Vacuum pump question Steve R. 03-06-2008

I have a chance to get an old, but serviceable medical vacuum pump, at a
very reasonable price. When I switched it, gave off a very offensive odour.
What is the best way to decontaminate the thing? I am thinking in terms of
lots of alcohol, but am open to suggestions.


Thanks in advance.

Steve R.

Depends what the odour is caused by. Try to find out what it has been
used for in the past. Ask the seller. The odour might be something
dangerous, but it might not. If it's something dangerous,
decontaminating it is a difficult job. If not, just change the oil.

Incidentally, the old belt-driven pumps are often much better made than
the modern direct-drive pumps, so they can be a really good deal.

Best wishes,

Chris

It's just a little portable direct drive unit. The manual suggests that
should be used for suctioning out newborn babies, and small surgical wounds.
I have no way of tracing the original user. It was donated to a local thrift
store, but probably came from out of town.

I decided to buy it anyway (under $20.00). It will have to live outside
until the smell is gone.

I would not use alcohol near any seals.

Can you close the inlet and let it pump vacuum for an hour?

Yeah, those drunken bastiches might fall off the dock and drown.
