2. This pump features two diaphragms, where compressed air drives the pump in a continuous suction and discharge cycle, enabling it to easily move liquids. It is particularly safe for use in hazardous environments due to the absence of an electric motor. 3. The QBY pneumatic double diaphragm pumps are not only capable of transferring liquids but can also handle difficult-to-pump media. They combine the advantages of self-priming pumps, submersible pumps, shielded pumps, slurry pumps, and impurity pumps.  Product Details: Performance Data: Size (") Capacity (m³/h) Head (m) Suction Head (m) Max Grain Dia.
