turbines, for use in petroleum, heavy-duty chemical, and gas industry services This standard is based on the accumulated knowledge and experience manufacturers of and usersof centrifugal pumps The objectiveof this standardis to providea purchase specification to facilitate the manufacture and procurement of centrifugal pumps for use in petroleum, chemical, and gas industry services The primary purpose of standard is to establish minimum mechanicalrequirements this This limitation in scope is one of charter as opposed to interest and concern Energy conservation is of concern and has become increasingly important in all aspects of equipment design, application, and operation Thus, innovative energy-conserving approaches should be aggressively pursued by the manufacturer and the user during these steps Alternative approaches that may result in improved energy utilization should be thoroughly investigated and brought forth This is especially true of new equipment proposals, since evalthe uation of purchase options will be based increasingly on total life costs as opposed to acquisition cost alone Equipment manufacturers,in particular, are encouraged to suggest alternatives to those specified when such approaches achieve improved energy effectiveness and reduced total life costs without sacrifice of safety or reliability This standard requires the purchaser to specify certain details and features Although it is recognized that the purchaser may desire to modify, delete, or amplify sections of this standard, it is strongly recommended that such modifications,deletions, andamplifications be madeby supplementing thisstandard, rather than by rewriting incorporatingsections or thereof into another completestandard API standards are published as an aid to procurement of standardized equipment and materials These standardsare not intendedto inhibit purchasersor producers from purchasing or producing products made to other standards API

Further information should be (see shown on the data sheets Appendix B) or stated in the quotation request and purchase order Terms used in this standard are defined in 1.4.1 through 1A.56 1.4DefinitionofTerms 1.1.2 The pump types covered by this standard can be broadly classified as overhung, between bearings, and vertically suspended (see Figure - 1) To aid the use of stanthis dard, Sections 2, 3, 4, and cover requirements that are applicable to two or more of these broad classifications.Section is divided into subsections and covers requirements unique to each of the broad classifications.Figure 1-2 shows the various specific pump types within each broad classification and lists the identification assigned to each specific type 1.1.3 The pump types listed in Table 1-1

The objective of standardization of seal chamber dimensions slightly different from the7th Edition of API Standard 610 is to allow standard seals to be developed for682 and for API due to conversion
