Recommendation for High Pressure Ext Pump

[Omair]

I'm exploring the option of setting up a large 300 gal sump in my basement and then plumbing my way up to the second floor with my Display Tank. I would like to know if anyone can recommend a high pressure flow pump that would work for me. It would be travelling atleast 24 feet with approximately 4 bends. I don't need a lot of flow in my DT from the pump, the powerheads can handle that.

you should PM bankyf. he has one for sale that might work perfectly for you. it's a huge pump he had in his basement to run a line upstairs to his tank, just like you're describing. i don't know what model pump it was though.

Thanks Ryan! Will do!

The Reeflo pumps are really good. They have a wide variety that will even let you use one as a return, feed your skimmer, feed reactors, frag tanks, etc. You may want to check Reef Central to find out what the best motor is because, as I understand it, you can get the same pump with different motors.

I think a sequence Marlin would give you about 1000 GPH at that head height. Double check me though.

When you say 24 feet, you mean vertical feet or horizontal feet or both? Also, when you say bends, do you mean 90 degrees? And if so, do you have the space to install "street sweep 90s"?

 

I frequently use http://www.pondarama.com/html/friction_loss_charts.html as a decent web site to SWAG head loss for a given setup.

As far 24', that would be total length. Vertical length total might be 8' or less. I might have room for street sweep 90 pvc. I was thinging of regular 90 elbows though, would those be a problem and cause too much head loss?

In that case I'd go with a sequence Wahoo.

The short answer is yes.

 

For 2" piping (which is the smallest I would go with for that long of a run, a standard 90 is worth ~6' of head, a med 90 sweep is about 4.5' of head and a long 90 sweep is worth about 3' of head.

 

I will go into more details later, with 4 standard 90s adding up to ~24' of head, that is a big difference.

I am a big fan of Pan Worlds or Blue Lines for a basement sump. I am using Blueline 55HD now and love it.

I just spoke with Fazio92 and after measuring it, I think I will have 12' of vertical pipe with aproximately another 14-18' of horizontal pipe. That would mean I need a pump that could put out atleast 3400gph at 12' vertical correct? To account for a manifold for reactors etc. as well as bends/bulkheads. Based on that I would have to go with a Reeflo Hammerhead?

How about an Iwaki MD-70RLZ? 11.4 GPM at 4' of head, with a max of 66' of head. Not sure if it'll be enough flow, but if you search them on google the first hit has them used for $50. I use one from that site to pump from a water storage barrel in my basement to my first floor.

Sorry, I was in a hurry yesterday when I posted, here is a better in-depth answer (using 1.5" outlet piping as a reference).

 

(remember the vertical distance is from the water level in the DT to the water level in the sump, ups and downs in between - like mounting your pump on the basement floor when the sump water level is chest high - do not contribute to the vertical distance)

 

Since flow velocity affects the head loss (faster flow = more head loss), these are for a relatively modest 1500 gph

 

12' vertical pipe = 12' head loss

18' horizontal = around .75 head loss (1.5" piping is a little under 4' head loss per 100' run, so the horizontal really doesn't contribute much although it goes up significantly for smaller piping)

90s as said above, these contribute a great deal (for larger piping, lower radius turns contribute more) = 5-9' head loss

Usually I throw a 15% factor on there for other misc. fittings and such.

 

So that totals ~20-25' head loss.

 

Based on that, I think a 1/3 hp pump is probably about what you will find that will meet your needs (will put you in the 1400-1600 gph range). Something like the 1/3 hp performancepro cascade http://www.azponds.c...dehighchart.jpg. I would do research to find the most efficient one (pull the power line off the pump curves to find the expected amperage draw for that particular flow rate).

 

I would do what you can to reduce the vertical height and number fittings in the return line, since the basement sump greatly increases the energy cost associated with moving water. Things like raising the sump off the floor, going as point-to-point strait as you can, etc. I can help with this if you want, let me know.
