Bqw Explosion Proof Submersible Sewage Drainage Pump
BQW explosion-proof mine submersible sewage drainage pump
BQW explosion-proof submersible sewage pump is designed and manufactured in accordance with the flameproof standard.
In the motor part, strict flameproof measures are adopted.
The motor housing is made of cast steel, the rotor shaft is made of stainless steel.
The unit can drain the shallow water on the surface of the working face and also work under the water for a long time.
Electric pump is with compact structure, light and small easy to move, without water diversion, double-sided seal, durable, safe and reliable, strong adaptability and other advantages.
BQW explosion-proof submersible sewage pump is an advanced and reliable drainage tool used in mining, roadway, bottom hole water hole, local water hole, drainage of coal preparation factory, engineering drainage and other occasions.
It is suitable for underground roadway and mining area of coal mine, underground water discharged from other working medium containing methane or explosive gas mixture of coal dust and coal water containing suspended coal powder, and also suitable for explosive environment of petrochemical system.
