Fuel Oil Separator
A fuel oil separator spins raw bunkered fuel at several thousand rpm to throw water and abrasive catalyst fines out before the oil reaches an injector, and a unit running with the wrong gravity disc for that fuel's density will pass the contamination through instead of removing it.

Fuel Oil Purifier
Fuel Oil Purifier
A fuel oil purifier is a separator set up in three-phase mode for heavy fuel or distillate service, sized around the daily consumption of the engines it feeds and normally run in a duty and standby pair, since a stopped purifier quickly limits the fuel available for combustion.

Separator/Purifier
Separator/Purifier
A marine separator is a disc-stack centrifuge that spins fuel or lubricating oil at several thousand rpm to strip out water and solids. Whether it runs as a purifier, with three outlets for oil, water and sludge, or as a clarifier with no water outlet, depends on the gravity disc fitted, not on the machine itself.
375 models
Lube Oil Separator
Lube Oil Separator
A lube oil separator processes circulating system oil that is already relatively clean compared with heavy fuel, so its job is less about removing gross contamination and more about continuously stripping the trace water and fine particulate a fuel separator would never see in the same concentration.
211 models
Bilge Water Separator
Bilge Water Separator
A bilge water separator processes bilge water collected from the engine room before overboard discharge, separating free oil by gravity and coalescing stages and monitoring the effluent continuously, unlike a fuel or lube oil purifier which centrifuges a continuous, oil-rich stream instead.
170 models
Sludge Separator
Sludge Separator
A sludge separator is not a purifier doing double duty; it is a dedicated centrifuge fed by the sludge tank itself, concentrating the oily residue that purifiers and clarifiers already discarded so that as little as possible has to be landed or incinerated.
131 models
Lube Oil Purifier
Lube Oil Purifier
A lube oil purifier removes water and solid contaminants from circulating engine oil by centrifugal force, running continuously on a bypass or full-flow line, which is what separates its duty from a fuel purifier sized to condition a batch before combustion.

Knowledge

What a Separators & Purifiers engineer checks first.

The term separator or purifier on a ship's machinery list covers the same physical machine used in two different modes. Fitted with a gravity disc and set up for three-phase separation, it works as a purifier, discharging oil, water and sludge from separate outlets. Fitted without the gravity disc and configured for two-phase separation, the identical bowl works as a clarifier, removing only solids and passing oil and any residual water through together. Most engine rooms carry two or three units of the same frame size and swap duty between…

Would you like to know more?

One request. A person answers within 24 hours on working days.

Tell us the manufacturer, the model and what you need — a part, a service call, a second opinion. Our desk asks the right suppliers from a network of over 114,000 companies and comes back with a quote or a sourcing plan, not a search page.

Frequently asked

Three things people ask first.

Is Separators & Purifiers data free?

Yes. Every model page, every guide and every datasheet in this category is readable without an account. An account adds saved searches and requests, nothing is taken away.

My model is missing — what now?

Send us the nameplate. We identify it by hand, add it to the library, and if you need a part or a service, the request is already on our desk.

Can you source a Separators & Purifiers part?

Yes. Tell us the manufacturer, the model and what you need — our desk asks the right suppliers from a network of over 114,000 companies and comes back with a quote or a sourcing plan.
