Hmm looks a bit like these old milk separators.
We have one of these in my fathers old house, hand driven though.

A 30-inch Knelson Concentrator spins at 400 RPM · creating the effect of 60 times the forces of gravity. Not sure how long you could drive your old milk separator by hand at that speed or if it would be balanced well enough not to spray itself over a wide aria while you did it.LOL

I said it looked like, not that it compares.
