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.

Sounds like it got used and was not properly cleaned. What make/model is
it. Many of the portable units come apart and can be sterilized in an
autoclave. All of ours can be and they are various years. Depending on the
unit replacement parts are likely available. The Laerdal and DevilBiss
units we have can be stripped down. These units do not use oil usually,
they have nylon or similar rings and parts in the pumps.

it's more like a jar of jalapenos-
what you do today could burn your ass tomorrow!

Thanks!. The trap will come apart. At the moment it's plumped up with
surgical tubing. That will be disposed of. I'm sure that it's oil free. I
will check on the make. It's late at night here, and the pump is in the
trunk of the car, outside. I thought it might be useful for testing
automotive vacuum relays, and debubbleising stuff I do in the workshop. No
way will I throw it out!
