PRODUCT OVERVIEW
Designed around the operating conditions.
QBY air operated double diaphragm pumps are driven by compressed air and contain no electric motor at the pump. Flow can be adjusted through the air supply, while body, diaphragm and valve materials are selected around the actual medium.
AVAILABLE PRODUCT TYPES

APPLICATION FIT
Where this series fits—and what to confirm first.
Variable, viscous or solids-containing media where pneumatic drive and flexible control are useful.
For steady low-pulsation delivery of viscous media, review a progressive cavity screw pump.
- Air supply quality and capacity directly affect output.
- Body, ball, seat and diaphragm materials must all match the liquid.
- Actual flow falls as discharge pressure and viscosity increase.
