Does any one know what the lift
height of a March pump. How many feet
can it move fluid upward before it gives out? :?:

a google search says 210 gpm with a max head of 160". But it also says they make many different pumps so we would need more info for a more exact answer.

The ones from morebeer state:
"This pump has a maximum flow of 7.2 gpm with a maximum head of 12 feet."

Mine came from there, and I can tell you that I am pumping higher than 4.3 feet with no problems at all. I'm betting the 12 feet is accurate.

Simple rule of thumb for pumps. As head height increases, flow rate decreases. If you have any problems with head height, sometimes you can fix it by putting in a simple check valve downstream of the pump. Just make sure you don't put it in backward.
Another tactic is to put two pumps in series. This is often less expensive than buying a larger pump.

The reason that I ask is that with the pump that I have
which I got off of ebay. I have trouble getting it to pump wort
through my herms system. My HLT that hold the
heat exchange sits 22" above my mash tun
and the pump is below that. My last brew i just gave up :evil:
and moved the mash tun to a burner to adjust my temps.
Then used the pump to keep from scorching it worked great
no problem priming or flow rate. Any idears maybe a weak
or defective pump head?
It's seams that all March 809 pumps are not the same
the ones on ebay claim specs lower then the ones
on the More beer site. :shock:

Having seen your pump, I believe its spinning slower than mine. My morebeer pumps are much louder than yours. Morebeer does claim they had theirs specifically built for them. I know its not help, but I think motor speed could be your issue.

If the pump recirculates your mash okay, maybe you should try putting your tun at the same level as your HLT? Seems to me that would work. Also I have known of an instance where someone had trouble with their pump. It turned out they had it hooked up backward. I know it's simple, but worht double checking anyway. Just in case.

I check and it is going in the correct
direction. I ordered a pump head thinking that
maybe there something wrong with it. Then I
read yeastmeister post, I hate it when he's
probably right :cry: . I cancelled the pump head
and just ordered a new pump :cry: . I can
now move my HLT to the same level as
the mash tun and boil pot. And use the old pump to recurculate
hot water and cold water to chill with.

Some one make me feel better about my purchase
that doesnt work for more beer :P

Your old pump would make one hell of a beer shooter. Who needs funnels and tubes when you have an electric pump! :)
