    Time to Say Goodbye to my RD-30

    Yep, you heard it right, I'm moving on from the RD-30... I think I was the first person to use this pump (2 years ago) and it has served me well. It is kind of funny how just now everyone is getting them. I've decided the new build (Beast 3) will not use the Iwaki. Max head will only be .6M less... It will make for a much cleaner install, be much quieter too. I haven't been excited about the new rig at all lately (been modding my car though ) but now with this new discovery of mine (probably not to all you guys) it has rejuvenated my enthusiasm for the project once again. Anyway, to all of you that are getting your RD's you will be VERY happy with them, they are amazing pumps. I will NOT be getting rid of mine so don't ask, these pumps are keepers!

    Welcome to the club.

    When running them in series the second pump tends to make more noise than the first one. I haven't found any good solution to this problem yet, I'm currently undervolting them. In a couple of weeks when I've had my last exam and all the parts have arrived I'm gonna try to find a better solution. I thought I'd try to enlargen the channels, put a T-line + fillport between them, place blocks between them, run them in parallell and use a larger ID hose between them. Hopefully one of these things will solve the problem! Any other suggestions on what to do to silence the second pump?

    I wish I'd bought Radiicals top instead, they have larger channels and there's a delrin version which looks great! The problem is that you have to buy them from australia which means expensive shipping.

    If you put them in parallel youll have the same combined head as 1 pump... so no real advantage over 1 pump but double the heatdump.

    2x Vs. 1 pump ? I don't get it. just get a bigger pump if you want more head.

    bigger pump = significantly greater heatdump and noise and size and so on (usually, at least for our uses)

    @andersson: Keep us updated on that! I really haven't found a solution to the problem too (that one pumpe is louder), strangely on my tests it's always the first pump that makes more noise...

    2 pumps parallel might work with these pumps, I do yet have to try it out. Maybe the head is good enough to provide more flow with a not too restrictive loop.

    ??? it may be by the time the water gets to the other pump,the flow is restricted putting more pressure on the second pump which has to work that bit harder.???

    parallel: same max head, double max flow.

    series: same max flow, double max head.

    I was a bit peeved when i read above that dual DDCs produce a 'noise',what about two DDC+s with the plexitop tanks?Ive read it's quieter than the reg.plexitop...and mine is quiet enough,will that have the same noise problem?

    EDIT:Its ok,just read Creidikis post,i was thinking in terms of series,not parallell.

    I'm always confused about this series and parallel thing. Tell me if I am wrong:

    Series: Assuming its only two pumps and some tubing. Pumps in series is when the outlet of one pump is connected to the inlet of another pump.

    Parallel: Again assuming its only two pumps and some tubing. The two pump's outlets are joined by a "Y" merging into a single tubing.

    yup... if you just think of the meaning of the words, it kind of makes sense

    Would 2 x Laing DDC-Pump 12V Ultra in series perform as well as 2 x AquaXtreme 50Z in series or 1 x Iwaki MD20RLZ?

    Appreciate advise from you guys, the experts.

    Also anyone knows what is the difference between this 2? Is it only the head and the pump remains the same?
