What are the obvious characteristics of acid resistant pumps

The main reason why Dalian acid resistant pumps can resist acid is the material of the pump. Generally, non-metallic materials are used as the overcurrent components of acid resistant pumps, such as "polyethylene, polypropylene, perfluoroalkoxy, etc." Among them, perfluoroalkoxy is one of the good acid resistant materials, which can basically resist the corrosion of any acidic medium and is known as the plastic king. Magnetic pumps are in the form of static seals, so there is no need to consider sealing performance. Centrifugal pumps generally use external corrugated pipe mechanical seals, which have good corrosion and wear resistance. If the conveyed medium contains particles, hard to hard mechanical seals can be used. Hydrofluoric acid is highly corrosive. It is recommended to use fluoroplastic magnetic pumps, and the ceramic parts of this series of pumps must be replaced with materials that are resistant to hydrofluoric acid.

Firstly, acid resistant pumps are used to transport corrosive or non polluting media, and are only suitable for transporting various corrosive media under temperature conditions of -20 ℃ to+120 ℃. Corrosive media commonly used include sulfuric acid, hydrochloric acid, nitric acid, acetic acid, alkali, ammonia, salt water, etc. Due to different concentrations, their corrosion strength also varies. Therefore, more attention should be paid during use. There are generally three types of corrosion-resistant diaphragm pumps: pneumatic diaphragm pumps, electric diaphragm pumps, and hydraulic diaphragm pumps. The QBK pneumatic diaphragm pump is one of the high-quality corrosion-resistant diaphragm pumps. This pump has a long service life and can pump flowing liquids as well as transport some non flowing media. It combines the advantages of self suction pumps, submersible pumps, shielded pumps, mud pumps, and impurity pumps in one conveying equipment.
