The QBY-15 lifts the QBY-10’s output to 1 m³/h while keeping the same light, portable footprint — no foundation, no wiring. It is a natural fit for low-flow transfer of corrosive or shear-sensitive fluids on benches, skids and mobile carts.
| Port size | 15 mm (1/2 in) |
| Max flow | 1 m³/h |
| Max head | 60 m |
| Suction lift | 5 m |
| Max particle | 1 mm |
| Air consumption | 0.3 m³/min (≤7 bar) |
Flow is set simply by turning the air-supply pressure up or down; there is no variable-speed drive to buy or maintain. The pump also stops by itself if you close the outlet, so it will not overheat when held against a shut valve.
QBY-15 Applications: chemical dosing, cosmetics, printing ink, laboratory transfer, emulsions, fine chemicals
