would you do this to a new pump?

[onetrickpony]

Ertuncererdi you might try the Seio’s m2600 for a DIY ps

Hey spazz you wouldn’t have an m2600 laying around to test
With the air port out they push a lot of air, 55w 2600 gph
You would just need a uniseal to make it recirculating

Just a thought what do you think

Spazz, what are you using to build the NW disc, and what are you using for the pins?

pvc sheet and rod

Also, what makes this pump special? Is it the fact that its direct drive, and that makes it less likely to cavitate? (I'm trying to figure out why you wouldnt use something like a blueline ns800 thats obviously more efficient)

this pump is special because it is direct drive not mag drive. as a pump it puts out over 1100 gallons an hour at 4 ft of head and 90 watts. the blueline 1100 puts out 1100 gallons at 0ft of head at 70 watts.
also its almost impossible to convert the mag drive pumps to needle wheels. it needs to be a direct drive pump with a john craine seal. also the mag drive pumps have way too small of an inlet and outlet.

Also, building one of those 5 gal water bottle skimmers, so I'm looking at a 12" by 16"ish reaction chamber. Is this big enough for something like this?

i couldnt even guess about that because i wouldnt even think about building something like this.

PS. Was that your NW that the premium aquatic guys had at IMAC?

nope that was sequences design im assuming.

can you send me a link to this pump?

Hi Spazz,
Glad your back! I never miss any of your posts!

Anyway, I wanted to know which pump you prefer between the Dart and the Tiny Might. I need to buy a pump for a DIY NW and would like your input.

Also, can you run a skimmer inline? I mean, can you use the skimmer to feed a reactor and back to the tank without emptying in a sump?

Thanks.

the dart and the tiny might both have there place in the aquarium hobby. the tiny might pumps are being worked on for small skimmer under 700 gallons. the darts are good for over 700 gallons. for systems under 150 gallons the ocean runners are still my favorite pump. but i want to test out other pumps to see if there is one that will outperform the ocean runner 3700 or not. the eheim pumps are just too high priced for what you get. sure there at the top of there class for air output. but for $300 you can get alot more pump with 2 ocean runners and save over $100 for the pair.

i would never feed any other piece of equiptment off the skimmer. the reason for that is incase something causes the flow to decrease the skimmer would overflow and dump alot of skimmate all over the place. or put the skimmate back into the aquarium. the skimmer output should be free flowing to the sump.

thanks cemE

i looked into using a seio pump for that but there not as well constructed as you would think. i broke the shaft on mine from running air into it for a long period of time. the shafts are too small in my opinion. thd then there is the whole thing of taking a submersable pump and running it out of the water. it might burn the pump up. there wouldnt be enough cooling going on around the pump.
i feel the tiny might pump will work out just fine for a medium sized needle wheel. if you have to have more than 2 ocean runners on a skimmer then you would use a tiny might. if you need more than 2 tiny might pumps then you go to the dart pumps. and if you need more than 2 dart pumps then you get out the trusty evenrude outboard.

[spazz]

well here is the progress on the tiny might test skimmer.
i have been working on this inbetween trying to cut the needle wheel to go to florida. i will be glad when i finaly get that needle wheel done. its been nothing but a HUGE PIA! that pump is nothing like the dart pumps in its design so the impellor is super tough to build. im on the 5th try at it. i think i might have it fianlly.

for the tiny might i had to use a 10" tube for the test tank so i just slapped a skimmer base together quick. that way it can be tested properly. when its finnished i will haul it over to a friends house and have him test it out on his system.
man i wish i had big ugly back as a test tank. ha ha ha ha
well here is little ugly as chem E calls it. i liked the name he gave it so much i had to stick with it. ha ha ha thanks chemE.

[nebraskareef]

Awesome, can't wait to see what kind of bubbles this lil guy will spit out!

[ertuncererdi]

its looks really good. i really wanna see the bubbles

[Lunchbucket]

i really want to see it all fired up!!

Scott, The design looks good! Sorry about this morning bud! I didn't realize you had pulled an all nighter! If it is OK with you I will try again in the late afternoon. The ideas are swirling with this thing!

[radone]

This thing looks insane

"But I like it"

Awesome work as usual

[zapata41]

spazz, looks like you are a little ahead of schedule on this project, i recal you saying in a pm that it would be a few months out. so now that the project is underway, my test skimmer is waiting, 12" x 30" tall, you built most all the parts to it. currently i am running about 75lpm of air into it and would like a smaller bubble size and a little less power draw.

patiently waiting

Tim

[zapata41]

almost forgot the smiley.

