I was looking at a replacement regulator for my vacuum pump as ROR commented it looked like it had already been repaired, and at the dairy supply places they are $3-500. . . am I looking at the wrong thing, or am I going to have to invest that much in a regulator alone? Thanks Heather

We just bought a new one for our vacuum pump I think it was $10 for the regulator and gauge combo. We bought it at harbor freight but I dont see the one we bought on their website www.harborfreight.com maybe you can find it on there.
That thing you showed looks like a Vacuum gauge. The link you posted is a regulator, but I think those are for BIGGER operations. If you notice the HP is 3.5 - 10 that is a much bigger set up than what you would need for a single cow milking system. Your Vacuum pump HP will probably be no bigger than 1 HP. The one at Parts Department would work for you. You can also get a Vacuum gauge at Parts Department.

The gauge is on the bottom of the picture, but it is the thing above I need to replace. The vacuum control I guess it is called. I haven't found anything that looks remotely like it - what is it I need you smart people!? Heather
I think that is why the regulator is so big. Like I said before (or at least I think I've said it before) the more cows you milk the more HP you need (b/c you are running more milking machines on the 1 vacuum pump). If you are just using a small vacuum pump and 1 or even 2 machines you can use the regulator from Parts Department. You don't need that big $400.00 one. It's TOO big for you!!
Did you notice the one on Hamby's said "For cow and goat Milking Systems 3.5 to 10 HP" ? The HP is your Vacuum. If I remember right you won't be using that big a pump

I'll have to check my pump as it might be 3HP - it might just with the size opening and the size it is (80lbs minimum). So it may very well be too big, although I could certainly adapt it to work with my cow (overkill), it may be that I am forced to buy a more expensive "vacuum control" or find a smaller pump? The problem is the pump is at the in laws and I never get over there, but I"ll have to pick it up so I can look at it and answer all my own questions! Thanks dairymaid Heather

I found a rebuilt regulator that has the 2 inch opening and if I can use the sentinel brand it would be $140. I do notice that the smaller ones have smaller openings - maybe I can get some info off the regulator I have sitting on my counter *G* Heather
I'm putting together a vacuum pump and in the process discovered that regulators for these pumps are not what I expected. I've done some work on industrial equipment and expected these regulators to be the same, they're not. Instead of having a tank with relatively high vacuum and a regulator that delivers constant vacuum to the milking machine (vacuum regulator below), these are usually a valve that bleeds off excess vacuum to keep the vacuum from getting higher than the set point (vacuum breaker below). Some of them don't even do that and merely have an adjustable screw without a spring that bleeds off part of what your pump is producing. I'm sure if you were trying to milk many cows at once, the price of a real regulator would be cost effective. For one cow, it's tougher to justify.
