ASTM F2798-09(2023) PDF

Overview

ASTM F2798-09(2023) is the standard specification for sealless lube oil pumps with oil-through motors, specifically designed for marine applications. Issued by ASTM International, this standard outlines comprehensive requirements for the design, construction, testing, and documentation of canned lube oil pumps (CLPs). These pumps feature rotary positive displacement technology and are engineered to operate in rigorous shipboard lubricating oil service environments, handling oils within the SAE 20–50 viscosity range.

This specification aims to ensure performance, reliability, and safety for marine applications, and supports international harmonization of marine equipment standards in alignment with World Trade Organization (WTO) principles.

Key Topics

• Product Scope: The standard covers sealless, rotary positive displacement canned lube oil pumps (CLPs) equipped with oil-through motors, addressing both the pump and motor as a unified assembly.
• Performance Criteria: Focuses on sustained performance during ship operation-withstanding inclinations, vibration, self-priming capability, and integration with oil and air management systems.
• Material Requirements: Specifies acceptable materials for core pump and motor components (iron, steel, bronze, copper alloys, etc.), referencing leading ASTM material standards to ensure durability and compatibility with marine lubricating oils.
• Testing and Certification: Requires hydrostatic pressure testing, mechanical running tests, and optional certified performance tests to validate safety, leakproof operation, and compliance with rated capacity and airborne noise limits.
• Ordering and Documentation: Details robust documentation needs, including engineering drawings, installation instructions, maintenance manuals, and lists of recommended spare parts.
• Safety and Compliance: Stresses the user’s responsibility in following appropriate safety, health, and environmental practices, along with adherence to regulatory limitations.

Applications

• Marine Ship Systems: CLPs as specified in ASTM F2798 are vital components in lubricating oil systems for naval and commercial ships, ensuring lubrication and motor cooling under demanding marine conditions.
• Critical Machinery Protection: The standard’s requirements for self-priming, air handling, and vibration control contribute directly to safe and reliable operation of engines, turbines, and other shipboard equipment.
• Naval and Defense Sector: Supplementary requirements are provided for military applications, especially for U.S. Navy vessels, emphasizing shock and vibration resistance, material quality, and compatibility with military specifications.
• Aftermarket and Upgrades: The specification supports both OEM installations and the replacement or upgrade of existing marine lube oil pumps, facilitating improved reliability and maintenance efficiency.
