What Are the Pump Types Suitable for Conveying Hydrofluoric Acid Medium?

HF Pump Selection

For the transportation of hydrofluoric acid, the model selection and use of the pump are very different from other highly corrosive media.

Hydrofluoric acid is an aqueous solution of fluoride gas, which is colorless and transparent to light yellow smoking liquid.

The mainstream pump industry is divided into two types: fluoroplastic material and metal material. Hydrofluoric acid itself has irritating gas. It has a weak acidity, but the ionization degree when it is concentrated is more significant than when it is diluted, which differs from the general weak electrolysis system. It is highly corrosive and causes severe damage to teeth and bones. It is highly corrosive to silicon compounds. It would help if you stored it in an airtight plastic bottle. Hydrofluoric acid is non-flammable, highly toxic, corrosive, and irritating. Fluoroplastic self-priming pumps, fluoroplastic magnetic pumps, and fluoroplastic centrifugal pumps are resistant to hydrofluoric acid and are not corroded.

If there is a leak of hydrofluoric acid, the personnel in the leaked contaminated area should be quickly evacuated to a safe area and isolated, and access should be strictly restricted. It is recommended that emergency responders wear self-contained buoyant pressure breathing apparatus and acid-alkali-proof work clothes. Do not come into direct contact with spillage. Cut off the source of leakage as much as possible to prevent entry into restricted spaces such as sewers and flood drains. You can mix it with sand, dry lime, or soda ash. You can also wash it with a large amount of water, dilute it with the washing water, and put it into the wastewater system. If there is leakage in the transport of hydrofluoric acid, it will significantly impact the production and operation of the entire factory. After the development of modern science and technology, the characteristics of fluoroplastic self-priming pumps, fluoroplastic centrifugal pumps, and other pump types are: to prevent running, running, dripping, The phenomenon of leakage has been eliminated, environmental pollution has been eliminated, and a "leak-free workshop" and "leak-free factory" have been created. It is an ideal pump for conveying a hydrofluoric acid medium.

The main problem of traditional metal corrosion-resistant pumps is that they cannot completely solve the leakage and leakage phenomenon in the conveying process. Moreover, there is still a gap between the corrosion resistance and fluoroplastic F46, and the mechanical structure design of the metal pump itself is relatively backward, which is very troublesome in daily maintenance. It is even more troublesome to disassemble and repair. The various pump types made of fluoroplastics have their advanced structure and are very convenient for daily maintenance and repair, saving much money for enterprises.
