Why This Pump Design Works
The QBY uses a simple but effective principle. Compressed air pushes a diaphragm in one chamber while pulling the other diaphragm back. Ball valves open and close to create continuous flow. No rotating parts, no mechanical seal, no leakage paths.
Advantages Over Conventional Pumps
•
No electricity needed — safe for hazardous areas
•
No mechanical seal — zero leak points
•
Self-priming up to 7 meters
•
Can run dry without damage
•
Handles solids up to 10 mm
•
Gentle on shear-sensitive fluids

Common Applications Across Industries
Chemical processing, food manufacturing, mining, wastewater treatment, paint and coatings, pharmaceuticals, ceramics, oil and gas.
Maintenance Philosophy
Fewer parts mean fewer problems. The QBY has only a handful of wearing parts — diaphragms, ball valves, and seats. Replace them when performance drops, and the pump is good as new.
Applications Summary:
chemical processing, food manufacturing, mining, wastewater treatment, paint and coatings, pharmaceuticals, ceramics, oil and gas
