Common Questions
Will it work for stabilizing wood in a vacumm chamber?
I use it for that because I am at 1700+ ft elevation and pull 27 Hg on my gauge.
Where can I get the oil for this?
It has 250ml of oil.
Will the pump pressurize to test for leaks as well as pull the vacuum?
It's not meant to pull negative pressure by pulling air out of a space, it will not push air into a space, and even trying to do so will break the item or cause damage.
I put the one away because I didn't want to use it anymore, but I found out that I bought a r10a instead.
I had a similar problem, I found a solution at a refrigeration supply.
I need a valve at the 14" fitting to prevent oil back flow after a pump shutdown. Anyone know of a link to one that would work?
It is hard to give you a clear answer because you don't have any specific information as to what you are applying this pump to.
