What is the 'API' standard related to Centrifugal pumps?

API 610 is the primary API (American Petroleum Institute) standard related to centrifugal pumps used in the petroleum, petrochemical, and gas industries. API standards are widely recognized and used to ensure the safety, reliability, and performance of equipment in these industries. API 610, titled "Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries," specifies the requirements for the design, materials, manufacturing, testing, and inspection of centrifugal pumps. This standard covers a wide range of centrifugal pump types, including overhung, between-bearings, and vertically suspended pumps. API 610 aims to provide a uniform standard for centrifugal pumps to ensure that they meet the stringent requirements of the industries in which they are used. It covers aspects such as hydraulic performance, mechanical design, materials selection, vibration limits, and testing procedures. For example, if a centrifugal pump is being purchased for use in an offshore oil platform, specifying that the pump must comply with API 610 ensures that it meets industry best practices for reliability and safety.
