QBY-10 Air-Operated Diaphragm Pump – 0.8 m³/h Compact PP AODD

Where only a small, steady stream of an aggressive fluid needs moving, the QBY-10 is the answer. As the smallest model in the QBY family, its 10 mm (3/8 in) port suits dosing, sampling and tight-space transfer — yet it still self-primes without prime water and runs dry without harm.

Port size	10 mm (3/8 in)
Max flow	0.8 m³/h
Max head	60 m
Suction lift	5 m
Max particle	1 mm
Air consumption	0.3 m³/min (≤7 bar)

Because it is air-driven, there is no motor to burn out if the line runs dry, and no electric spark near flammable media. Body options run from reinforced polypropylene for acids to stainless steel for clean duties.

Applications: chemical dosing, laboratory sampling, printing ink, cosmetics, reagent transfer, small-batch adhesives
