2. This pump features two diaphragms, where compressed air drives the pump through continuous suction and discharge actions, making it efficient for pumping liquids. It's particularly safe in hazardous environments because it doesn't use an electric motor. 3. The QBY pneumatic double diaphragm pumps can handle both free-flowing liquids and more challenging media. They combine the advantages of self-priming, submersible, shielded, slurry, and impurity pumps.  Product Details: Performance Data: Size (") Capacity (m³/h) Head (m) Suction Head (m) Max Grain Dia.
