Standard for pump couplings: API671 or API610

Thread Content

What are the main differences between using the API671 standard and the API610 standard for pump couplings?
Reply #2 2018-04-09
API671 is a coupling designed for special purposes in refineries, and it is generally used in critical machinery such as large-scale units like centrifugal compressors and rotary compressors. It is rarely used in centrifugal pumps, which instead rely on standards such as ISO14691 or API610. SH/T3171 specifies the scope of application of API671 in pumps: those with a power output of over 1 MW or a rotational speed of over 4000 rpm.
