scope:

Baseplate requirements covered in this Practice are for horizontal pump designs described in ASME B73.1M and PIP RESP73H and for general purpose pumps. Baseplate dimensional requirements shall be per ASME B73.1M except for free-standing baseplate designs and general purpose pumps that are not of the ASME B73.1M design. If a dimensional conflict arises between this Practice and the ASME B73.1M, this Practice shall take precedence.

Purpose

This Practice provides designers and users with the minimum requirements for ASME B73.1M pump baseplates and baseplates for general purpose pumps that do not fall within ASME B73.1M dimensional and performance envelopes.

Comment: The function of a baseplate is to provide a structure under a pump and its driver that maintains alignment between the two components while accepting published piping loads. A pump properly supported and installed will improve pump reliability and extend the operating life of such components as bearings, couplings, and seals.
