Acid pump should be how to choose it? The following is a common selection of acid pump instructions: 1, hydrochloric acid pump commonly used hydrochloric acid maximum concentration of 38%, its nature is corrosive, the proportion is not large. If there is no impurity in the medium, it is recommended to choose leak-free CQB fluorine plastic magnetic pump; if there is a small amount of impurities, it is recommended to use a relatively good resistance to corrosion IHF lining fluorine centrifugal pump; Wear-resistant wear-resistant mortar UHB-ZK; 2, sulfuric acid pump with sulfuric acid pump is divided into sulfuric acid pump and concentrated sulfuric acid pump, the former a larger range of options, dilute sulfuric acid pump can choose engineering plastics pump, F46 pump , F26 pumps, the latter (concentrated sulfuric acid pump) can only choose Fluoroplastics (F46) pump, because concentrated sulfuric acid will corrode the common engineering plastics, but the fluorine plastic will not be corroded. Also note that the high density of concentrated sulfuric acid, pump power when the pump should pay attention to the allocation of large, simple algorithm for the "shaft power" * 1.84 is the shaft power delivery concentrated sulfuric acid. 3, hydrofluoric acid hydrofluoric acid is very corrosive, it is recommended to use fluorine plastic magnetic pump, (and must be the series of ceramic pump parts replaced by hydrofluoric acid) 4, nitric acid pump also recommended the use of nitric acid Fluorine plastic magnetic pump, and rubber seals to be replaced by PTFE material. 5, acetic acid It is one of the most corrosive substances in organic acids, ordinary steel in all concentrations and temperatures of acetic acid will be severely corrosive, stainless steel is an excellent anti-acetic acid material, 316 stainless steel containing molybdenum can also be suitable for high temperature and Dilute acetic acid steam. For high temperature and high concentration of acetic acid or other corrosive media and other harsh requirements, the choice of high-alloy stainless steel or fluorine plastic magnetic pump. Such as CQB magnetic pump, CQ316L stainless steel magnetic pump 6, brine (seawater) Ordinary steel in sodium chloride solution and seawater, salt water corrosion rate is not too high, the general shall be used paint protection; all kinds of stainless steel also have a low uniform corrosion rate, But may cause localized corrosion due to chloride ions, it is recommended to use fluoroplastic centrifugal pumps, such as IHF-type fluoroplastic centrifugal pump, you can also choose a leak-free fluorine plastic magnetic pump. 7, Sealed seal form: Magnetic pump is a static seal, so you can not consider the sealing, and centrifugal pumps generally use external bellows mechanical seal, the corrosion resistance and wear resistance are better, such as the delivery of the media containing particles, then Hard to hard mechanical seals can be used.
