American Petroleum Institute (API) and Hydraulic Institute (HI) -  Pump Preferred Operating Range (POR) - API 610 and ANSI/HI 9.6.3-2017

• AFT Fathom can help engineers analyze their systems to meet these guidelines. 
• Defines POR from 70% to 120% of flow at the best efficiency point (BEP). In some high-energy pumps the POR is smaller and may only extend from 80% to 115% of flow at BEP.
• Operating a pump within the POR ensures higher reliability and lower energy consumption, reduced maintenance costs.

The API 610 and ANSI/HI 9.6.3-2017 standards are recommended guidelines and not mandatory
