Check and see if there is a filter on the input side which will need
to be replaced. The more expensive units have a filter to prevent
foreign objects from getting into the pump and destroying the
precision parts. These filters (like an automotive fuel filter) tend
to trap odors and materials, whereas the metal parts of the pump
itself are unlikely to trap odors. For the same reason as the filter
was originally intended, you should avoid putting any liquid,
particularly solvent, into a vacuum pump, unless you have the entire
thing disassembled on a bench. These pumps are designed strictly for
air and gas use, not liquid or aerosol. If it's ex-medical, it was
probably used for suction or something, with the vacuum evacuating air
from a filter/trap unit, and the waste being sucked into the trap.

This one is for medical use, as in suction, and has a bottle for the sucked
up fluids. It's rated at 25 inches of Hg max.

I would get rid of it.
