Problems with mechanical pumps
Thread Content
Could that expert explain in detail the requirements for flushing and cooling the pump?
This topic is a bit broad; if explained in detail, it essentially involves including all the relevant content from the standards. In short, different operating conditions impose varying requirements on mechanical seals and their flushing systems, which can be found in the relevant API standards. Regarding cooling, generally speaking, the pump should be cooled when the temperature of the medium exceeds 120 degrees. In areas with high temperatures, using cooling water is also a good option.
