Oily Water Separator Spare Parts Suppliers
Even the best separator system won’t last without proper upkeep. Like any equipment exposed to bilge water, marine oily water separator components wear down over time - filters clog, seals degrade, sensors drift out of calibration. Regular maintenance is essential for staying compliant with MARPOL regulations and avoiding discharge violations.
That’s why sourcing high-quality oil water separator spare parts is a top priority for engine room teams. From routine inspections to annual servicing, every stage depends on reliable parts that fit your specific system - and perform without compromise. Whether you're running a compact unit on a workboat or a multi-stage setup on a tanker, access to the right spares makes all the difference in uptime, crew workload, and regulatory peace of mind.
Common Spare Parts and Service Kits
Most oily water separators follow a predictable service cycle - and that means certain parts are always in demand. Ship operators typically stock a mix of consumables and critical components, either as standalone items or packaged in OWS maintenance kits.
Common bilge water separator spares include:
- Filter elements and coalescers - core to every stage of oil-water separation
- Gaskets and O-rings - replaced regularly to prevent leaks and pressure drops
- Float switches and sensors - for level detection, pressure, and oil content
- Solenoid valves and drain valves - often exposed to dirty fluid and wear
- Circuit boards, relays, and timers - for automated control panels
- Calibration kits - to ensure the oil content monitor stays within spec
Some OWS spare parts manufacturers also offer full annual service kits tailored to specific brands like Alfa Laval, Jowa or Marinfloc. These kits help simplify logistics and ensure compatibility during scheduled drydock or voyage repairs.
