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.
HAQUANPUMP builds the full QBY range in-house. Send us your fluid, flow and head, and we will recommend the exact model, body material and diaphragm for the job.
How much does a QBY air diaphragm pump weigh, how is it packed, and how fast can it ship? Real figures from our orders, plus the spares to order with it.
