Large Flow Submersible Drainage Sump Pump Explosion Proof 250kW 180hp 80m³/H 480m
250kW 180hp 80m³/h 480m Large-Flow Explosion-Proof Submersible Pump For Mining and Oil Extraction Powerful and Reliable
The BQS series of mining explosion-proof submersible pumps are highly efficient and energy-saving devices specifically designed for mine dewatering and industrial wastewater treatment. This series includes a variety of models to meet different flow rate and head requirements, with power outputs ranging from 1.5 kW to 315 kW. For example, model BQS80-480/4-250/N can provide a head of 480 meters at a flow rate of 80 cubic meters per hour. The BQS pumps feature advanced hydraulic optimization design to ensure optimal performance under various operating conditions. Additionally, these pumps come equipped with automatic control systems that allow them to start and stop automatically without human intervention, significantly reducing labor costs. Their compact design and lightweight structure also make installation and maintenance more convenient.
