Flow Accelerator (eductor) W/Sequence Dart Pump

[Captain Bucket]

Can your Pacific Coast Flow Accelerator FA-400 3 / 4 Item Code: FT0031 be used in conjuction with a Sequence Dart pump?

I'd like to use two of these with an operating head of about 5'

Hello,

Thank you for your post, after looking at the flow Accelerator closely I would not recommend it for use with the Sequence Dart Pump. Due to the openings on the outlet side being as small as they are it would put a lot of strain on your pump it would create back pressure since it has very small openings on the outlet. This could possibly damage the Sequence Dart Pump, this type of damaged is not covered by the pumps warranty.

I hope this information helps you

Aw shoot! I placed an order for two Saturday! Are you sure they won't work out? It is my understanding that low pressure high flow pumps like the Dart can be choked back (which BTW I do) to throttle flow. I have to choke mine to keep from overwhelming my overflows. They are even supposed to consume less energy when throttled.

I was primarily worried that my pump couldn't develop enough pressure to make the eductors function properly, I really didn't consider back-pressure a worry. My order was confirmed but it hasn't yet shipped.

Hello,

Thanks for the reply, I can't honestly say that it would work without any damage to the pump. I'm just a little concerned about it damaging your pump and finding out that it is not covered under warranty due to improper use. Better to be safe than sorry.
I would recommend that you contact sequence directly and ask them if what you want to do will not damage the pump. You can contact them at 877.378.6798. If by any chance it will not work I would be more than happy to take back the Pacific Coast Flow Accelerator

Thanks for your concern Walter, and I'll take you up on your advice.

Walter, just to catch up:

I emailed this to Reeflo Pumps:

"Hello Chris: I've got a Sequence Dart I bought about a year and a half ago from Marine Depot, about which I have no complaints, except that the motor seems to be running hot, and by hot I mean I can't rest my fingers on it for over a second or two. Is this normal? Also, I have a couple of eductors with nozzle diameters of approx. 3/8" each. I assume that if I use them back pressure should not be a problem as the ability to 'valve down' is described as a feature of the pump. Nevertheless, I thought I'd check with you guys first before I install them in case I assume wrong. Thanks for your time

This is the response I got:

"The normal skin temp for a Dart is about 125 degrees. The motor was designed to dissipate heat thru it skin and not thru the shaft to the water.. Excessive heat is caused by bearing failure... if the bearings start failing, you will hear it loud and clear. You should also know that the motor has a thermal overload switch that will shut the motor off if the heat becomes excessive.
You are correct about the valves...it will simpole inmcrease the head pressure (a little) and cause the pump to operate further back on the curve..."

I've since been operating my return with the 'flow accelerators' (for about two weeks now) with no problems, and I'm delighted with the result so needless to say I won't be returning them. Thanks for your trouble.

Captain Bucket,

Are you still happy with those flow accelerators? I'm thinking of getting two- 3/4" versions for a closed loop system on my 90 gallon. I'm also looking to hook them up to a Reeflo Dart (3600 gph) but with a pair of 3/4" Sea Swirls that I already have. I'll probably have 2 additional returns besides the above two. And if it's still too much flow, I will have a gate valve to throttle the pump back. Each 3/4" model Sea Swirl can handle a maximum of 850 gph.

How many returns do you have coming from your Dart pump?

I'm also thinking about getting a 1/2" version to hook up to a 1/2" Sea Swirl that I'm going to hook up to a Eheim 1262 pump (898 gph) on my 30 cube, again another closed loop system. I will probably have one other return from this pump besides the flow accelerator. Each 1/2" model Sea Swirl can handle a maximum of 550 gph.

Thanks!
