    Jiangnan's centrifugal pump with fluoride

      Fluorine-lined centrifugal pump (referred to as IHF centrifugal pump for short) is designed and manufactured in accordance with international standards and combined with non-metallic pump technology. The pump body is lined with metal perfluoroethylene propylene (F46). The pump cover, impeller and shaft sleeve are all sintered and pressed with metal inserts and fluoroplastics. The shaft seal is equipped with an advanced bellows mechanical seal. The ring is made of 99.9% alumina ceramic (or silicon nitride), and the moving ring is filled with PTFE. Its corrosion resistance and wear resistance are excellent. The inlet and outlet of the pump are reinforced with cast steel to enhance the pressure resistance of the pump. The actual application shows that the pump has the advantages of corrosion resistance, wear resistance, high temperature resistance, no aging, high mechanical strength, stable operation, advanced and reasonable structure, strict and reliable sealing function, convenient disassembly and inspection, and long service life.

    Fluorine-lined centrifugal pump

      Because of the particularity of the chemical industry in pump applications, the fluorine-lined centrifugal pumps have the following different design characteristics compared with other centrifugal pumps:

      A). It can adapt to the characteristics of chemical industry anti-corrosion

      Fluorine-lined centrifugal pump conveys materials, everyone knows that the chemical industry materials, raw materials, etc. are mainly corrosive liquids. This requires the application and reasonable selection of material options for chemical pumps to ensure long-term safe, long-term stable and long-life operation of the pump.

      B). Features that can adapt to the process needs of the chemical industry

      In the chemical manufacturing process, fluorine-lined centrifugal pumps not only need to transfer materials but also provide the necessary pressure for the process requirements, but also must ensure the amount of materials transferred. In the chemical manufacturing control, the pump flow and pump head of the demand pump should be stable and maintained The pump operates efficiently and reliably.

      C). It can adapt to the characteristics of high temperature and low temperature in the chemical industry

      The high-temperature materials transmitted by the fluorine-lined centrifugal pump include high-temperature medium materials in the process and heat transfer media generated in the manufacturing process.

      Various types of low-temperature materials transmitted by fluorine-lined centrifugal pumps, such as methane, freon, liquid oxygen, liquid nitrogen, etc.

      Regardless of whether the fluorine-lined centrifugal pump transmits high-temperature or low-temperature materials, the material and construction options are more appropriate, and it must have considerable strength. The design, process, and production of pump parts can withstand thermal shock, high temperature expansion, and low temperature cold shrinkage deformation, cold brittleness Etc.

      D). Can adapt to the characteristics of wear resistance and pressure resistance in the chemical industry

      When the material conveyed by the fluorine-lined centrifugal pump contains suspended solid particles, the impeller and pump chamber of the pump are also running at high flow rate and high pressure. The surface protection layer of the parts of the fluorine-lined centrifugal pump is destroyed and its life is short, so it must be improved The wear resistance and pressure resistance of the fluorine-lined centrifugal pump.

      E). Can adapt to the reliable operation of the chemical industry

      To ensure the reliable operation of the fluorine-lined centrifugal pump: First, there is no obstacle for long-period operation, and second, the various parameters are stable during operation. Reliability of operation plays a crucial role in chemical manufacturing. If the chemical pump often has obstacles and failures, it will not only affect manufacturing, but may also cause chemical accidents. Fluctuations in the speed of chemical pumps can cause fluctuations in pump flow and pump outlet pressure, which can not be carried out correctly in the manufacture of chemical pumps or the materials in the system can not be balanced, which can easily lead to product quality degradation or scrap, resulting in economic losses.

      F). Can adapt to the characteristics of chemical industry without leakage or reducing leakage

      The materials transmitted by the fluorine-lined centrifugal pump are basically explosive, flammable, toxic, harmful, corrosive and other media. If the leakage will seriously pollute the environment, endanger personal safety or cause greater accidents, it is necessary to ensure the operation of the fluorine-lined centrifugal pump There is no leakage from time to time. Jiangnan uses new technology, new materials and new processes on the sealing of the fluorine-lined centrifugal pump, and the high quality ensures no leakage.

      Fluorine-lined centrifugal pump is a machine used to transmit corrosive media. It has high efficiency and can be directly and quickly connected to the motor. It has a simple structure, light body and easy adjustment. It is widely used in chemical manufacturing and daily life.
