Low wattage return pumps

[SLO180]

Seems hard to find wattage numbers for the different brands of pumps.

Anyone know of good return pumps that have low power comsumption/low wattage. I need a pump rated for about 1400-1800 gal/hr. I figured if this thing was going to be on 24/7, the lower wattage will help save a lot of $$.

If the pumps are quiet, thats a plus too.

Also before buying a pump check on its wattage useage, I have noticed alot of people suggesting pumps that end up not being that effecient.

Why do you want such a large return pump? Big pumps use lots of power. Using the 3 - 5x display size return pump calculation, 1400 GPH is good for a 280 - 450G tank. Are you setting up one that large?

Im going to use a couple SCWD's or a squirt to split the lines. im estimating about 400-500 gph of losses through plumbing, head, etc

on a side note.. been looking at the Rio 26pump. Its an in sump, low power, about $80 new and does about 1600 gph before losses. Any thoughts anyone?

Look at eheim. They have a great reputation among hobyists and IIRC they are pretty energy efficient pumps.

Have you considered using a smaller return pump and create a dedicated closed loop for your SCWDs? You get a couple of benefits (fewer microbubbles, less overflow noise) from the slower flow rate through your sump while maintaining the higher flow in your display.

Is your sump room far away from your display tank to create such a loss of pressure/volume? My sump room will be around 35' away and I'm looking at a pump around 2000 gph for a 120 gallon display tank.

Mags are pretty good for power to gph

Take a look at the Ocean Runner pumps as well as the eheims. My OR 2500 is silent (in sump) and is only 35 Watts for 600 gph at 0' head.

here's a link to the manual with flow/head information:

I don't have a whole lot of experience with this pump (only a couple of weeks) but so far I like it quite a bit.

On a side note, I noticed fosters and smith also has these for sale:

i need to learn to be more articulate with my typing in the mornings :eek1:

Here is what im planning to do with the returns/closed loop (CL)

Reeflo Dart (3600gph) Closed loop hooked up to 2 SCWD's or some other wavemaker that has 4-6 outlets. im figuring for lots of losses in the squid since the inlet cones down to about 5/8 Plan is to split the return to ~4 lines (2 to the two SCWD's and two to the tank). After losses through SCWD's, check valves, valves, plumbing, head, etc.. rough estimation of ~1800 gph at the tank(used the RC head loss calc)

Ok, this is where the second pump comes in. want to use this to get ~1000 gph through the sump.

Total flow of about 2800 gph through the tank.

Link to pic of what im thinking of doing:

IM OPEN FOR SUGGESTIONS/IDEAS/HELP on pumps, setup, etc.. i do need help on all this since this is my first system this size.

sump is under the tank.. just plannin for SPS, so want the high turnover rate

If you want the best, and money isn't an issue, Red Dragon pumps are as good as you can buy.

 

[hahnmeister]

Red Dragons are not good return pumps though... they are low-pressure/high flow.

At that, there is no such thing as a low-wattage return pump. The whole point of low-wattage pumps is that they have larger shrouds, larger impellers, larger inlets/outlets, and spin slower. When you add head-pressure, their output goes down fast.

A pressure pump will require more watts per gallon moved, or the head-handling capabilities are much less. Smaller outlet, smaller shroud, and a faster spinning impeller... more watts.

My suggestion would be the external PanWorld 40PX, but if you NEED the higher flow, the Velocity T4 would fit what you want.

oh i can only wish that money isnt an issue :lolspin:

I bought a Velocity T4/Poseidon (newer) from a RC member- absolutely quiet and pretty small. Highly recommended for ~ 1100 GPH @ 4' head.
Energy consumption is not the best, but calculate the cost- not too much more for an ultra-quiet heavy-duty pump.

 

[dwdenny]

The velocity pumps add a lot heat to the tank because they are water cooled. I would watch out for that as well.

 

[TandN]

i have to say your wrong I have a red dragon return pump and by far the best I have owned to date and I have owned just about all the pumps that are insump. Mine is 2200 gph and uses 45w's

 

[wife no likey]

On a 120, you want more than 2800gph; more like 5000.

and a dart through two scwd's will cut it to nothing

 

[brad23]

If you don't have a lot of head a snapper would work well

 

[manofcoral]

I use the Dart on my 180 and I am super happy with it. Very quite and pushs a ton of water.
