ASME EA-2-2009 (2015) PDF

Full title and description

St ASME EA-2:2009 (R2015) — "Energy Assessment for Pumping Systems". This ASME standard defines a pumping system and sets requirements for organizing, conducting, analyzing and reporting energy assessments of pumping systems (pumps, drivers, drives, piping, valves, controls, instrumentation and related end‑use equipment) to identify opportunities for improved energy performance.

Abstract

Provides requirements for performing a comprehensive pumping‑system energy assessment that considers energy inputs through to work performed, including prescreening, data collection, measurement and analysis, and reporting of findings and recommended actions. The document was originally published as EA‑2:2009 and was reaffirmed as EA‑2:2009 (R2015).

General information

• Status: Superseded / historical reference — this ASME standard has been replaced by the joint international standard ISO/ASME 14414 (2019).
• Publication date: Designation year 2009 (published to the public in January 2010); reaffirmed R2015 (reconfirmation in 2015).
• Publisher: American Society of Mechanical Engineers (ASME).
• ICS / categories: Pumps and pumping systems; fluid systems and components; energy efficiency — commonly referenced under ICS 23.080 / 23.100 and related energy ICS categories.
• Edition / version: ASME EA‑2:2009 (designated 2009), reaffirmed as EA‑2:2009 (R2015).
• Number of pages: 28 pages (standard text).

Scope

Specifies requirements for conducting and reporting pumping‑system energy assessments for open and closed‑loop systems typically used in industrial, institutional, commercial and municipal facilities. The standard focuses on assessing system energy use (primarily electrically driven systems), identifying major efficiency improvement opportunities and documenting findings; it does not prescribe detailed design procedures or implementation steps.

Key topics and requirements

• Definition and boundary of a pumping system (pump(s), driver, drives, piping, valves, controls, instrumentation and end‑use equipment).
• Organizing the assessment: team roles, access, objectives, scope and scheduling.
• Assessment levels and prescreening to prioritise systems for deeper study.
• Data collection and measurement requirements (flow, head/pressure, input power, operating conditions).
• Analysis of measurement data to determine system energy consumption and savings potential.
• Reporting, documentation and recommended action plans (including a prescreening worksheet and appendices for references and guidance).

Typical use and users

Used by energy managers, facility and plant engineers, maintenance and operations personnel, sustainability/ESG teams, energy consultants and auditors to plan and carry out energy assessments of pumping systems and to produce standardised assessment reports and action plans. The standard supports identification of cost‑effective energy savings opportunities.

Related standards

ASME EA‑1 (process heating systems), EA‑3 (steam systems), EA‑4 (compressed air systems), and the companion guidance document EA‑2G (Guidance for ASME EA‑2). This ASME standard has been superseded by ISO/ASME 14414 (2019) — "Pump system energy assessment" — which consolidates and updates the guidance at the international level.

FAQ

Q: What is this standard?

A: ASME EA‑2:2009 (R2015) is an ASME standard titled "Energy Assessment for Pumping Systems" that sets out requirements for organising, conducting, analysing and reporting energy assessments of pumping systems.

Q: What does it cover?

A: It covers the scope and boundaries of pumping systems, prescreening and prioritisation, data collection and measurements (flow, pressure, power), analysis of operating data and preparation of assessment reports and action plans to identify energy‑saving opportunities. It does not specify detailed design or implementation procedures.

Q: Who typically uses it?

A: Energy managers, plant/facility engineers, maintenance managers, operations staff, energy consultants and auditors use the standard to standardise assessments and document findings for management and implementation planning.

Q: Is it current or superseded?

A: EA‑2:2009 was reaffirmed in 2015 (R2015) but is now a historical ASME document; it has been replaced by the joint international standard ISO/ASME 14414 published in January 2019 (ISO/ASME 14414:2019). Users are generally advised to refer to ISO/ASME 14414:2019 for the current international requirements.

Q: Is it part of a series?

A: Yes — EA‑2 is one of a set of ASME energy assessment standards covering major plant systems (EA‑1 process heating, EA‑2 pumping, EA‑3 steam, EA‑4 compressed air) and has an associated guidance document EA‑2G.

Q: What are the key keywords?

A: Pumping system, energy assessment, pump efficiency, flow, head/pressure, motor/drive, measurement, assessment levels, prescreening, reporting.
