Which pump should be chosen to transport hydrochloric acid? Feb 20, 2023

Hydrochloric acid is a corrosive liquid widely used in industrial production, and it is one of the three strong acids in industry. Industrial transport of such media, whether high concentration of concentrated hydrochloric acid or low concentration of dilute hydrochloric acid, there are high requirements for special water pump materials, hydrochloric acid pump is not recommended to use metal pumps, generally choose commonly used fluoroplastic material hydrochloric acid transport special pump, basically all plastics are resistant to hydrochloric acid, such as: PP, PE, PVDF, PTFE, FEP, PFA and so on.


IHF horizontal corrosion-resistant hydrochloric acid pump is a single-stage single-suction fluoroplastic alloy chemical centrifugal pump (referred to as IHF fluoroplastic centrifugal pump). It is designed and manufactured according to international standards and combined with the process of non-metallic pump. it is suitable for long-term transportation of any concentration of strong acid, alkali, salt, strong oxidizer and other corrosive medium. its shell is made of polyperfluoroethylene propylene (FEP) lined with metal shell and overflowing parts made of plastic alloy (PTFE, FEP). The pump cover, impeller and shaft sleeve are all made of metal insert wrapped by fluoroplastic integral sintering, the shaft seal adopts external advanced bellows mechanical seal, the static ring adopts 99.9% alumina ceramic (or silicon nitride), and the moving ring adopts tetrafluorine filling material. it has excellent corrosion resistance, wear resistance, high mechanical strength, non-aging and non-toxic decomposition characteristics. The inlet and outlet of the pump are reinforced with cast steel to enhance the pressure resistance of the pump. The pump has the advantages of corrosion resistance, wear resistance, high temperature resistance, non-oxidation, high mechanical strength, stable operation, advanced and reasonable structure, strict and reliable sealing performance, convenient disassembly and maintenance, long service life and so on.


FSB special chemical centrifugal pump for hydrochloric acid transportation is a new type of plastic alloy corrosion-resistant series products carefully designed by Zhonglian pump industry using special pump processing technology. FSB horizontal chemical pump has the advantages of reasonable design, compact structure, reliable performance, convenient use and maintenance, energy saving and so on. It is suitable for transporting media whose physical properties are similar to water at the temperature of 85 ℃-+ 200 ℃: acid, oxidant and corrosive medium (fast hard crystal medium forbidden). The over-current part is all made of plastic alloy (polytetrafluoroethylene and polyperfluoroethylene propylene and other materials) through reasonable formula and molding. The product is widely used in chemical, petroleum, pharmaceutical, pesticide, dye, paint, smelting, papermaking, electroplating, food and other industries. It is an ideal and anticorrosive conveying equipment to put an end to the construction of civilized factories. The pump adopts the most advanced external tetrafluoro bellows mechanical seal, with multi-layer protection, prolonging the service life of the seal, for the transportation of media containing impurity particles, can be equipped with uncooled receipt end face hard to hard (silicon carbide to silicon carbide) mechanical seal, so users need to take into account the solid content in the medium when selecting.
