This Standard covers sealless centrifugal pumps of horizontal end suction single stage and centerline dis-charge design. This Standard includes dimensional interchangeability requirements and certain design fea-tures to facilitate installation and maintenance. It is the intent of this Standard that pumps of the same standard dimensional designation from all sources ofsupply 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, 2, 3, and 4).
