Pump placement advice

Finally made up my mind and got all my watercooling equip. with the exception of the heatercore (on the way). What I need to know is this: will mounting the pump in any way other than base down hamper its function? My plan is to place the DD D4 (Laing?) on the front wall of the case (below the 3.5" bays) with the pump base against the front wall and the input facing down/output facing back of the case. Will this cause any problems or should I wiggle a way for the pump to sit flat on the bottom?
 
It won't matter, aquarium pumps aren't typically mounted the same we us watercoolers mount them, there's no standard way. They don't rely on gravity for anything, so orientation doesn't matter.
 
they rely on one thing: priming. They are generally not self-priming, and if enough bubbles are in the loop, the pump will stop working if not gravity-fed.
 
Of all the orientations you can use on these pumps, you chose the one that's definitely not recommended. These pumps produce practically ZERO suction, so with a downward facing inlet you're going to have a hell of a time getting the loop filled without grinding up the pump, and you might experience cavitation later.

Sorry, I should have specified that certain orientations are not practical for loop filling purposes, but would work otherwise.
thewhiteguy - almost all aquarium pumps the pull through undergravel filters are oriented in this way, how can it be so terrible?

Beucase they are submerged and therefore there is water pressure at the inlet. If you make it draw water up through a tube it's an entirely different matter.

If you only knew....I find the hard way to do just about everything. From what's been posted so far, it seems I can mount the pump on the side with the inlet facing up to alleviate the priming/suction problems of my original configuration. Thanks for the help everyone. This is exactly the kind of info I was looking for.

You're right, I was thinking of suberged pumps. I still fail to see how gravity matters though, since the only restrictions are friction-related in a closed loop.

It doesn't matter so much when the loop is bled, but filling it will be a bitch because whenever a little bit of air gets to the pump it will start cavitating/running dry.
 
i have run my Via Aqua 1300 in a similar orientation and it always worked fine. As long as the pump isn't at to high of a point in the system there should be enough gravity from the lines coming down to over come going up 3-4 inches.
 
As long as your fill point exceeds the hight of the pump, any orientation will be fine.What many people fail to realize is that pumps simply circulate water in a loop. As long as the pump is below the water level, it will prime and pump. Any amount of water a pump pushes out will displace the same amount of water to the inlet side. Reservior placement or fill/bleed line placement is more important than pump orientation

Let's talk a bit about that issue, as well. Per my previous post, I'm going to face the inlet up with the outlet running parallel (more or less) with the base of the case. Would it be a good idea to put a T-line in somewhere above the pump inlet so filling and bleeding will go a little smoother? (i.e. allowing the incoming water to gravity feed directly to the inlet)

a T-line should work.

My pump is placed upside down as well, havent tested it yet though :(
