2. This pump features two diaphragms that are driven by compressed air to continuously suction and release liquid, making it highly efficient for transferring various types of liquids. It is particularly safe in hazardous environments due to the absence of an electric motor. 3. In addition to handling flowable liquids, the QBY pneumatic double diaphragm pump can also manage difficult-to-pump media. It combines 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.
