BQS Mining Flameproof Submersible Pumps
The BQS series overview uses controlled model records for underground mine drainage and dewatering selection. The controlled catalog contains 217 models.
Rated flow, rated head and rated power can be compared from those records.
Final motor, voltage, cable, installation, certificate matching and medium compatibility must be verified for each project before quotation.
Selecting BQS pumps for mine water and sand drainage
Provide flow in m³/h and total head in m at the same required operating point. Check the exact model curve: maximum flow and maximum head are not a simultaneous duty point. Motor rated power is not the actual power consumption at every duty point.
State the liquid, particle size, solids concentration, pH, temperature and wetted-part material requirements. Confirm voltage, frequency, installation depth and cable length. Match the exact model and current certificate to the installation environment before ordering.

Examples from the published BQS catalogue. Compare flow and head at the same rated point, then open the exact model for details. These examples are not a ranking or a site-specific selection.
| Model | Rated flow (m³/h) | Rated head (m) | Rated motor power (kW) |
|---|---|---|---|
| BQS50-15-4/N | 50 | 15 | 4 |
| BQS30-30-5.5/N | 30 | 30 | 5.5 |
