Air-Operated Double Diaphragm Sand Suction Stainless Steel Pump
Many kind of mini Pneumatic Cylinder Tubing Aluminum ring for Oil free air compressor pump,Used for oxygen concentrators, desiccants, and new energy vehicle engines.motor stator aluminum alloy shell, aluminum alloy molecular sieve cylinder and plastic Sealing. Aluminum alloy honing tube is a specially processed pipe material mainly used in applications that require lightweight and high surface accuracy and dimensional tolerances, such as aerospace, automotive manufacturing, hydraulic systems of engineering machinery, etc. Honing is a precision machining process that uses honing tools with abrasive grains to precision machine the inner holes of metal parts, in order to achieve extremely high roundness, cylindricity, and parallelism, and improve surface roughness. Due to the characteristics of aluminum and its alloys, aluminum alloy honing tubes have advantages such as light weight and strong corrosion resistance compared to traditional steel materials. However, the hardness of aluminum alloy is usually lower than that of steel, so when choosing a honing tube, its application environment and working conditions need to be considered. For example, the "40/50 hydraulic cylinder honing steel pipe" mentioned refers to honing pipes with a diameter of 40mm or 50mm used for hydraulic cylinders, while the "140/168 aluminum alloy honing pipe" refers to larger diameter aluminum alloy honing pipes that may be used in specific industrial applications.

Introduction
The QBK series is an air-operated double diaphragm pump designed for efficient and reliable performance in a wide range of industrial applications. This type of pump operates using compressed air, making it ideal for environments where electrical power is not available or safe to use. It is a positive displacement pump that uses the movement of two flexible diaphragms to move fluids through the system. The pump is particularly useful for handling corrosive, abrasive, and viscous materials, as well as liquids with solid particles.
