Do you happen to know if there is any centrifugal separator on the

Alfa Laval makes a cute little unit that will process about
170 liters/hour. Alfa sells it mounted on a cart with pump
and controls for use as a portable oil polishing unit. The
centrifuge is available by itself.

I would love to have one but the cost is a bit too high to
justify its use on a pleasure boat.

Btw., I once had
a Scania truck diesel engine which had a centrifuge for its
lubrication oil. Judging from the amount of gunk it separated out of
the oil, it worked very well.

A "spinner" that worked off the oil itself? Those things are
great. Have used them on several diesel generator sets and
they do an excellent job. A little trick to make them easier
to clean, line the bowl with a single layer of newspaper.

Interesting.

Yes, you're probably right, unless you could share it with others,
being a portable unit.
I was thinking of a small unit which could be permanently attached to
the fuel system and used either for polishing or for processing the
fuel when filling a day tank.

Yes, it used the oil pressure to spin the bowl, and you had to
manually clean the inside of the bowl. The newspaper trick would have
been great, but I did not think of it 25 years ago...
