Full title and description

API RP 697-2023 — Pump Repair. Recommended Practice providing industry guidance for inspection, scope definition, shop and field repair, reassembly, reinstallation and start‑up of pumps used in petroleum, petrochemical and natural gas facilities. First edition, published by the American Petroleum Institute as an overarching recommended practice for pump repair across API 610 pump types.

Abstract

API RP 697 establishes minimum recommended practices for assessing damage, defining work scopes, performing inspections and repairs in both field and shop environments, and returning pumps to service. It is intended to improve safety, reliability and emissions performance by standardizing repair practices and capturing best practices for common centrifugal pump types covered by API 610.

Scope

Provides recommended minimum practices for inspection and repair of centrifugal pumps principally those covered by API 610 (types OH1–OH5 and BB1–BB5). The document covers the full repair lifecycle from initial discovery and field inspection through shop inspection, component repair or replacement, reassembly, reinstallation and start‑up. Some specialized services (for example pumps in hydrofluoric acid service) may require additional, service‑specific methods outside the RP’s scope.

Key topics and requirements

• Guidance on field inspection and damage assessment to define repair work scopes.
• Shop inspection procedures, acceptance criteria and measuring/reporting requirements.
• Repair, refurbishment and manufacturing of replacement components, including tolerances and material considerations.
• Reassembly, balancing, alignment, testing and commissioning practices for repaired pumps.
• Documentation, traceability, and quality assurance for repair actions.
• Health, safety and environmental considerations to reduce incidents and emissions during repairs and restart.
• Interaction and applicability with API 610 pump design requirements and other rotating‑equipment RPs (e.g., RP 687 for rotors).

These topics summarize the principal subjects addressed by the RP and reflect its aim to standardize repair practices and improve reliability and safety.

Typical use and users

Used by plant maintenance and reliability engineers, rotating‑equipment and rotating‑machinery repair shops, original equipment manufacturers (OEMs), inspection and testing providers, procurement/specification teams, and operators in refining, petrochemical, LNG and pipeline sectors who manage pump repairs and return‑to‑service activities.

Related standards

Intended to be used alongside API 610 (Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries) and complements API RP 687 (Rotor Repair). It also interacts with other API equipment and inspection RPs and common industry materials and testing standards referenced within the RP.
