They are a work-horse of a pump and at that price can't be beat;
their tolerance for abuse is exceptional as well. I'd only worry a
little about flat surfaces and the novice experiencing implosion
possibilities. I've imploded some glassware with those in my youth...
Thanks again for all the good info!
Yes, that's a 1402. I got it used for $300. There are a lot ofthem
available on the used market. I took it apart, cleaned it up,added
new oil and it runs like a champ. The only problem with it(besides
being really heavy) was that the original 1/2 HP motor hadproblems
getting it started. So I upgraded it to a 3/4HP motor with aheavy
start winding. It is overkill as far as volume flow is concerned,but
the larger oil capacity and overall design makes it less sensitiveto
contaminants than HVAC pumps. You really do need the high vacuumI
andlabsdo you really need that much of a pump? I've 8 of them in my
andproperly plumbed up they can draw a very serious vacuum...
