For high-volume, solids-heavy work the QBY-80’s 3-inch body delivers up to 24 m³/h and swallows solids as large as 10 mm. It is built for dewatering, tank emptying and thick-slurry transfer where a smaller pump would clog or crawl.

It can even be lowered into a pit and run fully submerged, and if the pit empties it simply keeps stroking without damage — no dry-run trip, no burnt motor.
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.
