ASME B73.2-2023

Specifications for Vertical In-Line Centrifugal Pumps for Chemical Process

ASME B73.2-2023 is a specification standard specifically designed for vertical in-line centrifugal pumps utilized in chemical processes. Here is an overview of the key aspects of this standard:

Purpose and Scope

• Design and Specification: This standard specifies the design and performance criteria for vertical in-line centrifugal pumps with metallic construction.
• Dimensional Interchangeability: It ensures that pumps from different manufacturers can be interchanged with respect to mounting dimensions, and the size and location of suction and discharge nozzles.
• Facilitating Installation and Maintenance: The standard includes certain design features aimed at simplifying installation and maintenance procedures, enhancing the overall reliability and safety of the pumps.

Key Features

• Single-Stage Design: The standard covers pumps with a single-stage design where the shaft is vertically oriented.
• In-Line Suction and Discharge Nozzles: The pumps have suction and discharge nozzles arranged in-line, which is a critical design aspect for certain chemical process applications.
• Safety and Reliability Enhancements: Design features are incorporated to enhance the operational safety and reliability of these pumps, making them suitable for demanding chemical process environments.

Exclusions

• Maintenance and Operation: The standard does not cover the specific maintenance and operation requirements for these pumps. This focus remains strictly on design and dimensional aspects to ensure compatibility and ease of installation​.
