The QBY-40 is the model most buyers reach for first — a 1.5-inch all-rounder that covers the bulk of everyday transfer duties at up to 8 m³/h. It carries solids to 4.5 mm and lifts 7 m dry, so it copes with everything from clean chemicals to lightly laden slurries.
| Port size | 40 mm (1.5 in) |
| Max flow | 8 m³/h |
| Max head | 60 m |
| Suction lift | 7 m |
| Max particle | 4.5 mm |
| Air consumption | 0.6 m³/min (≤7 bar) |
If you are unsure which size to standardise on across a site, the QBY-40 is usually the safe starting point: common spares, wide material choice, and enough head and solids capacity for most lines.
Applications: chemical processing, paint and coatings, ceramics, adhesives, food and beverage, wastewater, light mining slurry
