BQS explosion-proof sand pump

The BQS (BQW) series mining explosion-proof sewage and sand discharge submersible electric pump is jointly developed by our company and Jiangsu University. The product specifications are complete, and all products achieve full head and no overload. The company has been committed to technological innovation in its products, solving key technical problems in product structure, parameter optimization, manufacturing process, operating efficiency, sealing and leakage prevention, and material application of submersible pumps for sewage and sand discharge. It has more than 20 patented technologies and has applied multiple latest research results, forming a mature manufacturing process for motors and electric pumps. Compared with similar domestic products, it has the advantages of safety, reliability, lightweight and practicality, good sewage and sand discharge performance, long service life, reasonable spectrum, and convenient selection.

Product features:

1. Model selection: Performance optimization, smooth and unobstructed operation, strong sewage and sediment discharge capabilities, pump with overload free (full range) characteristics, that is, at any operating point, the input power does not exceed the matching motor power. Suitable for various occasions underground in coal mines, it can be used for multiple purposes with one machine.

2. Mechanical seal improvement: adopting independent series mechanical seals and double end mechanical seals.

3. Structural optimization: Structural design is beneficial for the sealing performance of the machine seal, smooth operation, and higher reliability; Optimized design is more lightweight and practical, with low energy consumption, and can operate for a long time without water.

4. IPx8 motor protection level, good cooling effect of submersible motor, lower temperature rise than ordinary motor, further improved durability, F-class insulation, promoting longer service life of motor.
