Overview

ASTM F2798-09(2023): Standard Specification for Sealless Lube Oil Pump with Oil Through Motor for Marine Applications provides comprehensive requirements for the design, construction, and testing of sealless, rotary positive displacement pumps-referred to as canned lube oil pumps (CLP)-utilized in shipboard lubricating oil service. The standard covers pumps equipped with oil-through motors that use the handled oil for both lubrication and cooling of internal components.

Developed by ASTM International, this specification ensures reliability, safety, and operational efficiency within harsh marine environments. It applies to CLPs for pumping lubricating oil rated SAE 20 to 50 and stipulates all measurements in inch-pound units. This standard supports compliance with international standards principles outlined by the World Trade Organization’s Technical Barriers to Trade (TBT) Committee.

Key Topics

• Scope and Applicability

  • Establishes requirements for design, construction, testing of marine CLPs.
  • Targets positive displacement sealless pumps with oil-through motors in lubricating oil service.
  • Restricts use to oils rated SAE 20–50.

• Pump and Motor Design

  • Outlines allowable pump types: screws with/without timing gears, vane, and sliding shoe designs.
  • Specifies oil-through motors for bearing lubrication and winding cooling.
  • Requires features such as self-priming capability, flanged connections, and ability to handle up to 8% entrained air.
  • Mandates minimized airborne noise and vibration under operational conditions.

• Material and Construction

  • Details materials for primary pump and motor components, aligning with referenced ASTM and related standards for durability and corrosion resistance.
  • Provides for compatibility with extreme marine operational conditions.

• Inspection, Testing, and Documentation

  • Describes hydrostatic, mechanical, and performance testing protocols.
  • Addresses certification requirements including documentation, technical manuals, and test reports.
  • Emphasizes safety, environmental, and health practices in pump use.

Applications

This standard is critical for:

• Marine Vessel Lubrication Systems
  CLPs specified in ASTM F2798-09(2023) are widely used in marine vessels where leak-free operation and oil integrity are essential for machinery reliability.

• Naval and Commercial Shipping
  The standard supports applications in both naval and commercial fleets. It is frequently invoked in procurement specifications for new builds and retrofits where high reliability and compliance with classification society requirements are crucial.

• Shipboard Engine and Machinery Lubrication
  Ensures pumps are built to maintain oil cleanliness, withstand ship motion up to 45º inclinations, and endure marine vibration and shock environments.

• Long-Term Service and Maintenance
  By mandating robust materials and rigorous testing, the standard contributes to reduced maintenance needs and improved lifecycle performance for ship operators.

Related Standards

Several important standards are referenced within ASTM F2798-09(2023), ensuring harmonization and broad industry compliance:

• ASTM F1510: Rotary Positive Displacement Pumps, Ships Use
• API Standard 676: Positive Displacement Pumps-Rotary
• ASME/ANSI B16.5: Pipe Flanges and Flanged Fittings
• MIL-STD-167-1: Mechanical Vibrations of Shipboard Equipment
• MIL-S-901: Shock Tests for High Impact Shipboard Machinery
• Various ASTM material standards: Covering iron, steel, bronze, copper, and other alloys required for pump and motor components.

Practical Value

Complying with ASTM F2798-09(2023) ensures marine lube oil pumps:

• Deliver leak-free, reliable operation, enhancing ship safety and environmental protection.
• Meet classification and procurement requirements for military and commercial applications.
• Remain maintainable and testable through clear documentation and standardized inspection criteria.

By adopting this standard, marine equipment manufacturers and ship operators benefit from consistent quality, interoperability, and regulatory compliance in shipboard lubrication system components.
