Two pumps, two res, one loop. Will it work? - Page 3

post #21 of 23
Thread Starter 
Ok, how about having 2 pumps available and running them with either both on or 1off, 1 on.
Using a top like this:

Hooked into this res: http://www.sidewindercomputers.com/ekekspreac.html

This way they're running in serial not parallel though, right? So either on or off one shouldn't impede the flow of the other but with both on it's not exactly a strong boost. Am I right?

@ Veltri, how do you run them in Paralell? With a V-coupler to connect the tube out from both pumps?

That double top looks really cool. Maybe you could review it. My observations of it align with yours: series. Having one pump off won't matter much. It will introduce a slight amount of restriction but since the impeller is magnet driven and on a ceramic bearing, the restriction will be low.

You understand parallel perfectly. The only thing I would add is that 7/16" tubing should not be used after the Y junction. Also, a flow meter should be present between both pumps and the Y as failure of one pump will mean catastrophic failure of the loop. Of course, your components will be fine thanks to OHP. Something to consider. Also, this setup is most appropriate on less restrictive loops as the two pumps are already competing with one another. However, this setup will fvcking fly! 655s produce 11 ft of head alone (source needed, I know), paralleling will more or less double that. If you are working with all D-tek blocks - very restrictive - for instance, series is a more sensible choice. I can't really articulate how fast that water will be moving. We're talking like 110V pond pump fast. I will be experimenting with the setup in conjunction with my chiller when it's ready. I'll have a log.

Not sure why you wan't to 2 res setup for the same loop, I run mine like this with a EK type res, but you could adapt to just about any type res with a little imagination and the right fittings such as the BP D-Plug I use here.


Here's a couple ways of doing it,











Nice neat, clean and usable setup providing extra flow and redundancy.

Looks nice! I have the same idea, but I am going to use 2 D5.
