 BQS price Flameproof explosion-proof submersible pump submersible pump BQS40-50/15/N Flameproof Submersible Sand Pump Sand Pump Explosion BQS sewage submersible sewage pump, air pump BQW coal mine explosion-proof submersible type sewage pump, BQW flushing sewage pump 
 2.2KWBQS structural characteristics of the sewage submersible pump flushing 
 BQS (W) series Flameproof BQS sewage submersible pump flushing with O-shaped rubber ring as static sealing, structural performance, the use of rubber vulcanization curve control technology to protect the O-ring resistant to moisture and anti-aging Quality Seal performance. Dynamic seal uses two sets of mechanical seals, and oil room isolation, effectively turning friction to provide lubrication, the formation of fluid film lubrication protection, while releasing the heat accumulation during exercise, thus extending the service life of mechanical seals to ensure the sealing performance. 
 Pump wetted parts materials with wear-resistant alloy cast iron, pump some fluid mechanical design and balance the use of technology to effectively extend the pump life.
