So other then the sequence pumps are there any other large flow pumps for these large setups? I am setting up a 400g tank and would like to use a single closed loop but need to find a good pump

depending on if you like more up front costs or less wattage you are better off going multiple superdarts then one hammerhead .
4300/gph 165/w for the dart = 26/g per watt
5555/gph 272/w for hammer head = 20/g per watt
The red dragon pump rd12 is not worth it at $900 for the pump 3170/gph at 115 watt for 27/gpw
hayward are not efficient at all.
With two pumps you have redundancy in case one pump goes out and you also have more flow options.
At the end of the day though for pure wattage vs flow you cant beat powerheads at all.

Can you get Laguna Pumps in USA? They are proving to be quite popular here in the UK. They use the same motor block as the extremely expensive Red Dragon pump and the only difference is the RD runs at about 24w lighter than the laguna but is about £750 more expensive!
Their specs are:
16000lph, 4226.752 US gallons
160 watts
£160/$257.630 USD to buy.
I am building a large system using several closed loops. I prefer several smaller pumps over one large one for a couple of reasons.
1) Redundancy. If one pump fails I still have good all round flow.
2) Efficiency. I can turn off a couple of the pumps over night to create a calmer more gentle night flow and reduce running costs.
Hope that helps

I know a curator of a public aquarium, and thats all he uses. There are no metal parts in contact with the water so they last longer than any other pumps in the gph range that he needs to work in.

I think I mentioned before on a different thread recently.
Tritron 420, now called Abyzz. You can't beat them. Costly, but you digitally control them. I also have a stream pump version, which controls the flow in my 1000G tank.
I run it at about 40% and it reads about 50W on the digital computer controller, which also tells you how hot it is running!!.
You can see what they can do on You tube. The technology in these pumps is far superior to any of those mentioned in this thread. They are German made.

The g/ watt isn't linear with these pumps. They are FAR more economic when run at around 60-70% power and tend to run at around 100W on the 420.
That's the reason for the price tag, but it's also why they are in a different league.
Running ball valves to adjust the flow

Do you have a link to the specific pump you are referring too?

Thanks for all the great feedback. I have been reading the 1350 gallon tank in canada thread that uses the Abyzz dc pumps and although I agree they are impressive, for $2000 they better do more then just move water.
I have a dart pump on my current tank and have had no problems with them and if I can't find a better option I will probably go with a hammerhead. I am planning on using a new style OceansMotions for the closed loop so multiple pumps won't be possible. I will be using the dart as my return pump to an OM 8way so between the two I should have lots of flow. If you look at the attached video, which is the 2 port version (I will be using the 4) I think you will agree that powerheads will have trouble making this flow pattern.

Ever seen a pump that tells you how hot it is running?. Or shuts down when the impellor is jammed and sounds an alarm, or tells you when servicing is due. You get what you pay for....
If you really wanted, the controller also allows you to run a digital ocean motions equivalent with up to 8 pumps running the outputs. Instead of the drum rotating, the controller decides which pump to run, but thats for huge tanks.
It sounds like you'd be happier with the Sequence pumps though.....
