Pumbing Reef Flow Dart

[caad3]

Hi all,

I was thinking about switching pumps on my 120 Reef ready aga tank to a reefflo dart. After reading some reviews, I was curious if MR members have had any experience with the pump. Also the plumping size states 2" for inflow and 1.5 for the outflow. My overflows are hardplumbed for 3/4" can I get reducers to fit my system? Also do you think it will impact the pumps performance.

I am currently running a p4 titanium pump and I love it. It is so quiet, but it does raise the temp of my tank 5 degrees.

Thanks, James

I wouldn't restrict the flow. It causes damage to the pump in the long run.

james I have the reef flow snapper, same size.
I have the input coming from my sump at 2"
the output leaves at 1.5" then enters a chiller at 1" and returns through 1.5"
I tried not to restrict the flow.

Crox, not being a "richard" but why would they produce a pump with a 1/5" outlet that would get damaged if it was restricted when just about the whole reefing world uses 1" drains and 3/4" returns? Seems like a bad plan to me, but I am just asking, not being confrontational.

Caad, if you have the stomach fro it, check out Latino's thread and see how we plumbed the reeflo into a ocean motion 4 way as well as a manifold to feed the rest of the tanks equipment. It can be done, but there are serious space restrictions when you configure reductions.

Good luck with it.

Running the Snapper on my 180 as well, 1.5" to a manifold to standard 3/4" returns. I spoke with the guys at Reeflow and they said reducing the output will not harm the pump; usually reduces energy use as well.

Using a Reeflo dart on my system. Pump instructions specifically state that you can throttle (i.e. restrict) the pump on the output side.

Centrifugal pumps will leak at the seals over time. I've changed 2 seals on two different Darts already. Funny though the 3rd one that I am using is fine for the past 18 months.

unless there is a circuit to regulate n reduce voltage to the pump, the restricted flow will increase pressure n is only a matter law of phyics that the seal will be compromise.

Jim,
You and John did a terrific job, especially with the space restrictions. John, told me that there was a lot of calculation, cutting and bending...with minmal space...anyway great job!
However, per caad3 thread, he mention that he is wanting to replace his return pump for a reeflo pump. If that is true, how would a Ocean Motion work. Even if it was possible, it would be too costly just to plumb a return pump to his sump. I believe the easiest way and cost effective to take the sump out drill a 2" hole and then plumb in the Reeflo Snapper.

you can reduce the outlet of the snapper
you cant reduce the inlet of the snapper

Jim,

I said in the long run you are going to encounter some problems if you restrict the flow (seal leak, etc.). I had a snapper and I restricted the output to a 1" and when I spoke with Chris (loismustdie) about the pump being loud he told me to change back to 1.5" and to not restrict the flow. Well I changed it and the pump was not noice any more.
