Mining Flameproof Submersible Electric Pumps

The BQW explosion-proof submersible electric pump for mining applications consists of a single-stage or double-suction multistage centrifugal pump paired with a water-cooled, explosion-proof submersible motor designed specifically for mining use. The pump features an external mounting configuration, with the pump positioned above the motor—making it an "upper-pump" design—and both components are connected via a coupling. The entire unit is fully submerged in water during operation, and an additional suction hood helps efficiently cool the motor. This pump-motor assembly can be installed either vertically, horizontally, or at an inclined angle, offering versatile deployment options for various mining environments.

Product Features
High Efficiency and Energy Savings: Featuring an optimized electromagnetic design for the submersible motor, which delivers high motor efficiency, combined with a highly efficient hydraulic model that maximizes pump performance—resulting in significant overall energy savings for the entire unit.
Safe and Reliable: The motor is completely filled with water and designed with an explosion-proof structure. An additional water-absorbing cover ensures optimal surface flow, enabling efficient heat dissipation, effectively reducing temperature rise, enhancing reliability, and extending the motor's service life.
Easy to install and operate: The unit has low requirements for underground installation conditions, requiring minimal infrastructure work in the mine tunnels. It can run in vertical, horizontal, or inclined positions, allowing flexible placement in suitable drainage locations—making it highly versatile and widely applicable.
Advanced and Reliable Technology: The long rotor of the high-power motor features our company’s proprietary intermediate support bearing technology, significantly enhancing the motor’s operational reliability. Additionally, a new bearing design and advanced materials are employed to withstand substantial axial forces, ensuring extended service life for the entire unit.
Application
Suitable for normal production drainage, emergency rescue drainage, and mine restoration drainage in mines with hazardous environments containing gases or coal dust explosions.
