(a) This Standard is a design and specification stan-dard that covers metallic and solid polymer centrifugal pumps ofhorizontal, end suction single stage, centerline discharge design. This Standard includes dimensional interchangeability requirements and certain design fea-tures to facilitate installation and maintenance and to enhance reliability and safety of B73.1 pumps. It is the intent of this Standard that pumps of the same standard dimension designation from all sources of supply shall be interchangeable with respect to mounting dimen-sions, size, and location of suction and discharge noz- zles, input shafts, baseplates, and foundation bolt holes (see Tables 1-1 and 1-2). Maintenance and operation requirements are not included in this Standard.
(b) This Standard has been revised to include solid polymer pumps formerly covered under ASME B73.5.The design and construction features for metallic pumps are covered in section 5. The design and construction features for solid polymer pumps are covered in section 6. This Standard must be read in its entirety for proper application.
