An AV pump, also known as a pneumatic conveying pump or air-assisted conveying pump, is an efficient and reliable solution for moving dry bulk solids across long distances in industrial production lines. It combines the principles of fluidization and pressure differential to transport powders, granules, and other free-flowing materials through enclosed pipelines. The pump is designed to handle a wide range of materials, including cement, fly ash, lime, gypsum, alumina, chemical powders, food ingredients, and many other bulk solids.

At the heart of the AV pump is a robust conveying chamber, typically manufactured from high-grade stainless steel or carbon steel, depending on the application and material characteristics. Stainless steel versions are ideal for corrosive materials, food-grade applications, and environments requiring high hygiene standards. Carbon steel versions offer excellent mechanical strength and cost-effectiveness for general industrial use, especially in cement and mineral processing industries.

The operating principle of the AV pump is straightforward and proven. The pump chamber is filled with material through a top inlet. Once the chamber is full, compressed air is injected through a series of air nozzles and fluidizing pads located at the bottom of the pump. This air stream fluidizes the material, turning it into a dense, fluid-like state. At the same time, the pressure inside the chamber is raised, pushing the fluidized material out through an outlet pipe and into the conveying line. This gentle fluidizing action minimizes particle degradation and equipment wear.

AV pumps are available in a wide range of sizes and configurations to suit different production capacities. From compact units for small batch processing to large-scale pumps for continuous conveying, the design can be tailored to meet specific site requirements. Options include vertical or horizontal configurations, various inlet and outlet sizes, explosion-proof components, and custom control panels. These flexible options allow seamless integration into existing process lines. These systems also offer excellent energy efficiency compared with mechanical conveyors.

The versatility of AV pumps makes them indispensable in many industries. In the cement and construction sector, they transport raw meal, cement, and fly ash. In power plants, they handle fly ash and desulfurization powder. In the metallurgical industry, they convey alumina, carbon black, and other fine materials. Chemical plants use AV pumps for polymer powders, additives, and pigments. Food processing facilities rely on them for sugar, starch, and flour transfer. The pump is also widely used in mining, glass, and environmental protection industries.

As a professional AV pump manufacturer and supplier, our company offers comprehensive solutions that include product selection, system design, installation guidance, and after-sales support. We produce both stainless steel and carbon steel AV pumps with strict quality control. Every unit is tested before delivery to ensure reliable performance under demanding operating conditions. Our engineering team works closely with customers to customize the pump for specific materials, capacities, and pipeline layouts.

When evaluating AV pump price, it is important to consider not only the initial purchase cost but also the long-term operating and maintenance expenses. High-quality materials, precision machining, and reliable automation contribute to a longer service life and fewer breakdowns, which ultimately means lower total cost. We offer competitive pricing and provide detailed quotations based on your exact requirements.
