Full title and description
ASME B73.3-2015 — Specification for Sealless Horizontal End Suction Centrifugal Pumps for Chemical Process. This design and specification standard covers metallic (and plastic-lined) sealless centrifugal pumps of horizontal, end-suction, single-stage, centerline-discharge configuration and specifies dimensional interchangeability and selected design features to facilitate installation, maintenance and safe operation.
Abstract
Defines nomenclature, dimensional interchangeability, design and construction features, documentation requirements and data-sheet items for sealless horizontal end-suction centrifugal pumps used in chemical process service. The standard aims to ensure that pumps of the same standard dimensional designation are interchangeable with respect to mounting dimensions, nozzle sizes/locations, shafts, baseplates and foundation bolt patterns.
General information
- Status: Superseded (replaced by ASME B73.3:2022).
- Publication date: 2015 (commonly cited as December 15, 2015 / 2015 Edition).
- Publisher: American Society of Mechanical Engineers (ASME).
- ICS / categories: 23.080 — Pumps (Fluid systems and components for general use).
- Edition / version: 2015 edition (ASME B73.3-2015).
- Number of pages: ~54 pages (commonly listed by standards distributors).
Scope
Applies to sealless horizontal end-suction, single-stage, centerline-discharge centrifugal pumps intended for chemical process service. The standard covers requirements for dimensional interchangeability, selected materials and construction features, mounting and nozzle arrangements, documentation (including a mandatory data sheet), and optional electronic data exchange formats. It does not cover pump operation, in-service maintenance procedures or detailed rotating-equipment testing beyond specified dimensional and design criteria.
Key topics and requirements
- Dimensional interchangeability requirements (mounting, suction/discharge nozzle locations and sizes, shaft/input arrangements) to promote cross-manufacturer compatibility.
- Design and construction features specific to sealless pump types (mag-drive / canned-motor / containment shell arrangements and metallic or lined wet-end materials).
- Material specifications and selection guidance appropriate for chemical process service.
- Mandatory pump data sheet content and recommended documentation practices (including a mandatory appendix data sheet and a non-mandatory electronic data exchange appendix).
- Notes on alternative designs and limitations; references to related pump and nozzle-load guidance where applicable.
Typical use and users
Used by pump manufacturers, specification engineers, procurement/purchasing agents, consulting and design engineering firms, and end-users in the chemical, petrochemical and allied process industries when specifying or purchasing sealless horizontal end-suction pumps and when ensuring dimensional interchangeability between suppliers. It is also used as a reference for mechanical design interfaces (foundations, piping connections, baseplates).
Related standards
Closely related to other B73 series documents (ASME/ANSI B73.1 and B73.2 for horizontal and vertical designs), Hydraulic Institute / ANSI guidance on nozzle loads (e.g., ANSI/HI 9.6.2 and related HI documents), and other pump standards such as API and ISO pump specifications where interface or application overlap exists. The 2015 edition was formally superseded by ASME B73.3:2022.
