Guzzler as a vacuum booster

[nas]

I have no experience with guzzlers, but I was wondering if one could be used within a vacuum system at the bottom of a sap ladder to help push the sap up the ladder and to boost the vacuum below the ladder?

Sure they could. What is your vacuum pump?

That's a neat idea. Please keep us updated on what you find. I have never thought of this but if it works I will be.

Which Guzzler pump would you be using? Single diaphragm pump should work OK. Dual diaphragm pump may work OK as long as there isn't much backpressure on the outlet side.

My situation now is that I have a 600' mainline that ends at about an 8' ladder. Below the ladder the main goes under a train track and then about 1000'. It is a fairly flat line and last year I seemed only be able to keep about 15 inches of vac at the end with about 24" at the releaser. I added a dry line to the main this year so I will wee how that goes, but may try the guzzler if I want more. If the guzzler doesn't work, I have a place I can use it in the future and will probably try the new CDL electric sap lifter.

So I installed the guzzler on Saturday, and we had good runs Saturday and Sunday and it really helped. I'm now seeing consistent 21-22" at the end of the mainline.
I should clarify that my main problem was that the ladder was not keeping up during the heavy flow times, so I only need to run the guzzler then. I actually installed it in a bypass around the ladder with a Tee just before the ladder and then teeing into the main above. That way when I shut off the pump, the sap doesn't have to flow through it, but can still go up the ladder. I also put valves on each side of the pump and quick couplings so that I can remove the pump while the system is under vacuum. I also close the valves when the pump isn't running.
I hope this makes sense...
