Marine equipment operates in environments exposed to saltwater, pressure variation, continuous vibration, temperature fluctuations, and mechanical stress. Sealing systems must maintain reliable performance under constant exposure to moisture, corrosive media, and demanding operating conditions.
Applications include ship systems, offshore equipment, hydraulic steering systems, deck machinery, pumps, compressors, valves, and marine auxiliary equipment requiring stable sealing performance over extended service periods.
Pulim supports marine OEMs, shipyards, and maintenance providers with sealing solutions selected according to operating conditions, media exposure, and service life requirements.
Marine sealing systems are subject to combined environmental and operational stress. Typical challenges include:
These factors require durable materials, application-specific seal designs, and reliable manufacturing processes to ensure consistent performance.
Pulim evaluates marine applications based on operating environment, pressure levels, motion profile, media compatibility, and service interval requirements. Materials such as PU, HPU, PTFE, filled PTFE, NBR, FKM, and engineering thermoplastics are selected according to corrosion resistance, wear characteristics, and sealing performance targets.
Seal profiles are adapted to maintain performance under both static and dynamic conditions. Molded and CNC-machined production methods support standard products, custom geometries, retrofit projects, and new-build applications.
Engineering evaluation is completed prior to production to confirm material suitability and manufacturing feasibility.
Material options include PU systems, PTFE and filled PTFE, NBR, FKM, and engineering plastics selected according to environmental and operational requirements.
Pulim applies testing and production controls based on application requirements. Depending on project scope, evaluation may include:
Production processes are controlled to support reliability and repeatability across marine applications.
Marine applications often require non-standard dimensions, durable materials, long service life, and responsive replacement support. Pulim supports these requirements through both molding and CNC machining capability.
CNC machining enables production of custom sealing components, large-diameter parts, and urgent maintenance requirements without tooling dependency. Molding supports stable supply for standardized production, while digital production systems help maintain consistency and process control.
