Once flow and solids climb beyond what a 1.5-inch pump handles comfortably, the QBY-50’s 2-inch body takes over. It moves up to 12 m³/h and passes solids to 8 mm, making it a workhorse for slurry, sludge and thicker process fluids.
Port size
50 mm (2 in)
Max flow
12 m³/h
Max head
60 m
Suction lift
7 m
Max particle
8 mm
Air consumption
0.9 m³/min (≤7 bar)
With no shaft seal and no close-fitting parts, abrasive media wear the pump only slowly, and there is nothing to leak — a real advantage when the fluid is toxic or corrosive.
Applications: wastewater and sludge, mining slurry, ceramics, chemical processing, cement grout, paint, petrochemical
