1. The QBY Stainless Steel Air Diaphragm Pump is ideal for use in the food and chemical industries. It is designed to be resistant to chemicals and can operate using compressed air, smoke, or industrial exhaust as a power source. 2. This pump features two diaphragms that are driven by compressed air, allowing it to continuously suck and release liquid, making it easy to transfer various types of fluids. Its design makes it particularly safe for use in hazardous environments since it does not require an electric motor. 3. The QBY air-operated double diaphragm pump is versatile and can handle both flowing liquids and more challenging media. It combines the advantages of self-priming pumps, submersible pumps, shielded pumps, slurry pumps, and impurity pumps, offering a wide range of applications.  Product Details: Performance Data: Size(") Capacity(m³/h) Head(m) Suction Max Grain Dia.(mm) Air  Pressure (Kgf/cm²) 5  Zinc Casting,Auto And Motorcycle Parts,Auto Motorcycle Parts,Communication Product,Integrated Die Casting Products,Aerospace Parts Dongguan Yurun Hardware Products Co., Ltd , https://www.yurunhardware.com
