Sicce Return Pump Selection

[Caleb123]

I am in the process of putting together an Innovative Marine 170 EXT with a Trigger Systems CR44 Sump. I plan to buy a Sicce SDC return pump for Black Friday but I’m not sure of which one to buy. Does anyone have experience with the 7.0 SDC or the 9.0 SDC?

I have a 7.0 on my 100ext suppling one return thru an UV.

I have a syncra sdc 9 pumping up from my basement @ 66%. 14' head 350ish gph. 4 years, cleaned it 2x. 42 dB

Do you like it?

do you like the pump? How long have you been running it and have you had any issues?

Do you like the pump? Do you believe that it is powerful enough for a 170?

Mine is pumping 220 gph at 29%

I am a firm believer in ALWAYS going slightly bigger.

Less wear and tear on a pump running at 50% rather than 100%, at least in my opinion.

I thought the 7.0 was 800 gph minimum

4 years, yes, powerful. My next build will be in a basement. IM 170 ext. This will be used as the sump pump. Way powerful enough for that.

 

[EeyoreIsMySpiritAnimal]

I'm looking at these pumps as well and trying to figure out if the 9.0 is overkill for a 140g plus sump

 

[Dburr1014]

That depends on the head.
Manufacturers always state @ 0 head.

Very good point!

at zero head

at zero head

Yeah, I forgot about that, lol.
How high is your pump pushing water? Mine will only be about 4.5 feet

I wish they would publish pump curves and different power setting. The only one I have seen do that is Royal Dragon.

Sump is under the tank so 36 - 42 inches not sure exact number.

They can be found.

Those are all at 100%

Well yes, but then you know you can turn them down.
For instance, I picked the 9 because I knew I need 14' head. It does 23. I could do 1500 gph @ 14' head.

But @KStatefan was asking about charts that showed pump curves at different power settings. My comment was that the chart posted does not show this.
