Pet Forum / Aquaria / Marine Reef / December 2006Pump for 20 ft lift
I'm thinking of moving my whole sump to my first floor that has a great window w/ natural sunlight for a refugium. I think it's about a 16ft rise back to my tank (20' for margin of error), so would a regular oversized submersible pump work? I'd expect lower water throughput then it's rated, but then that's why it's oversized. If not, where would I find a suitable pump? --Kurt Checkouty a sequence 1000 pump with saltwater seals. IIRC it has a head pressure that will work in that height. AZPONDS.com is one and probably the cheapes tplace to buy one at. I think the larger Danner Mag drives will also work ok in saltwater and also provides sufficieint head push. External pumps http://www.azponds.com/new%20sequence.htm Submersible Pumps http://www.azponds.com/subpumps.htm Pondmaster Pro Hy-Drive pump are high head others are not. On Sequence pumps all can be used in saltwater and a salt water seal can be installed. <<>> <<>>I'm thinking of moving my whole sump to my first floor that has a great <<>>window w/ natural sunlight for a refugium. <<>> <<>>I think it's about a 16ft rise back to my tank (20' for margin of <<>>error), so would a regular oversized submersible pump work?

Thanks. You put me on the right track. Sequence pumps are external, and all can be retro fit with seals for saltwater use. I just got a load of used but like new pumps of which most were Sequence. These were all submerged in water after a storm here and folks had their pump houses or vaults flooded, as well as some that were merely exposed to lots ofrain. Ignorant homeowners that di dnot know any better all claled local rip off pond and water garden place here to come fix their outside koi and golkd fish ponds. Well companies are not gonna repair anyhting so they just instalalednew pumps and carried the others back to the shop and threw them in a pile outside, and I got them all. LAst count was 11 Sequence pumps and a bumch of other brands of pumps as well. I took em all apart, blew out any water, cleaned off any rust onthe inside of the stator windings, and allowed to air dry. I chjecked the bearings and if there wsa water in them I replaced them, Bearings are dirt cheap, so now I have 11 Sequence pumps from the 750 up to the self primers all runing nice and quiet as a churchmouse and do not have $50 in repairing them all and they all work just fine and have been operartionally checked and run, pumping water for at least a 24 hour period. I had to replace a capacitor on one but happened to have a few of that size capacitor anyhow. I also had a lot of the bearings I needed as well. Now I intend to separate all the burial vaults I have ganged together with flow thorugh filtration that I use to raise up godfish, koi and catfish as well as some other tropical fish like cichlids in so that I cancontrol each tank with a pump and filter individually. Life is good when you dumpster dive! ;-) Oh I also found a bunch of other old new unused stock like filter housings and media and weirs and water fall forms that they threw out. Yea I know its all freshwater stuff but it just goes to show how good Sequence pumps are and how reliable and easy to repair them. I have 5 Sequence pumps that I have in operation previously before this find that I bought new that has been in use for close to 5 or more years and have never leaked a drop or missed a beat, and run 24/7/365 <<>>Tristan wrote: <<>>> <<>>> Checkouty a sequence 1000 pump with saltwater seals. <<>> <<>> <<>>Thanks.

If these are large submersibles, you should be aware that they can heat up significantly at such high head loads. This could cause problems with maintaining a proper tank temperature. Just something to consider. George >>> Checkouty a sequence 1000 pump with saltwater seals. >> [quoted text clipped - 3 lines] > significantly at such high head loads.

Is there any relationship between the head pressure you use the pump with and the amount of electricity it uses up ? If so, I would guess the relationship would be that more head pressure would cause LESS power consumption for the same pump. I remember that this thing with submersible water pumps and power consumption was going against the, so called, "common sense" ;-) >>>> Checkouty a sequence 1000 pump with saltwater seals. >>> [quoted text clipped - 12 lines] > I remember that this thing with submersible water pumps and power > consumption was going against the, so called, "common sense" ;-) Most, if not all, submersibles rely on water flow for cooling. The more head, the less flow, the less the pump is able to shed heat. So it heats up internally (as well as the water it is sitting in) as the head increases. Most pumps today can handle this heat (unless the pump is deadheaded) to a point. Whether or not the critters in the aquarium can is another matter altogether. George >>> If these are large submersibles, you should be aware that they can heat >>> up significantly at such high head loads. This could cause problems >>> with maintaining a proper tank temperature. Good point. I think one of these two will work. I'm leaning towards the smaller one. http://tinyurl.com/ygagh8 http://tinyurl.com/ycx8fw They are both external, so air cooled. --Kurt The little Giant pump really leaves a lot to be desired especially how they get their head height. They reduce pipe size to a diameter half of what the intake is, so they are increasing pressure but at the same time decreasing volume so by speedingupo with a pressure increase the water flow thewy are able to push a smaller volume of water higher.....this amounts to pushing a pump continually on its max limits. I do not know about LG pumps in saltwater but they have a terrible reputation with ponders in general as to being problematic and energy consumers a compared to other pumps. Another hting is the Dolphin pump uses Emerson motors......which are a bottom line of economy motors, not nortoriously noted for longevity in lots of applications. The Sequence line of pumps use Baldor motors on their better pumps which is pretty well a well accepted industry standard and known for longevity. Sequence does use othe rbrands ontheir lower line of pumps Value line or Value flo or something like that, and if you compare specs you will see those pumps are also going to consume a lot more watts overall to attain the same performance as a Baldor powered pump does. Its allin the efficieincy of the motors......Personally I would wait and save up a bit more money if I was short and buy a top line pump with better energy consumptions figures and performance, as iat wil save $$ in the long run. I have a heap of Sequences in use around my ponds here and they are trouble free..... <<>>George wrote: <<>>>>> If these are large submersibles, you should be aware that they can heat <<>>>>> up significantly at such high head loads.

This one had a better performance profile. I know it will work and I can add a second display tank on my 2nd floor. --Kurt Coralife Turbo Sea High Pressure Pump http://www.bigalsonline.com/BigAlsUS/ctl3684/cp18557/si1379078/cl0/coralifeturbo seahighpressurepump1100p http://www.bigalsonline.com/BigAlsUS/ctl3684/cp18557/si1379079/cl0/coralifeturbo seahighpressurepump1740p >>> The little Giant pump really leaves a lot to be desired >> [quoted text clipped - 9 lines] > > --Kurt >>>Checkouty a sequence 1000 pump with saltwater seals. >> [quoted text clipped - 5 lines] > > George These are external. >> Checkouty a sequence 1000 pump with saltwater seals. > > Thanks. You put me on the right track. My recommendation would be an Iwaki MD55RLT - will handle a 26' head. Not cheap, tho. Somewhere in the $275 neighborhood. You can get Flow-vs-Head height from the pump manufacturer of the pump. 20' you'll be paying out the a.s for a pump. Here is a better idea for lighting. This is what I use and it works GREAT !!! http://www.melevsreef.com/fuge_bulb.html Chris > I'm thinking of moving my whole sump to my first floor that has a great > window w/ natural sunlight for a refugium.

I have limited room in my living area on 2nd floor, but plenty of space on my 1st. Thanks for the idea. 19W would be more efficient then a 200 W pump. I need the visit the local livestock store to see about a large tub. --Kurt > Here is a better idea for lighting.

Seems like I have some other priorities (parasites, reverse osmosis, lights, etc.) so I'm delaying the fug/pump idea for now. Although I did find a 150 gallon ($139) trough that would be perfect..... --Kurt |
