1. QBY Stainless Steel Air Diaphragm Pump for Food & Chemical is a new type of transportation equipment that uses compressed air, smoke, and industrial exhaust gas as the power source. 2. This pump features two diaphragms, where compressed air enters the pump body to drive it through continuous suction and release actions, enabling efficient liquid pumping. It's particularly safe in hazardous environments due to the absence of an electric motor. 3. The QBY air-operated double diaphragm pumps can handle both fluid and difficult-to-pump media, combining the advantages of self-priming, submersible, shielded, slurry, and impurity pumps.  Product Details: Performance Data: Size(") Capacity(m³/h) Head(m) Suction Max Grain Dia.(mm) Air  Pressure (Kgf/cm²) 5  Montessori Busy Book,Quiet Book Montessori,Busy Book Montessori,My Preschool Busy Book Guangzhou Xinqicai Printing Co., Ltd. , https://www.cnxqcprinting.com
