Description / Abstract:
(a) This Standard is a design and specification
standard that covers metallic and solid polymer centrifugal pumps
of horizontal, end suction single stage, centerline discharge
design. This Standard includes dimensional interchangeability
requirements and certain design features 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 dimensions, size, and
location of suction and discharge nozzles, 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.
