Seals - Pumps, Valves, Piping and Fittings

Marine seals provide leak-tight separation and protection in pumps, valves, piping systems, flanges and rotating equipment. Common types include mechanical seals, O-rings, gaskets, packing, lip seals and expansion-joint seals, selected according to fluid, pressure, temperature and shaft or flange dimensions.

ProShipWorks provides end-to-end support to source and supply Seals for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval

Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.

Applicable Standards & Certification Applicable standards depend on seal type and service. Common references include EN 12756 and ISO 3069 for mechanical seals, ISO 3601 for O-rings, EN 1514 for flange gaskets, EN 12560 for industrial flange gaskets, and API 682 for selected process-pump mechanical seals.
Class Approval Marine seals may be accepted as part of class-approved pumps, valves or piping assemblies. Where required, documentation may involve DNV, ABS, Lloyd's Register, Bureau Veritas or ClassNK approval; approval is product- and application-specific and is not universal for all seals.

Installation, Maintenance & Safety Information

Installation Notes Verify seal type, dimensions, shaft size, flange rating, fluid compatibility, pressure and temperature before installation. Clean mating surfaces, inspect shafts and bores, lubricate elastomers with a compatible medium, and install without twisting, cuts or contamination. Follow the equipment manufacturer's assembly instructions.
Maintenance Tips Inspect for leakage, wear, hardening, extrusion, corrosion and loss of compression during planned maintenance. Monitor pump seal leakage and operating temperature. Replace damaged seals and renew gaskets when joints are opened unless the manufacturer permits reuse.
Safety Notes Isolate, depressurize, drain and cool the system before removing a seal. Apply lockout/tagout and verify zero energy. Use seals compatible with the fluid and temperature, especially for fuel, chemicals and high-pressure systems. Wear appropriate gloves, eye protection and respiratory protection where required.
