The particularity of sodium chloride in soy sauce, with its severe corrosiveness and the loss of rust prevention and wear resistance in overcurrent components due to long-term contact. Hollysys rotor pump, considering the characteristics of soy sauce medium, has made the following customization and treatment for the rotor pump. Therefore, in Hollysys service engineering, special process treatments have been applied to all parts that come into contact with the material, not only effectively preventing corrosion but also increasing wear resistance and extending service life. This unobstructedly improves production efficiency while effectively maintaining the traditional flavor and aroma of soy sauce. At the same time, the product has strong self-priming capabilities, stable conveying, low pulsation, and minimal vibration, and is widely used in the finished soy sauce production process.
