Shurflo Pump Question

[nekmaple]

I see a lot of you are using the shurflo pump and I'm interested IV got about 300 feet of 1/2 main with 60 taps on gravity,runs real good but I want more lol. So what does everybody recommend I see a lot use a 2088 model is that the best and we're is the cheapest place to get them?

I find it imperative to have sap trickle into the pump during slow periods, slow meaning when sap will sit around on gravity or not even flow.
Slow periods is when the pump is really important. I suck sap from my collection tank (just a bit) and just return it to the collection tank(full cycle). Doing this gives more vacuum to the lines in the bush. Also keeps the pump drinking fluid/air at all times. Again, only when sap is not flowing good on its own. A good flow day I do not suck from my collection barrel.

I use a manifold on my pump and it works great, you do need to babysit it though during slow times to fine tune it. If sap is running good, just plug and play.

Hope that makes sense.

Great idea! To suck "just a bit" are you putting a dedicated lateral into the tank? Then do you just plug it up when it starts moving? I'm going to try this, too. I wonder if something like this would work in line to allow tank in-flow at low pressure?

CampHamp. I will be using a shurflo this year for first time. I have a thermostat like yours and am wondering what you have your settings programmed to.

This is last years manifold, but same idea to pull sap from collection barrel if needed. Manifold-3.jpg

Three taps needed minimum.

First black tap closest to mainline (black poly), that allows you to shut off line to the bush.

The second black tap is right in front of the intake of the pump. Close off that tap and open both other taps you are on gravity, no pump needed.

The fun part now.......with the bush tap open and the intake tap open, ever so slightly, just a smidge, open the gravity line tap,,,,It will suck from your collection barrel, just allow a tiny tiny bit of sap to enter from collection barrel. This will make the pump happy and pull stronger in the mainline. Fine tune the handle for the perfect sap/air ratio.

There is no reason to grab sap from collection barrel is sap is running good. I only suck sap from collection barrel to avoid pump from long dry running times,, slow sap times.

Hope that makes sense.

I use a 4048. Not the cheapest route, but it's in its 2nd season with no issues. I have a write up off the parts and pieces with costs on my website. I am curious what everyone else uses. I just bought a second one from Amazon with the strainer for $160 ish.

I use three 4008. I get mine from a close friend who owns a RV store right local to me. I think retail on them is somewhere around $116.00 plus the filter Wich I think is about $12.00.

CampHamp. I will be using a shurflo this year for first time. I have a thermostat like yours and am wondering what you have your settings programmed to.

I start up at 1C and stop at -2C.

I let the sap freeze before stopping the pump so that no sap flows beyond the screen, otherwise it will become ice and potentially hurt the pump when switched on. Also, running the pump into the freeze leaves some vacuum locked in the tubing and might help get things started the next day before the ice fully clears. Some folks keep a light in their pump-box and don't need to worry about over-night ice.

To set the turn ON temp, just press SET and +/-. "Hysteresis" is the change in temperature allowed before shutting OFF, so in my case it is 3 degrees -- to set this one you hold the SET until you see P0 then hit + for P1, then hit SET and +/-.

Yes - got it. I have free ports on my mainline to accept a 5/16 right near my tank. It may happen this coming week...

Any difference in vac between 4008 and 4048?

What do you guys use for connecting the pump to a 1/2in mainline? I use a 1/2 barb to threaded 1/2in but I can't get a good seal on the barb. I tried heating the pipe and using two hose clamps. I see there is a very slight leak right on the barb. I'd like to fix this.
