The QBY-100 tops the range. Its 4-inch port pushes up to 30 m³/h and handles solids to 10 mm, making it the choice for bulk transfer and heavy dewatering where you want a single pump to do the work of several smaller ones.
Port size
100 mm (4 in)
Max flow
30 m³/h
Max head
60 m
Suction lift
7 m
Max particle
10 mm

1.5 m³/min (≤7 bar)
Like every QBY, it needs no foundation and no electricity — just a compressed-air line — so it is quick to deploy on a new line or move to wherever the next job is.
Applications: high-volume wastewater, mining and tailings, dewatering, bulk chemical transfer, cement grout, petrochemical, marine