[Roland Jacques]

spazz, looks good.

wouldn't it be ok to restrict the water & air flow inlet on this pump for smaller dia. skimmers.

im wondering how will this pump would hold up STOCK in salt water. on the stock pump with the 303 stainless shaft is the end/nut the only part exposed to the saltwater? its kind of seems like the old quiet one pump.

[smjtkj]

He is actually going to put an end cap over the shaft end so that there will not be any shaft exposed.

[Roland Jacques]

yeah, i got that thanks smjtkj, iwas just asking becacuse i no some one who is using this pump on a SW tank. i guess if that is the only part exposed on the stock pump than he should be ok.

Spazz: Please report on how hot the Tiny Might pump runs
after it's set up and running for a while.

While researching this little guy, I've read on a few forums that
the Tiny Might pump tends to run very hot. Too hot to touch in
some cases. One fellow said he returned 3 pumps before finally
getting one that ran cool. These forum posts were all at least
a year old, so perhaps overheating was a problem with an
early model. I'm very curious how your pump behaves.

[AcroSteve]

I would think that if they ran hot, the power draw would be higher.

Efficient pumps could be relatively cool. We should know more when Spazz takes some measurements.

Low power doesn't imply a cool-running pump. But now that
I think about it more, the heat complaints I saw were probably
the result of improperly using the TM as a sump-return pump.
The little 1/16 HP motor is adequate for circulation tasks, but is
perhaps a bit overwhelmed when pushing a 1.5-inch column of
water against a 4-foot head.

But for our purposes, the Tiny Might should be great driving a
medium-large needle-wheel skimmer. Spazz will let us know.

Slightly off topic...

Ever since Spazz's initial Dart thread, I've been eyeing the
new 98W Reeflo Snapper as an option for my DIY needle-wheel
skimmer. It costs roughly twice the Tiny Might and uses about
8W more power, but in terms of GPH-per-watt "efficiency", it
beats everything in the sub-100W category hands down...

Tiny Might ($115) -> 1200gph / 90W = 13.3
Reeflo Snapper ($199) -> 2400gph / 98W = 24.5
Reeflo Dart ($210) -> 3600gph / 140W = 25.7

I also like the idea of using the same pump model for my sump
return, closed loops, and skimmer. One extra pump could be
kept around as backup. Spare parts like SiC seals and o-rings
would also be interchangeable for all pumps.

But apparently the Reeflo Snapper is so new I can't find any
stats on the max head and such. MDM doesn't list it on their
web site yet.

sorry I haven't posted anything in a few days. its been a bad week all around. our truck rear end desided to poop the gears out the bottom the other day and I have been working on getting that fixed and driving truck at the same time. so no updates as of yet. may be this weekend though. I'm glad to hear all these different comments going on hee. keep it up it gives all of us something to think about while designing this new pump. if the heat becomes a problem I think a heat sink could be used to dissipate some of the heat. can someone check into round heat sinks that might work on the outside of the pump like the baldor motors have? I also have not see that reeflo pump you are talking about but it sounds very interesting. it might be an alternative to the tiny might pumps. have to see what kind of motor is on it first though. I'm hoping to do a wet test this weekend some time but no promises because of other priorities I have. will post pics as things progress. please keep posting these ideas it helps me come up with new and interesting things. I have found a home for this skimmer when its finished. it will be going to a local collage for testing. the biology teacher there has a 500g system I can test it on for a few weeks. I know I can get some great information from him on its performance and how well of a job it does on that system.

[spazz]

by the way hsvtoolfool you right on track with this thread. your not side tracking it at all. this thread is about finding a pump for medimum sized skimmers. not about this one pump. if there is a better pump out there then we need to explore it and see if it will work better than the tiny might pump. i will post some pics later as to why i really like the tiny mights. then you will see what i look for in a pump that will be converted to a needle wheel.

How about using a heat sink like they use on a home computer CPU
Get some light gauge sheet metal bend it like an accordion
WWWWWWWWWWW
Rap the motor using a SS hose clamp
The fins would draw away the heat from the motor
The increased surface area would dissipate the heat into the air

aluminum is the best though. and if we could find an extruded half round that would work all we need to do it disconnect the fan insidethe motor and add a 12v fan outsidethe motor. less watts to the motor and less heat also more rpm's.
