This pump features two diaphragms, which are driven by compressed air to perform continuous suction and discharge actions. As a result, it can easily handle various types of liquids, including those with high viscosity or containing solids. Its pneumatic design eliminates the need for an electric motor, making it safe and reliable in explosive or flammable conditions. The QBY series pumps are versatile and can transport both free-flowing and difficult-to-move media. They combine the advantages of self-priming pumps, submersible pumps, shielded pumps, slurry pumps, and impurity pumps, making them suitable for a wide range of applications in industries such as chemical processing, oil and gas, and water treatment.  Product Details: Performance Data: Size (") Capacity (m³/h) Head (m) Suction Head (m) Max Grain Dia.
