Lapierre vaccum operated sap pumps

[Seguin Sugarbush]

Does anyone out there use these pumps and with what success?Here is my scenario.My next tubing installation flows away from the sugarhouse and i will have to setup my vaccum pump on a gas engine 3100 feet at the other end of the lot.I have a gradual 35 foot elevation for the first 1900 feet then it runs downgrade about 20 feet the rest of the way to the sugarhouse.I will have 2000 taps at that location on a wet dry system and planning on hooking up a honda 9hp on a 78 delaval head.Looking for input,

The pump will do it. It will require an additional 10 CFM to operate the pump above and beyond what your system will take. Also make sure that you can drain the pump totally or have a heated/insulated location for it.

I would put a vac pump at the sugar house and run 3000' of dry line from the sugar house to the end of the lot. Save your self a lot of time, labor, and money.

Lets say that you design the entire system to drain to the lowest point using 1 1/2" mainline. Then run the vacuum to the middle of the system with a 4" stand pipe about 10' high so sap cant climb the pipe. That will act like a dry line and all the trees will be under vacuum and the sap will run to the collection tank??????

My problem with running dry line from camp is that my gen(40kw) set is maxed out which I use to do everything else.I allready have the vac pump head which will put out plenty of cfm's.My worries were with the efficacy and reliability of the sap pump.Or I just put a 2000 gal tank and pump at the end of the day.
