<DIV>I purchased my Gast pump from the Surplus Center in Nebraska a few years
back and I do not remember what I paid but it was a lot less then $400
dollars.</DIV>
<DIV> </DIV>
<DIV>I would give the Surplus Center a call and ask them if they have the pump.

<DIV>How satisfactory are the vacuum devices that run off an air
compressor? I'm told they are very loud. Is a vacuum pump a better
direction to go? <SPAN style="COLOR: rgb(192,0,0)">They are loud and I
just don't feel like their in the same league as a vacuum pump.</SPAN><BR
style="COLOR: rgb(192,0,0)"><BR>How reliable are used vacuum pumps? I
see them on eBay for about $45 or so. <SPAN
style="COLOR: rgb(192,0,0)">Used pumps can be as good but they are a
gamble. What were the pumps used for prior and how well were they
cleaned after use? There are many variables to consider. They're
not bad but not always good either.<BR></SPAN></DIV>
<DIV><SPAN style="COLOR: rgb(192,0,0)"></SPAN><BR>Are the pumps used by HVAC
technicians to draw the air out of air conditioning systems
satisfactory? <SPAN style="COLOR: rgb(192,0,0)">Depending on the size,
possibly. Like the used pumps there are a lot of variables.</SPAN></DIV>
<DIV><BR><SPAN style="COLOR: rgb(192,0,0)"></SPAN></DIV>
<DIV><SPAN style="COLOR: rgb(192,0,0)">When it comes to pumps, Gast's model
0523 is the pump that is in the catalogs for $440. It's the best of the
best. There are parts available if the user does have problems. If
you do a search on ebay for Gast 0523 Pump you'll find some options, again a
lot of variables. IF you order one, expect shipping in the $30 to $40
range alone. There is another pump available that has been getting some
good reviews and is half the price and is a "New" pump so there are no
questionable variables about useage. Stubby Lathe USA carries it as well
as some adaptors (the adaptors are made of delrin and will need to be turned
down smaller to fit our lathes). Here's a link to them.

<DIV><SPAN style="COLOR: rgb(192,0,0)">Also there are many articles on Vacuums
around. Some are overly complicated, in my opinion. It doesn't
need to be. Keep it simple.</SPAN></DIV>
<DIV><BR><SPAN style="COLOR: rgb(192,0,0)"></SPAN></DIV>
<DIV><SPAN style="COLOR: rgb(192,0,0)">This is just my 2 cents on the
subject.</SPAN></DIV>
