QBY Pneumatic Diaphragm Pump – Air-Driven, Self-Priming, No Electricity Needed

Let me tell you why the QBY pump is worth your attention. It runs on compressed air, so there’s no motor, no electrical wiring, and no spark risk. You can put it in a flammable environment and sleep well at night. It self-primes up to 7 meters and can run dry all day without damage. That alone saves a lot of headaches.

What It Can Handle
The QBY isn’t picky. It pumps thin liquids like water, thick stuff like peanut butter, and everything in between — acids, solvents, slurries, even liquids with solids up to 10 mm. The gentle pumping action doesn’t beat up sensitive materials either.
