Chemical process pump manufacturers: A brief introduction to chemical process pumps.

Chemical process pumps are a general term for various pumps used in chemical production. These pumps have high power, high speed, small size, simple structure, and are easy to maintain. However, they operate at high temperatures, are prone to wear, and have a high maintenance factor. Therefore, maintaining and servicing these pumps can be relatively difficult. To reduce the frequency of major repairs, it is essential to perform proper maintenance and upkeep of the equipment.

Selection of materials for metallurgical chemical pumps

The selection of pump materials is crucial for the reliability of pumps, especially those used in refineries and chemical plants, which often operate under conditions that are flammable, explosive, highly corrosive, high temperature, and low temperature. Therefore, both China and the United States have established standards. Of course, the correct and economical selection of materials also requires rich experience and a keen awareness of the latest research and development of materials both domestically and internationally.
