The issue of centrifugal pump types and maximum allowable pressure
Thread Content
What are the types of single volute, multi-volute, and guide vanes in the API data sheet for centrifugal pumps? Should the temperature corresponding to the maximum allowable pressure be the pumping temperature when the pump is operating normally? Higher temperature again?
1. Guide vanes are not a standard feature of centrifugal pumps per API 610. In terms of my personal work experience, I have not seen any API centrifugal pumps equipped with guide vanes ； 2. The temperature corresponding to the maximum allowable pressure should be the highest permissible temperature for the pump; refer to clauses such as API 5.3.3, 5.3.4, and 5.3.5.
