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
