In which U.S. industries is the use of vacuum pumps large and growing?

Good day, Berniel!

I hope to pull out another unanswered question here.

In trying to look for industries where vacuum pumps were used, I
searched on the net for websites with mentions of vacuum pumps and
derived the uses from what’s mentioned on the pages. The pages
sometimes say what the pumps are used for or where they are used. I
looked at the sites more highly ranked by Google. These are guesses
since I could find no market report on vacuum pumps, nor any mention
of one, but I suppose the search hits in Google serve just as well:

Here are some of the industries I saw that use vacuum pumps, and the
sites I found that gave me the ideas:

- Air sampling for nuclear studies
Special purpose Lab vacuum pump by Atlantic Nuclear Corp.

- Automotive and light refrigeration
Digital Quill MVPro.com store for vacuum pumps
http://mvpro.com/mall/vacuum_pump.asp

- Pumping of acid vapors and corrosive gasses out of laboratories and
factories
Welch Vacuum Thomas
http://www.welchvacuum.com/products/lab/dry.html
http://www.welchvacuum.com/products/lab/high.html

Based on the above links, I’m sure vacuum pumps are most applied in
industries of chemical manufacture were air pollution risk is high
(lots of noxious fumes), as well as those where there is heavy
chemical usage (such as plastic or paint factories).

- Here are a couple of pages that show vacuum pumps are used in the
cow-milking industry:

- And one utterly unusual use for vacuum pumps is penis enlargement
(that’s gotta hurt if you ask me) and other sexual gratification uses:

Here’s good general FAQ on vacuum pumps by Busch UK ltd. 
http://www.busch.co.uk/faqs.htm

Google search strings:
vacuum pump application
vacuum pump industry statistics
vacuum pump (usage) purpose
united states vacuum pump uses

I got these since they are the most mentioned areas for vacuum pumps.
If I find more, I will post them in clarifications. Do look up what
solutionpro_ga posted below in the comments as well.

Have a good day!

Given what he had to go on, he apparently used a very good strategy to
present an answer.
