Application of ASME B73.2-2023 Specification for Vertical In-Line Centrifugal Pumps for Chemical Process
This Practice supplements ASME B73.2-2023, Specification for Vertical In-Line Centrifugal Pumps for Chemical Process. Together, this Practice and ASME B73.2-2023 provide requirements to the manufacturer for design and manufacture of vertical in-line centrifugal pumps.
This Practice describes additions, changes, and/or deletions to the requirements in ASME B73.2-2023. The section/paragraph numbers and the associated headings used in this Practice correspond to those used in ASME B73.2-2023. Because this Practice does not take exception to all the requirements in ASME B73.2-2023, the section/paragraph numbers in this Practice may not be sequential.

Liquid Ring Vacuum Pumps and Compressors Specification
This Practice provides the requirements for liquid ring vacuum (LRV) pumps and compressors, drivers, and associated equipment.
This Practice describes the standard arrangement for liquid ring vacuum pumps and compressors and systems employing liquid ring machines. This Practice provides a framework for specifying a skid- mounted liquid ring machines system, “package,” for systems with drivers less than or equal to 150 kW (200 hp). This Practice can be applied to simple once-through arrangements, partial recirculation, and total recirculation systems.
Comment: This Practice can be used in conjunction with API 681.
A liquid ring machine data sheet, RESP004-DM/D, is included with this Practice. This data sheet may be used to communicate purchaser requirements; however, supplemental information may be necessary to fully define process requirements.
Vendor websites provide excellent visualizations of how LRV machines operate.
