Return pump recommendation (2 dead ecotech pumps)

[sigmarabi1]

Hello,

I’m running 2 3100 gph current dc eflux loop return pumps . Here is a picture of them in my sump tank.

these look good, at a good price point. How long have you been running the for? Do you use filter pads underneath to collect debris?

I know I'm not the only one who the thread here on R2R about the changes in the impeller.
I just can't find that thread right now.

I have been running a Current Eflux 3170 for 8 months and have had no issues. It was one of only a few internal pumps that could deal with my head pressure(12'). It runs very quiet, when I am in my basement, I can hardly hear it.

I have had my eye on the current usa dc pump lately, but I don't know anything about is as far as reliability.

Company seems responsive too. Units appear to be covered under their standard 1 year warranty.

I'm not sure you'll get more than 1500GPH out of one of these under your installation.....but I forget what the target was.....does around 1500 GPH do it?

Any idea or guesstimate what gph you are getting at appx 12 ft?

they have 3 models: one runs up t0 3170 GPH..what am I missing?

It is running at about 55-60% and I would say about 400-500 GPH. But that is just that, a guesstimate

If I crank it to full it causes a lot of water noise and flow in the tank is crazy

You have to look at the pump manufacturers head loss chart and line it up with your specific head loss. Some 3k gph pumps produce less than lower gph pumps above around 5-6 ft. Head loss. The eflux and the sicce 9.0 I mentioned are close at or above 10ft. (According to the manufacturers charts)

The 3170 gph is at 0 head loss.

 

[mcarroll]

The install has about 10' of head pressure if I'm recalling correctly from earlier in the thead .

From their pump page: https://current-usa.com/pumps/eflux-dc-flow-pumps/

At 10 feet (or whatever it actually is if you take a good approximate measurement) you can see the big one will generate a bit over 1500 GPH. The mid-size about 700 GPH.

 

[WWIII]

Heres the Sicce 9.0 chart, just for comparison. According to the manufacturer's chart it produces around 1800 gph at 10 feet. So even though it is only 2500 gph max, it produces more gph than the eflux 3170 gph pump at around 10 feet head loss. Problem is it's kinda hard to just trust the manufacturer's charts at face value.

Seems strange that he would say that when there is this.

Technically, he is correct, apparently just doesn't have all the information. There weren't changes to the impeller itself, but there were major changes to the volute, impeller housing and impeller shroud as shown by the photos in the above link.

The L1's curve for handy comparison:

10' ≈ 1250 GPH by my eyeball

 

[Forsaken77]

Well, I haven't tried calling them yet. I should soon

Check out this thread and email them the pictures and thread. If they still give you a hard time, call and ask to speak to a supervisor. You gotta get them to acknowledge the problem in your pump.

I was actually looking for an L1 for about 6 months and they were sold out everywhere with no new stock coming in. Glad I didn't find it. That's how I know they pulled them until the new revision came out. They probably don't want you saying they replaced an L1 pump on a forum because everybody with the older models would be demanding a new pump.

But if you can get a new pump for free, that's the best bet. You just have to know how to sell it, lol.

I run a ehiem 1262 for the last 10+ years. It has been cleaned twice. Impeller never replaced. Sorry but you can’t really beat that.

Go AC or continue to drain your bank account.

The Sicce Syncra are great, and pretty quiet, and a three year warranty.

You can manually control the flow to nine different settings. I have the 2.0 and the 9 settings range form 251 GPH to 568 GPH

What kind is it?

Danner Supreme Magnetic Drive Pump
Actually come to think about it it's more like 20+ years since I had this running before we moved.
Last time I check it was 6 years ago??Still running strong

 

[mtraylor]

Hello,

The reason I went for two is because I have the dual over flows. I wanted to have control over each one for optimal flow is all. I easily could have ran one, but choice to run two instead, plus it also always me to run them at a lower level because the pressure is higher. So my pumps are only running at 15-20 percent.

Oh ok. Did you plan your plumbing with valves that you reroute flow to use only one pump should one fail? I thought about this if I went dc, that way I would have at least one pump that would work for me.

I have a backup dart, but its just in the closet.

So i'm kind of in the same boat. I have Vectra L1 that failed on me in Feb, the replacement they sent, is actually a good bit louder than the previous one. My flow rates are also varying quite a bit per the Apex FMM. I need to go through and re-plumb my entire return line for manifolds and what not. But right now I'm not trusting my vectra and looking at replacing with with RE Red Dragon 3.
