Gast 0823 for 300 taps

[idefix69]

Hi Still looking for a pump to put on my 300 taps

What you guys think about the gast 0823...

Looks good to me but really not an expert

Thank

I've used almost the same pump for 4 years now. We have a pair of the 1023 pumps.
We started with only one on about 650 - 700 taps and when the system was reallllllllll reallllllll tight, we got
very close to 21". We run 3 releasers, no ladders, 900 feet from the pump(s) to the first releaser and then Y split
another 400' and 600' to the second and third releasers. I was hoping to inrease the vac a few inches by adding
a second pump the second year but that was a big disappointment. It could be I was not maintaining the systrem
as tight the second year. My impression is that in real world use they do not get the linear vac that the charts represent.
I think that over 21" will be nearly impossible to get in a bush where the trees give us a certain amount of wood gas.

In any case, we love them. Nearly mainenance free, oil free.

I think you should be very happy with the 0823. We got ours on Ebay for about $ 150 - 200 each.

The biggest problem I see with the Gast 0823 is the lack of CFM that it is capable of. Where they are rated for 26.5"/hg of vacuum, they only are rated for 8 cfm. Don't get me wrong, I run Gast pumps on my sugarbushes (1550's), and have had good luck with them. Even lifting sap 10 feet, still have good vacuum at the end of a (verrrrry) flat, 400' mainline.
