QBY Air Operated Double Diaphragm Pump

Features
The operation of the QBY Air Operated Double Diaphragm Pump is simple and reliable, requiring only the opening or closing of the air valve.
This immersible diaphragm pump is designed to avoid damage even if the machine shuts down suddenly or operates without medium for an extended period.
Equipped with a self-protection device, the pump will automatically stop in case of overload. Once the load returns to normal, the abrasion-resistant diaphragm pump will automatically restart.
With a simple structure and fewer wear parts, the QBY Air Operated Double Diaphragm Pump is easy to install and maintain.
Since the medium being transported does not contact the rotor, piston, gear, or vane, the performance is unaffected by the abrasion of these quick-wear parts.
Its outstanding abrasion resistance makes it ideal for delivering mud and impurities.
It requires no electricity, making it suitable for use in flammable and explosive environments.
The membrane pump can be immersed in the medium.
Notably, even without the need for lubricating oil, the pump will not be damaged by idling.
