Shurflo 2088 Vac system?
I’ve gotten a Shurflo 2088 to hook up to my 100 plus taps as a replacement to a diaphragm pump that finally self districted. Now I know the Shurflo is a low CFM pump, but when attached to a vacuum gauge, with no tubing attached, and plugged at the intake, it only pulls about 7”hg. Does this sound right?
That's about right when running dry. The vacuum will increase when you start pumping liquid. Try recirculating some water, using 10' of 3/16" tubing on the inlet side. Tee in the gauge. You should see vacuum a lot higher, maybe 20" or higher.

Thanks for the advice. Is there a way to make a sap recirculator to keep the diaphragm wet during the season?
My pump pulls from a manifold with 6 lines attached to it.
I have a 7th line with a needle valve that allows me to pull from the collection barrel.
I can se the valve to only draw a little from the barrel but keep the diaphragm wet and pulling higher vac.
I use this when the sap flow is slow. With good days, it is not necessary.

I know I'm in the wrong thread but I have a 1/3 hp pump that I have tested to pump sap up to my sugar shack it will do about 20 gals every 3 minutes. It's over 30 ' of rise. I texted with 3/4 hose would it be beneficial to run an fixed line of 5/16 to pump through since I run 3/16 or would the pump work to hard through a smaller diameter
2024- 500 taps on vac
100 on gravity

Your pump will work harder through the 5/16. I'd stay with 3/4 for less line friction.
Remember to keep on ticking while the sap is dripping.
2016- 50 buckets. Made 4 gallons.
2022- 3750 taps + Smartrek! Made 1300 gallons.
2023- 3750 taps after removing a pump house and connected two woods. Made 800 gallons.
Tee a small line into the mainline with an adjustable valve on the suction side of the pump. Run the small line into the bottom of the storage tank. Adjust the valve so that the pump pulls a tiny amount of sap out of the tank, just enough to keep the diaphragm wet at all times.Originally Posted by Mapleblood

I have to get better at using my recirc. line. I'll have like 10' of sap backed up in the mainline coming in with nothing moving. I've thought the pump was blocked, then all of a sudden, it will take in all the sap in a huge slug. Then it all starts over again. I can't quite figure it out. I'm hesitant to put a recirc. line on my remote setups because of all the adjusting needed. How often are you all adjusting the needle valve?

Around 300 taps on tubing, 25+ on buckets if I put them out

What pump is that?
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
Usually I adjust it at the beginning and that’s it. Sometimes I will play with it again but usually it is not necessary.
