Shurflo pump VS. other Brands of Diaphragm Pumps

[markct]

24v can run off two 12v batteries that's how its done in heavy equipment, two 12v batteries in series. They don't make 24v batteries other than for stuff like electric forklifts

just watch which 24v you are looking at. many aquatec RO pumps are 24v AC. those need the power supply that goes with them. the 24v DC pumps can go off a pair of 12v in series.

feet of lift seems to be a gray area. all different numbers on the pumps, but they all seem to pull up in the 20's when wet.

it would be nice if someone would post a picture of 1 of these with a vac gauge hooked up

Can the discharge on the shurflows be say a foot off the ground and then directed up 4 feet into a cage tote with a hose? Would this sacrifice any performance?

no, in fact, it helps quite a bit to have a head of liquid in the discharge line of the pump. i spent the day yestrday watching and re-engineering my setup. i put my aquatec 8800 on a short 100' 5/16 line in the yard with 12 taps on it to see if i can get the most out of it. doesnt sem to be a lot of info about these setups online yet.

with the discharge going directly down in the bucket, it drains empty. when the pump pulls sap, it pulls way harder than when its pulling on air in the suction line. with sap, it gets vac up in the 20's and stalls out when a big bubble gets to it. then it sits there trying to pull that air out with nothing moving until the vac in the line drops back to about 12". if the discharge line is dry, the pump cant resist the higher vac and some of the air in the discharge slips back in the suction line. but with a loop in the discharge to hold sap right at the pump outlet, it creates an air lock since theres no way the pump will allow that bit of liquid to get pulled backward through the pump head.

so now when the sap gets to the pump, the pump pulls and pulls until vac is up in the 20's and stalls on an air bubble. now the vac stays in the 20s, slowly dropping as the taps fill the line with sap, lowering the vac back down in the teens till the pump can beat the air bubble (which is much smaller thanks to the wet discharge line not allowing 3' of air back in the suction line) and it grabs the sap, sucking it back up to 22-25". this cycle goes on all day, holding much higher vac on average with the wet discharge

a recycle timer would save a whole lot of running time on the pump. thats todays project

this is the pump i have, it pulls 5.5 gpm and thats the most out of any diaghragm pump iv seen in this price range, its got 10" of vacuum unsealed in my living room, i have yet to test it in my sugarbush, I'm gonna have it hooked up to about 200 taps and as long as it helps move the sap along i will be happy!

if vacuum is effected by gpm this pump should do better then both 4008(3gpm) and 4048(4gpm).

will see!
