T2816-2014 standard. It adopts a "full floating" impeller structure. When the motor is working, there is no any axial pressure, thus increasing the motor’s service life, moreover the motor is oil-filled motor, the advantage of oil-filled motor is good cooling and lubricity performance. Last the casing and shaft of the pump body are made of stainless steel, which has a certain degree of corrosion resistance.
Product Features
1. The motor and pump body adopt a split structure, which is combined into a whole through a coupling, having the features of interchangeable
2. Adopt high-quality mechanical seal, double seal inside and outside, reliable sealing performance and convenient maintenance
3. The motor is sand-proof and wear-resistance
4. Less power loss, power saving and energy saving
5. Small outer diameter of the pump, large flow, high head, high pumping efficiency
6. The appearance of the pump is very beautiful, the quality is noble, the quality of the inner parts is very strong, and the service life is several times of ordinary well pumps'.
