Customer's Needs and Problems
Hydrochloric acid containing metal dust and heated to a temperature of 98°C is fed to a concentration analyzer in order to manage the concentration of the hydrochloric acid during the acid cleaning process.
An air-driven diaphragm pump was used, which posed the following problems.
To prevent diaphragm deterioration due to wear and high temperatures, T-branch remote head specifications, in which the hydrochloric acid and the diaphragm do not come into direct contact, were used.
Also, heat-radiation fin specifications were used to prevent the high temperatures from being conveyed to the drive part of the pump.
