scope:

This standard applies to IOM manuals for rotodynamic (centrifugal) pumps, including the following:

a) Overhung impeller, rigidly-coupled pumps (OH4, OH5, OH5A, OH6, OH7, OH8A, and OH8B).

b) Horizontal, flexibly coupled, axial flow, single stage, overhung design (OH00).

c) Overhung impeller, separately coupled pumps (OH0, OH1, OH1A, OH2, OH3, and OH3A).

d) Sealless centrifugal pumps (OH9, OH10, OH11, and OH12).

e) Between-bearing, separately coupled, single-stage pumps (BB1 and BB2).

f) Between-bearing, separately coupled, multistage pumps (BB3, BB4, and BB5).

g) Vertically suspended, separate discharge (sump), volute style (VS4 and VS5).

h) Regenerative turbine pumps (RT1, RT2, RT3, and RT4).

i) Special-effects pumps (Pitot tube, etc.)

For instructions on sealless rotodynamic pumps, see ANSI/HI 5.1-5.6 Sealless Rotodynamic Pumps for Nomenclature, Definitions, Application, Operation and Test.

The standard outline shall be used when writing IOM manuals. The subtopics within each section shall be addressed when appropriate for the specific pump.

Installation, operation, and maintenance manuals shall be comprised of 10 sections. Each section must appear in the IOM manual in the sequence shown. The topics that appear under each section may be combined and/or arranged to meet the specific needs of the product being addressed, although every effort shall be made to remain logical and consistent. For example, in Section A.1, the explanation of safety designations should precede specific safety warnings for a product. Not all of the topics listed need to be included in the IOM manual for all products; the manufacturer will be given the latitude to decide if a particular topic is applicable.
