Fluorine-lined pumps are a specialized type of chemical pump that features a protective layer of fluoropolymer material, such as PTFE or F46, to resist corrosion from harsh chemicals. These pumps are commonly used in industrial applications where the transported media is highly corrosive. Depending on their design, fluorine-lined pumps can be categorized into centrifugal, magnetic, and self-priming types. The pump body typically consists of a metal shell lined with fluorine plastic, while key components like the impeller and pump cover are made using a high-temperature molding process that integrates fluorine plastic around a metal insert.
With the rapid expansion of China’s chemical and petrochemical industries, the demand for fluorine-lined pumps has surged significantly. In 2013, trade data showed a notable increase in both inquiries and orders for these pumps compared to previous years. Industry experts suggest that this growth is driven by the rising number of chemical production facilities and the need for reliable equipment capable of handling aggressive substances.
According to Li Jianwu, Sales Director at Shanghai Hongdong Pump Manufacturing Co., Ltd., the popularity of fluorine-lined pumps is also due to the limited number of domestic manufacturers capable of producing high-quality lined pumps. While several companies have entered the market, only a few have established a strong reputation for consistency and durability. Anhui-based manufacturers, for instance, have shown promising performance in recent years.
The increase in construction projects across various sectors—such as chemicals, coal chemistry, energy, papermaking, textiles, and food processing—has further fueled the demand for fluorine-lined pumps. During China's "Twelfth Five-Year Plan," the country focused on accelerating industrial development, which in turn boosted the pump industry. As a critical component in many industrial processes, fluorine-lined pumps have become an essential choice in chemical plants and other demanding environments.
These pumps are widely used in the transportation of corrosive liquids such as hydrochloric acid, sulfuric acid, hydrofluoric acid, nitric acid, aqua regia, strong alkalis, and powerful oxidizing agents. They can operate effectively within a temperature range of -20°C to 120°C, making them ideal for a wide range of applications in pharmaceuticals, petroleum, electroplating, dyeing, pesticide production, papermaking, and food processing. Their durability and resistance to chemical degradation make them a preferred solution for long-term, high-stress operations.A hydraulic hose is a flexible tube made of synthetic rubber, thermoplastic or reinforced with wire or textile braid. It is used to transmit hydraulic fluid under high pressure to various hydraulic components such as cylinders, valves, and pumps. Hydraulic hoses are designed to withstand high pressure, extreme temperatures, and various types of fluids, including oil, water, and hydraulic fluids. They are commonly used in industries such as construction, agriculture, mining, and manufacturing. Hydraulic hoses come in different sizes, lengths, and pressure ratings to suit different applications.
