<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">good afternoon. Here at UofM/LNF we've had several different liquid ring systems over the years. One was original to the lab/building (1984 vintage) and a second that was installed as part
of the lab expansion back in 2007. Both systems have been replaced (about 5 years ago) with a pair of Quincy QSV-345 vacuum pumps. We have a large holding tank (~600 gallon) in between the vacuum pumps and the delivery system. These two Quincy pumps alternate
every week, and to date, have performed flawlessly with just routine maintenance. <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">At one point, while we were switching from the old vacuum pumps to the new ones (about 6 weeks), we used a couple of Ebara A70's to provide the vacuum. That was OK short term, but not something
that was workable long term.<o:p></o:p></span></p>
