Thanks for all the help guys. It turned out to be a combination of things. Eric from Lappierre gave us advice over the phone, and with his help we discovered that there was some damaged stages in...

all the resets are fine, and still had the same problem when we went to concentrate today. Running out of ideas......

would it still be working at all if a reset was tripped?

I did just check the breakers in the machine, and all the screws on the breakers are tight, and the breakers weren't tripped, but the screws inside the outlet were not super tight, and the plug was...

And nothing else in the sugar house seems to be affected. The vac is working fine, which is the only other thing that has a big draw, and even when I turn that off, I still have the same problems...

Also, it is single phase. And it is not shutting itself off at all, it just doesn't want to bring up the pressure without us doing multiple on and off cycles.

All the connections on the machine itself seem to be tight. They used heat shrink stuff around most of them and I can't imagine they are loose under that, do you think? I didn't check the screws...

I think that it does seem to be something to do with electrical. When the problem with the pressure first started, we also had problems with the breaker for the RO overheating and tripping. It had...

I could really use some help here. We have a Lappierre turbo with 2 membranes which was working just fine until a couple days ago when we could only get the high pressure to about 100psi. Called...

this set up is actually 2 front cross flow type syrup pans and switching flow requires actually switching out the two front pans , by draining and unhooking and swapping them out, or paying the grand...

ordering an evaporator with 2 front cross flow style pans, and they have the option of adding extra plumbing so that the 2 pans can basically be reverse flow by switching valves. It adds about a...

Thanks bowhunter, that was very helpful. I see that they say that pressure does not effect the life of the membrane which is reassuring. And yes, we do have it cleaned and tested after each...

Sorry I took so long to write back and thank you bowhunter, but the sap has been running well here for the last week and I finally got a break. Your information has been helpful. I have actually...

thank you bowhunter, and yes there is both tables of data and curves. Here is a link to the manual. The info I was referring to starts on page 25 ...

we have a Lapierre turbo 600 and in the manual it gives all this technical info about how the sap temp affects the processing, and how warmer or colder sap will effect the life of the membrane, but...

And how would I know if I was flooding it? Or how would I know if it wasn't getting enough oil?

We are using vac pump oil mostly, and at about 20" of vac. I don't know how to adjust the flow of oil. Can you tell me how to do that. Thanks

Hoping someone can point me in the right direction. I have a airablo vac system, with a delaval electric vane pump setup with reclaimer and we keep having problems after it's been running for a few...

I took it to a friend of ours who works in a machine shop and is an engineer, and he thinks he can make a new shaft. He also said that the bearings are pretty bad which is why he thinks the shaft...

well the shaft did break off inside the drum. The Delaval guy said it had to be a fault in the metal. But he also said that pump has not been made for well over 10 years and we bought the system...

Just a quick clarification. I said at the beginning that it was an Airablo, cause that's what my owners manual said, but the pump itself is made by Delaval

I started a new thread, when I realized it was a different problem, but then I posted on the other thread to explain what I found. Sorry for any confusion.

Well, here's the thing, it looks like the keyway is short, but in talking to the Delaval guy today, this might be a bigger problem, not sure. It is difficult to tell on the diagram of the pump...

It is just a basic keyway, so I think you are right, I could have one made. We have a Delaval dealer in the area, so I am going to take it in to them and see what they suggest. I just wonder what...

Our vac pump quit producing vacumn and pumping oil at the end of the season, and we had thought the vanes had gotten stuck, but I just finally took it apart and the vanes are fine but the key that...
