LF return pump - GOT ONE!

[Fragzilla]

I am clueless when it come to what size of pump I will be needing but I need one. I am researching this tonight.

120 gallon reef 40 gallon sump with about 16 feet of head .

Anyone selling something that might be of interest to me.

Can anyone help me out with what I should be looking for and why?

Located in Calgary area only please.

Thanks,

Jeff

16 feet of head!? Wow, I didn't realize your sump was in the basement :-) The first step is to decide what flowrate you want through your sump taking into consideration how much flow our skimmer supports and how much flow your overflow supports and head loss. Just make sure your return pump does not flow more than your overflow. If your overflow supports more flow than your return pump, then your overflow will flow whatever your return flow is at.

Admittedly, it is a bit of a balancing act. If you are worried or uncertain though, just 'T' in a valve somewhere in the return line so you can flow some return back into the sump. This is handy for other uses as well so I would recommend doing it anyway.

I have never seen anyone with a basement sump that was able to use an in-sump pump as their return, although I am sure there must be some out there? Maybe? You may have to look at external pumps like the Dart, etc.

ummmm....... i think my 16 feet of head was out to lunch now.

See i said I was clueless

measure the distance from the top of the water in the sump to the top of the tank, (mines 3 feet) then add about 1/2 feet per 90 degree elbow, i have 3 feet up a 90 and a 45 my head is 3-4 feet

hope this helps

Ok, so not sure what your head loss is now since you're rethinking that calculation, but I will be doing a basement sump setup soon and have purchased a lightly used Panworld NH-150PS external pump in anticipation. Don't have the flow chart numbers at my fingertips but I do know it is pressure rated/biased for up to 23 feet of head. I anticipate having somewhere between 11 and 16 feet of head loss and I believe the NH-150PS will deliver around 700 gph under that.

Panworlds are similar/comparable to Iwaki pumps but somewhat less costly and I've seen only positive reviews on various forums so far. I've run mine for a short period in a mock up scenario with only a few feet of head pressure and it works well. A good hum to it but not overly noisy. Noise is not a huge factor with a basement sump anyhow.

I had originally wanted to do a 90 gal, but will probably go with a 120 now so I'm pretty sure this pump will fit the bill. I will be teeing off the return with a manifold to regulate any excess flow as suggested by Kien. Should be no trouble finding a use for any extra flow with refugium, skimmer etc. Can always plumb multiple return nozzles to distribute the flow in the display as well. On the discussion of external vs. internal, I've actually been contemplating running both, external in summer and internal in winter to help warm the water since it's cool in the basement.

Mike, I would really like to see this once it's done. On my next build I will be doing a basement fish-room/sump with a Sequence 3600 Blackfin that I bought.

I know you said Calgary area only, but this is a good deal on a very good pump. I don't know if Dez still has it though. If you google it, check out Dolphin Ampmaster.
