The QBY-100 tops the range. Its 4-inch port pushes up to 30 m³/h and handles solids to 10 mm, making it the choice for bulk transfer and heavy dewatering where you want a single pump to do the work of several smaller ones.
| Port size | 100 mm (4 in) |
| Max flow | 30 m³/h |
| Max head | 60 m |
| Suction lift | 7 m |
| Max particle | 10 mm |
| Air consumption | 1.5 m³/min (≤7 bar) |
Like every QBY, it needs no foundation and no electricity — just a compressed-air line — so it is quick to deploy on a new line or move to wherever the next job is.
Applications: high-volume wastewater, mining and tailings, dewatering, bulk chemical transfer, cement grout, petrochemical, marine
