Sequence ReefFlow Dart

Thinking of getting a Sequence ReefFlow Dart as a return pump for a 180 gal. Anyone use one of these or know anyone who uses one?

i have a Dart for my closed loop system on my 180... works awesome!
but this is not the type of pump u want for a return pump these are meant for flow only applications.... it would be a waste of a pump being used on a sump return ....
on my sump return for my 180 i run a pan world 100px-x which does about 1200gph but has more head pressure .... ur dart will be underpowered and worked at the same time ....
get a pump meant for a sump return setup....
how many gph is ur overflow guna handle.... most overflows on a standard 180 can only do about 1000gph so stick with something around that rate
sequence also makes a pressure rated pump that would fit ur application just depends on what u want
just a lil FYI

Dart wouldn't be a waste as a return pump.......You don't need a pressure rated pump for sump return......The Dart will more than handle your needs, the question as Murph pointed out will your overflows handle what the Dart will push......The electrical consumption of the Dart is good as well.....It does not hurt the pump to valve it down as well if needed.....These pumps are designed for that and it causes the motor to downspin and with regards to that the more headpressure the less energy it will consume......

hmmm i get what ur sayin acrylic but i just thought that these were flow pumps cuz i know as soon as u start adding in smaller plumming and elbows this pumps output gets cut way down....
yeah its electrical consumption is good but my pan world only pulls 100w which is less than my dart and it does the job....
not to say that it wouldnt work but i know to run them optimally they require alot of water... they come with a 2" inlet and a 1.5" outlet when u downsize to fit a sump its guna cause it to overwork IMO and be a waste of a pump....
unless u have a super high flow mega sump lol that can do 3000gph if u do then go for it!

Nah.....your correct they do come with the 2" inlet, but downsizing the inlet doesn't affect the pump at all.....that info comes straight from manufacturer.........I don't understand why you need a pressure pump in this situation??? There is no pressure....as long as he doesn't downsize the lines till he gets to his destination. I run a HammerHead and I've put elbows to the thing and yes it does cut down some but that is more than enough pump for the sytem.......yes elbows out the butt and 3/4" pipe would be insane to do.....even 1" IMO would be a no no.......
Again putting backpressure to the Sequence pump either through throttling it down with a valve or reduction in pipe to a degree puts no strain or wear and tear on the pump......I have gone back to the manufacturer several times with the question........I do installs, and have a Dart running on a 190 and there is enough flow from the pump to push the tank, plus the chiller mounted remotely and the chiller feed line is 1".

o ok cool good to know thanks for the info acrylic its always good to be corrected on an application...
the dart is an awesome pump i used it on my closed loop and its performed awesomely over the last 9 months and creates alot of flow in the tank!

i also run a drat for a return on one of the tanks. I even use a sequence hammerhead pump on the main. i am running more then 10000 gallons and hour THROUGH THE SUMPS. i love both pumps

Oceana is your figure correct 10,000 gallons???? That's some mad flow......I love my HammerHead and dead quite as well.......I love the Dart and use that to run alot of OceansMotions, but I think on my 8Way I'm going to run the Barracuda though??? :notsure: still undecided.....I have to talk to Paul before I make my final decision.

Ur right, my standard tank only had 1 x 1" overflow. Ive added a second overflow and opened up the 1" to 1.5". Alltogether its 2 x 1.5" overflows, ~ 3000 gph.
I was thinkin of getting a big pump so ive got enough flow for SPS in the future.

Dart would be a good fit with that configuration, but you'll have a hard time pushing that amount of flow through a standard sump.......To increase your turnover you might want to considering making the rest of your flow up with a CL system......

Im planning on drilling a 50 gal acrylic sump w/ a 2" hole to feed the return.
Is this going to be a bad idea? Is it better to use a smaller inlet to the pump? I dont quite understand these big pumps very well yet :notsure:

How would you normally plumb one of these. Ive never plumbed a tank or pump this size before. It sounds like i should run the pipes as far up before turning the water? A diagram would work wonders for me. :thinking:

Seems like it would be OK to add a valve to lower the flow if needed?

actualy thats an low number. Its really around 10400 somthing. all four systems are run together into one 155 gallon sump. the flow come from the tanks via a total of four 2 1/2 drains and two 1 3/4 drains.

The CL pump is going to be my next task, for another 1500-2000 gph for a total of about 4k-5k gph. I estimate ill get about 2400 gph at the tank(6ft head) w/ the Dart.
I came across the sequence pumps and notices how much flow, little wattage and the cost they were and they really caught my eye. Hoping to get as much value out of a single pump as possible

Thanks for all the response..

Got 2 more questions before taking off for work..
- How loud are the Sequence Pumps? and can i put foam or somthing under the pump to quiet vibrations, etc?
- Do i really need the Saltwater(SW) version of the Sequence pumps, or do the Darts work just the same.

well since my darts are 3 years old now and i think they look and perform like brand new i wouild say your good to go.
as for noise my entire tank room is almost silent. VERY little noise. i am a huge freak about noise. i am an audiophile and cant stand filler noise. i give the sequence line an A++ in silence and performance

I agree with Oceana about the quietness of the Sequence pumps.....my HammerHead you have to touch to realize it's running.....Yes you can put some sort of insulator underneath the pump or any pump for that matter......
The Darts come ready to run in saltwater so there isn't any additional items you would need to buy to get the pump running out of the box......Yes if you don't believe me call Sequence and talk to their techs, and they will tell you that valving these pumps down will not hurt or hinder them, but actually make them more efficient.....Alot of people are mislead, when I say that, but these pumps were engineered for that......when you apply a certain amount of backpressure (within reason) it causes the motor to downspin, which again is built for that and in the end no harm to the pump, and uses less electricity.......For the water flow the Dart moves it is a very economical pump IMO.........
Plumbing these puppies isn't any different than any other external pump.....You don't have to plumb the pump with 2" if you choose not too.....I forget what they said about the 2", but that is why they include a reducer with the pump to 1.5. It doesn't affect the pump either way you choose to go......2" would be great, but really not needed, and probably easier to work with 1 1/2", but I would run my plumbing that size till I had to reduce it for whatever reason.........
When I use the Dart on CL applications I do plumb them using the 2" only because I want to make sure they are flooded........You should see them run a 4Way OceansMotions, they are mad, and open them all the way up!!!!!!!

I have some pics of my plumbing and all is done in 1.5" since the HammerHead comes standard with 1.5", but I use hard PVC instead of flex PVC.....Flex PVC has less restriction, and is quiet, but I don't personally care for it, and only use it where I actually have to, or the bend is way drastic.....I tend not to use any drastic elbows and when I do change direction I try to use sweeps to reduce friction to a min.

Hey SLO.
I highly recommend using the DART. I use this for my 215 as a return. This is the only pump I use since it moves a bunch of water.
Noise level is very low and you can hear the hum just a little.
Here is my setup.
