Water Pumps and RISE anyone got any info on this???

[sparks]

I have a BE cooler and it uses the rio 180 pump.
Well it works fine sitting in the bottom of the case.
Only about 6-7 inches under the cpu.
BUT I want to put the radiator and pump in the top of my tower case.
This would be about a 14 in rise for the water.
Can the Rio 180 do 14 inches?
Is there anywhere to go for info on this?

thank you for any help

p.s. does anyone have one of these? Did you get the fined sinc to go with it?

The number (14in) you are talking about is called pump head. A Rio180 will do it, but it won't pump @ 180gph. The more head you have on a pump the lower gph. You can get this info from the pump manufacturer, its usually a graph with gph on the vertical axis and head on the horizontal axis. I got my graph from the place where i bought my pump. Hope this helps...

Will the loss of flow also put undo strain on the pump shortening its life?
I just dropped this thing in last summer, I was trying to learn about water and peltiers and it worked great. I know its not a high volume pump, I did not need one BUT when I started to move it to the top of the case I noticed that the tubing would have to be lengthened about 2 feet and it got me to thinking why.

will try to find the rio site and see what they say
thanks again

Nope it won't shorten the pumps life, as long as you keep the pump within the specified head. As for strain, more head does strain the pump more but its designed for that, so running 2 pumps at 0 head and one at max. head, both will crap out around the sametime

Well I got the specs on the pump, finally.
max head 3 ft
0 ft 120 gpm
1 ft 87 gpm
2 ft 95 gpm

now how can they get more at 2 ft then at 1 ft?
maybe its because I can't read the damn pic they have on their web site. I looked again and it looks like
?5 well mabe b5 hell I can't tell so lets say 65.
still I won't need 3 feet

so here goes with the water on the 1.2.....weeeeee
well I will wait till sat to do the final install and test.

you could just get a larger pump, they aren't terribly expensive.

It'll be fine.

The biggest inhibitor to flowrate will be the diameter of the tubing. Although, the Rio 180 isn't designed for very large bore tubing. So there should be no significant bottlenecking in your proposed setup.
