With a 1-inch port and a strong 7-metre suction lift, the QBY-25 is the first QBY size built to move real particle loads. Its ball-check valves pass solids up to 2.5 mm, so mildly gritty or fibrous fluids no longer mean a blocked pump.
| Port size | 25 mm (1 in) |
| Max flow | 2.4 m³/h |
| Max head | 60 m |
| Suction lift | 7 m |
| Max particle | 2.5 mm |
| Air consumption | 0.6 m³/min (≤7 bar) |
The seal-less, positive-displacement design means the flow rises and falls with backpressure and simply stalls — harmlessly — if the discharge ever blocks, then resumes once it clears.
Applications: chemical transfer, coatings, emulsions, ceramic glaze, adhesives, light wastewater, food pastes
