The primary purpose of API RP 697 is to provide minimum recommendations for the inspection and repair of centrifugal pumps built to the API 610 standard, specifically types OH1 through OH5 and BB1 through BB5. While its core focus is on these specific pump designs, its guidelines are so robust that they are considered generally applicable to all types of pumps, offering a best-practice benchmark for the entire industry.
Running clearances must conform strictly to API 610 tables. Standard practice dictates increasing the diametral clearance by 0.125 mm (0.005 inches) for operating temperatures above 260°C (500°F) to account for thermal expansion. Dynamic Balancing
Covers the minimum requirements for centrifugal pumps used in petroleum, petrochemical, and natural gas industries.
