Does any one run one for pulling vacuum? Opinions? Experiences? I see Sugar bush supplies sells a gas and eclectic version. I havent been able to find much information on them.

I have not pulled and vacuum with it I have only push sap with it. I have it hooked up to my releaser tank. I have put my hand over the drain and does produce strong vacuum. Mine is hooked up to 5.5 hp Honda at vary little over idle I use 2 1/2 gallons of gas every 24 hours. I think it would definitely out perform the 2 diaphragm guzzler. I would try it but it’s the heart of my operation right now. And they are really easy to work on.Quote:

Mine ran for 5 days straight and my releaser would release every 7 minutes and it would take less than 30 seconds or so to to get the sap out of the releaser tank so to would be 6 1/2 minutes or so of dry running.
I have been running a Hypro D252 for almost 20 years now. Works great! I have seen almost 26 inches on the vacuum gauge. I have had diaphragms last 5 years but now i replace them at the beginning of the season so I don't have to worry about them. I disassemble the pump when I buy it, clean out the oil and run vegetable oil just to be safe. I will be adding one to a 300 tap sugar bush for the 2021 season.
Which hypro pump are you guys talking about? I'm intrigued.
Yes I would like to know exactly which D252 model. On ebay there seems to be different types of D252 models. Has anyone run one of these off of an electric motor?Quote:

I run a D70. 19.5 gpm
How many taps do you have on that D70?
